power factor correction. The use of capacitor banks occurs with passive PFC and helps to correct nonlinear electrical loads and stabilize the flow of current. Active PFC usually employs a system that controls the amount of power utilized by a load, keeping the balance as close to unity as ...
Firstly, the current waveform is in phase with the voltage, and secondly both waveforms are sinusoidal. Fig 1: Input voltage and current waveforms for a device with PF = 1.0 In practice, some devices do have unity power factors, but many others do not. A device has a poor p...
