What Is Digital Power?

In advance of our chat session on Wednesday, Nov. 19, at 1:00 p.m. EST (10:00 a.m. PST), we will present three introductory tech blogs on digital power: this one today, Nov. 13, another one on Nov. 14, and a final one on Nov. 17 in order to stimulate your questions for our chat session.

Digital power comprises power applications that use digitally controlled power products to provide configuration, monitoring, and supervisory functions, which extend to full loop control using digital algorithms.

    @Steve: great blog series, I appreciate it very much. I like the digital power approach because it combines the effectiveness of the modular designing process with the power of integration strategy. I think that many big companies will utilize this approach.

    @etnapowers: Well actually many big names in many industries have already started it. They might not have gone through with it but surely in the process. Anyway we do need time to evaluate since its quite new.

    @uchiha —I have personally witnessed large companies designing with Digital Power in the early 2000s, Alcatel-Lucent in Central Office equipment. Now in 2014 there are many, many companies large and small who are adopting Digital Power for all the great benefits you just can't get from an analog power supply.

     

    Analog power will not disappear, but for sure, Digital Power is quickly growing.

    Chat session on this and related topics next Wed, Nov 19 11am MST should be very interesting. I have dealt with IP as a patent examiner contractor for the USPTO on this and similar technology from all the top power electronic control systems companies so I will give my 2 cents during that time.

    @uchiha: A certain amount of time is necessary to evaluate the long term advantages of this solution, I think that this evaluation will be positive because the strengths of this solution are more than the weaknesses. This means that likely it will be a successful task.

    @uchiha: Yes we will have to see how this will fare, but more importantly since being digital the integration and configurability will increase which will further increase its value

    DSP chip TMS 320 series had been released in the market more than 20 years ago. Basic architecture is very similar among TMS 320 series except adding more features such as temperature sensor. But, seeing each feature identifies lots of change between TMS 32010 and TMS 320F2803X. TMS 32010 combines the following elements onto a single chip: Volatile 144 x 16 word RD/WR data memory, double-precision 32 bit ALU/accumulator, fast 200 ns multiplier, 16 bit data bus, autoincrementing/decrementing register, single-vector interrupt, and on-chip oscillator.

    @amrulah: Yes the value will increase but in a way its good because with time things will get fine-tuned according to the market needs

    True uchiha, I also do agree with you on this. When it's come to new thing it will spared in the market with no time if it is really a good and there will be a more fine tuning things with the help of other experts.

    Etnapowers, do you mean to replace the existing analogue power to the digital power?

  12. etnapowers
    November 19, 2014

    @Ranasinghe: I think that the digital power won't replace entirely the analog power, it will be added as an alternative solution, depending on the particular type of application to implement.

  13. uchiha
    November 23, 2014

    @ranasinghe: What are the deciding factors you think when a new thing comes out to the market to spread ? Is it the quality or the price ?

  14. PCR
    November 24, 2014

    Yes etnapowers, there is pros and cons in the both power option, in future there will be combination of both system in order to maximize the effectivity and efficiency.

    uchiha I believe that the both are interconnected thing  price without quality will die soon and quality without price  is impossible to manufacture. 

  16. ue2014
    November 24, 2014

    @ Ranasinghe – Correct. Quality and price are two interconnected elements which is very sensitive for a New Product which comes out to the market. 

    I think the real thing customer would look at a new product or even on a regular purchase is “Value for Money”. People should feels that they are getting a value for what they spent, either it should be expensive or cheap. 

  17. ue2014
    November 24, 2014

    @ Ranasinghe – yes, in the future both Analog and Difital would be used but Digital in major I guess. Analog will be used to situations where it is essential or situations where Analog provides better results that Digital. 

  18. uchiha
    November 25, 2014

    @ranasinghe: Yes but do you think you can balance the both in a high margin where the company can gain profits as well as the users gain high quality service ? I have my doubts over it 

  19. geek
    November 25, 2014

    @Steve: What do you think are the major applications of Digital Power? Will it replace all the applications that are currently served by the analog power, or will it have specific applications?

  20. geek
    November 25, 2014

    “People should feels that they are getting a value for what they spent, either it should be expensive or cheap. “

    @ue2014: I think that may not always be the case. There are several superior products that have higher features and they seem to be offering a great value, yet they don't sell a lot – precisely because the customer does not consider the features to be off much use or importance. In other words, the perceived value of these is fairly low compared to real value.

