Passive power factor correction (PFC): Improves PF by filtering out harmonics using passive filters. This is typically used in low-power applications, but is not enough at high power. Active power factor correction (PFC): Uses a switching converter to modulate the distorted wave in order to shape it into a sine wave.

To raise 81% power factor to 96%, select the multiplier from Table 6. 0.432 x 400 kW = 173 kVAR. Use 180 kVAR to ensure a 96% power factor.
