While applications for 1-Phase PFC are now familiar and prevalent, the same is not the case with 3-Phase PFC. Many equipments using kilowatts of power from 3-Phase mains should be candidates of ...

1. Power-factor triangle relates the real power, the reactive power, and the apparent power. (Courtesy of Vector Group) Let’s start by talking about the concept of power factor (PF). Assuming ...

Soft-recovery diodes greatly reduce EMI. Switching power supplies have become the norm in almost all electronic systems. The switchers' excellent line and load regulation, high conversion efficiency, ...

Linear Technology Corporation’s LT3798 is an isolated flyback controller with single stage active power factor correction (PFC). Efficiencies greater than 86% can be achieved with output power levels ...

Understanding power factor (PF) is important because it gives us a clear understanding of the efficiency of an electrical system. Put simply, it’s the ratio of true power and apparent power, which ...

By their very nature, power factor correction capacitors are special devices that operate close to their dielectric breakdown limits — time, temperature, and peak voltage, all of which contribute to ...
