What is Power Factor Correction?

The power factor correction is a technique of increasing the power factor of a power supply. Switching power supplies without power factor correction draw current in short, high-magnitude pulses. These pulses can be smoothed out by using active or passive techniques. This reduces the input RMS current and apparent input power, thereby increasing the power factor.

Answer 2

Answer:

Power factor correction is the process of increasing the power factor to near unity without altering the original load. The power factor of a network is a measure of how efficiently the power is used and power factor correction is technology and equipment used to ensure this is as efficient as possible.
