  • Patent number: 6300723
    Abstract: An apparatus for power factor control includes a capacitor for producing a substantially DC voltage and a switch for controlling the amount of energy stored in the capacitor in response to a switching signal. The switching signal is produced by the power factor controller and is based on a sinusoidal waveform that is independent of the waveform of an AC supply voltage for energizing an electric load.
