Second-stage output filters are often used to attenuate the output voltage ripple of a switching power supply. They can also isolate one load circuit from another. In this power tip, I will describe ...

What is the best strategy to get the best rate of change in the PID for a manipulated variable, or is there a more elegant ...

A dc-to-dc converter regulates a varying input voltage to a (usually) fixed output voltage via a feedback control system. The feedback control system should be as stable as possible to avoid ...

While current control and PWM switching play the most direct role in driving brushless DC motors, the motion profile and ...

Nyquist-sampling theory lies at the heart of today's digital-communications systems. It requires that data-conversion systems include antialiasing input filters. Designers need to understand the ...
