This paper gives a detailed engineering report of a PFC power supply using HiperPFS PFS729EG integrated PFC controller. It is a general purpose power supply which operates from 180 VAC to 264 VAC ...

The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.

Question: How do you measure inductor current? Answer: Switched-mode power supplies commonly use inductors to temporarily store energy. In the evaluation of these power supplies, it’s often useful to ...

Various switchmode power supply topologies use inductors for energy storage. The photos, below, show examples of an unshielded (left) and shielded (right) power inductor. The necessary inductance ...