  21. ue2014
    November 25, 2014

    >>>>> they seem to be offering a great value, 

    >>>>>  precisely because the customer does not consider the features to be off much use or importance.

    >>>>>>>>>  the perceived value of these is fairly low compared to real value.

    @ tzubair – Exactly. People will only spend if they get only a real value for their money only. A lot of features may be in vain if those features does not provide any value to the customers even thought they seems like. 

    As you correctly said, people will look at the real value of the product. In my opinion also the word I used 'Value for money' stands for the real use of the equipment to the end users, not the features that is on offer with the equipment. 

  22. PCR
    November 26, 2014

    Exactly  ue2014, if it is cheap there won't be any issues but if it is expensive. Customer expects more value for money and the high quality. 

  23. PCR
    November 26, 2014

    Yes fir sure uchiha, there is a higher possibility of having a high profit margin in quality product or service. 

  24. uchiha
    November 27, 2014

    @ranasinghe: Its not always the quality that gets you a higher share of profit. It involves a lot entities like marketing, brand name, after sales, etc…

  25. uchiha
    November 27, 2014

    @ranasinghe: What do you mean by if its cheap ? Quality comes 1 st and that is the ultimate reaching point but cost too plays a major role

  26. chirshadblog
    November 27, 2014

    @uchiha: I guess cost plays a major role as long as the product is being accepted in the market. So there should be a balance between the price tag and the quality

  27. chirshadblog
    November 27, 2014

    @uchiha: Indeed, and agreed with you 100% on it. There are so many factors that get involved in deciding the profit but it will make their tasks much easier if the quality is excellent

  28. dassa.an
    November 28, 2014

    @Uchiha: Well a good point you have made here. My concern is that if the price is too high the targeting groups too get differed. You cannot target a small scaled market here isn't it ? If so the demand ratio will decrease. 

  29. dassa.an
    November 28, 2014

    @Uchiha: Mate do you think that just the quality will not do the job ? 

  30. ue2014
    November 28, 2014

    @ Ranasinghe – >>>>>>  if it is cheap there won't be any issues >>>>

    Even when it is cheap, that has to provide a certain value for money. People could go for cheap things due to two reasons. 

    1. Even though they have the buying capacity to buy the High Price Product, they would not concern about quality very much as they believe even the cheap thing would do the job for them. 

    2 That's their best buying capacity. 

    Specially in the second senario, people expect the 'Value for Money' they spent.

    @chirshadblog – >>>>>>>>> Indeed, and agreed with you 100% on it. There are so many factors that get involved in deciding the profit but it will make their tasks much easier if the quality is excellent >>>>>>>>>>

    Yes indeed. Profit is basically involved in every part of the process. But good quality product will allow the organization to enjoy that special bit of 'Extra High portion on Price' due to the good quality and the brand name for the product in the market. 

  32. ue2014
    November 29, 2014

    @dassa.an >>>>> I also think that Qualituchihais right. Only quality will not do the job for you. There are so many other factors involved in the process if you want to higher profits from a product. Quality idls only one element on it, yet a very important one.

    “In my opinion also the word I used 'Value for money' stands for the real use of the equipment to the end users, not the features that is on offer with the equipment. “

    @ue2014: I agree. It doesn't make sense to measure value for money with just the features. You have to consider what the user is deriving from it and place a number to that. Only then can you compare with the cost to see if the user is really getting any value out of the spending.

    In our culture there is a maxim that goes something like: “exepensive gets bitten once, cheap many times”.

  36. SunitaT
    November 30, 2014

    I guess cost plays a major role as long as the product is being accepted in the market. So there should be a balance between the price tag and the quality

    @chirshadblog, but sometimes cost doesnt play a major role. For example most of the Apple products are priced very high compared to other mobiles but people still buy Apple phones because they pay premium to the brand. So pricing is a tricky issue.

  37. SunitaT
    November 30, 2014

    There are so many factors that get involved in deciding the profit but it will make their tasks much easier if the quality is excellent

    @chirshadblog, true. Quality is the most imporatnt parameter. If you can manufacture quality products and build market and brand for the product then people dont mind paying extra money for the product. Customer support will also determine how people percieve the brand.

  38. SunitaT
    November 30, 2014

    My concern is that if the price is too high the targeting groups too get differed.

