Introduction to Switch Mode Power Supplies (SMPS)
www.microchip.comPower Factor Correction (PFC) is becoming a government mandated requirement for power supplies in countries around the world. PFC is the process that insures that the input voltages and currents from the AC power line into a power supply are in phase to achieve a “Unity Power Factor”. PFC is very costly to achieve in a linear power supply.
