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.

docs.rs-online.comThe power factor usually being referred to as cos Ø. The power factor is usually between 0.7 and 0.9, however this may vary depending on the motor size and rating. If there are many motors in an installation they will consume a lot of reactive power and will therefore have a lower power factor. Power supply authorities sometimes require the
