Modeling Magnetics in SPICE
Scott Deuty 7/27/2018 3 comments
Of all the components that go into a circuit, magnetics seem to have the most complexity in terms of several factors including construction, parasitics, linearity, and variations.
Automotive Ignition systems
Scott Deuty 7/27/2018 Post a comment
Automotive ignitions systems have seen many transitions over the years. Historically, the designs have matured from a magneto to today’s coil-over-spark plug designs. The progression follows the emergence of solid state electronics as well as the phasing out of mechanical components in favor of electrical components.
Why All This Stringent Testing?

I’d like to take a step back from the details and specifics related to radiation testing and focus a bit on some of the reasons that advanced testing and screening is performed on space qualified products.

High-speed data converters can now digitize or generate signals directly at radio frequencies (RFs), replacing traditional RF components such as mixers and local oscillators (LOs) with digital processing
Remembering the Apollo LEM Moon landing

It was July 20, 1969 when Neil Armstrong became the first human to step foot on an extraterrestrial body---our Moon. Today is the 49th anniversary of that momentous event and we celebrate it in anticipation of next year’s 50th anniversary celebration
Power inverters, batteries and Supercapacitors

A supercapacitor boost technology called S-CAP BOOST designed for backup and peak power solutions to industrial and medical applications. This technology is based on the latest supercapacitor technology and combined with intelligent control and monitoring
DC-DC Converters Redefined With 'Micro Modules'
Rudy Ramos 7/5/2018 Post a comment
DC-DC converters operate at all power levels and complexities. At some low levels it can make sense to design and ‘make it yourself,’ but at higher powers, a pre-assembled module becomes more cost-effective. New ‘micromodules’ shift that point to lower levels.

This is a throw-together project using junk box parts that can be useful whenever an interesting-looking waveform is needed for a demonstration or for the beginnings of a video test generator or curve tracer.
Analog circuits inherently have some inaccuracies; if these exceed the allowable specification, there are three general strategies to dealing with them.
Removing the vuvuzela narrow-band noise was presenting challenges to broadcast engineers
This article discusses how using a single synchronous buck controller can output the most common voltage rails, and accommodate a wide range of operating input voltages from 3V to 40V, and at a reasonable BOM cost.
This article explains how the latest-generation SiC FETs are ideally suited to new inverter designs with lower losses than IGBTs and proven robustness against short circuits, even at high temperatures and under repetitive stress
