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 ...

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 ...

A SPLL (software phase-locked loop) is used in this Design Idea to generate a synchronous reference to common-mode powerline interference in two-electrode ECG amplification. Though intended for ECG ...

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