Power quality issues involve all aspects of power system operation, from steady-state voltage regulation to the control of high-frequency transients caused by lightning or switching operations.

With the ever-increasing complexity of today’s printed circuit boards, the many voltages required to properly power all the integrated circuit loads are now managed by a range of point of load (POL) ...

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 ...
