 PFC
 

Power Factor correction (PFC) is the technique of adjusting the timing and wave shape of the input current in order to maintain the waveform of current and voltage to be in phase or as same shape as possible. An improved power factor will be closer to 1, meaning the real AC power is closer to the apparent power.

A higher power factor correction power supply can cut electricity bill; increase system capacity and reduce the harmonics that benefits the society as a whole.
