Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of consumer electronic devices, including laptop adapters, LED driver power ...

When it comes to the most typical cause of poor power factor in a facility, motor inductance is a likely culprit. The problem worsens when motors are not loaded to their full capacity. Harmonic ...

Ideally, the power factor should be 1; then the load appears as a resistor to the AC source. However, in the real world, electrical loads not only cause distortions in AC current waveforms, but also ...

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 ...

Electric vehicles (EVs) use several kilowatts of energy to drive the ac synchronous propulsion motor from 400-V lithium-ion (Li-ion) batteries. The dc/dc circuits used to charge the batteries generate ...