    @dassa.an, one of the way of pricing the product high and still targetting a bigger market is by manufacturing high quality products and giving excellent services to the customer. This strategy is successfully applied by Apple.

  39. SunitaT
    November 30, 2014

    In our culture there is a maxim that goes something like: “exepensive gets bitten once, cheap many times”.

    @nasimson, thanks for that maxim. Really meaningful. We should keep this fact in mind when we intend to buy new products. Quality products are expensive but if you buy quality products can last longer and also you can get good service from the company.

  40. SunitaT
    November 30, 2014

    Product, they would not concern about quality very much as they believe even the cheap thing would do the job for them. 

    @ue2014, this may not be true always. Many people buy low priced products assuming it would do the job for them but later repent once they realise the shortcomings of such products. Its better to pay extra money for quality products.

  41. SunitaT
    November 30, 2014

     I think that the digital power won't replace entirely the analog power

    @etnapowers, I totally agree with you. Since the physical world consists of signals in the continuous-time domain, analog circuits will be needed in the foreseeable future.

  42. SunitaT
    November 30, 2014

    It involves a lot entities like marketing, brand name, after sales, etc…

    @uchiha, true. It does involve entities like marketing, brand name etc but what if the product lacks quality ? Do you think people will buy low quality products if you market it well ? Its always better to have high quality product irrespective of the amount of effort you are going to put in marketing the product.

  43. ue2014
    November 30, 2014

    @Sunita TO >>>>>> Many people buy low quality products assuming they would do the job for them but later >>>>>> Exactly the same point I tried to make out. You say people assume which in other words I said people believe that low quality products would do the Job for them. I also agree with you for the later point that you make out. It's always better and safety to pay extra money for quality products.

  44. ue2014
    November 30, 2014

    @Sunita TO >>>>> Agree with you. When you have created a high brand value for your brand name in the market, such markets are lesser price sensitive.

  45. ue2014
    November 30, 2014

    @Sunita TO >>>> Totally agree with you. When you have a good quality products, it makes the marketers life easy and quality products will make sure such products will stay in the market for longer time period with the help of marketing as well since those products prove what marketers promote is true.

  46. dassa.an
    November 30, 2014

    @ue2014: Yes once the platform has been laid by the development / engineering or whoever it concerns the marketing team's job is very easy. If the quality is good and if you have got the branding properly, the customers will come to you rather than you going towards the customer

  47. dassa.an
    November 30, 2014

    @ue2014: Do you think its only the brand name that make a difference ? 

  48. dassa.an

    It's always better and safety to pay extra money for quality products.


    @ue2014, not just quality but reliability also plays a major role. For example Apple iphone 6 which was made of high quality was not reliable and thus was rejected by people. That is the reason people are still buying iPhone 5s.

  50. Sachin
    November 30, 2014

    When you have created a high brand value for your brand name in the market, such markets are lesser price sensitive.

    @ue2014, true. Many people prefer paying extra money for branded items. If people start getting high quality products for lesser price then may be such branded products prices might come down.

  51. geek
    November 30, 2014

    “Do you think people will buy low quality products if you market it well ? Its always better to have high quality product irrespective of the amount of effort you are going to put in marketing the product.”

    @SunitaT0: I think it's about giving the best value for user's money and ensuring that the value you deliver meets the perceivied value of the product. If something is of a low quality then the price should be such that it seems that the customer is getting the best possible quality for the product in the price he's paying. Even low quality products can sell if they're priced well.

  52. chirshadblog
    November 30, 2014

    @tzubair: Indeed treating the customer with the best is what matters. That will keep them coming back to you as well as recommend others too.

    @Ranasinghe: I hope that this integration will be possible. I think that it is the best strategy to get the best part of both worlds. I think that the integration presents some challenges, like the major part of hybrid projects that integrate two different solutions. The communication of the parts and the efficiency of the mutual insulation of the parts are key factors to ensure the success of this solution.

  54. etnapowers
    December 12, 2014

    @SunitaT0: You're right. Let's think for example to the conversion of a signal from analog to digital. Whatever will be the efficiency of the conversion, a small part of the signal content will be lost and the BER is never exactly zero. The world is “analog” and this is a good thing because any time continuous signal can be processed in a real time effective mode, to achieve great functionalities of the ICs.
