Controlling Brushless DC Motors to Tackle New Challenges
Rudy Ramos  
1/5/2019   Post a comment
The advantages of BLDC motors extend beyond merely enhancing reliability and relieving the audible noise and electrical interference associated with carbon commutating brushes.
Designing Drivers for Piezoelectric Motors

Piezoelectric motors are increasingly popular for linear motion, but the design of the accompanying drivers is very different from those used by traditional electromagnetic motors.
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.
Designing with Chip Capacitors for High-Voltage Safety and Reliability

How can you accurately measure this impedance to give reliable lead-off detection in ECGs?
Fast switching transitions can yield some disadvantages. Interference in the frequency range of the switching transitions between approximately 20 MHz and 200 MHz increases dramatically.
The U-channel format consists of an open frame PSU mounted into a U-shaped aluminum chassis.
The primary difference between the speakers I designed and the micro- and mini-speakers that Eminence makes is that the diaphragm is connected directly to the voice coil as opposed to an Aluminum or cardboard 'former' to which the voice coil was connected
Autonomous driving represents one of the most interesting fields of research in the electronics and automotive sectors. This interest is growing by means of projects like the “Roobopoli” which includes the design and testing of prototype autonomous cars having integrated microcontrollers.
