Power factor correction (PFC) devices are circuits or modules that improve power quality and efficiency by reducing the burden on the supply. Power factor is a characteristic of a power supply’s load defining the ratio of the real (active) power being delivered to the load to the apparent power being delivered. The apparent power is the absolute length of the vector sum of the real and reactive (stored) components of the power. It is caused by the voltage and current waveforms being out of phase because reactive components in the load require energy to maintain their electric field. A corrector changes the relationship between the AC voltage and current waveforms required by the load as seen by the source. This reduces the burden of the sou
