Abstract: The invention relates to an AC to DC converter having an improved power factor achieved by combining boost converter operation at the beginning and ending of each half wave of the AC input waveform, with passive operation at the middle portion of each half wave. The timing of the operation is based on comparing the instantaneous voltage with a stored average voltage, which has the effect of making boost converter operation go off at a fixed angle after the beginning of each half wave and go on at a fixed angle before the ending of each half wave, the angles being independent of the average AC voltage. The converter increases the power factor to a value between 90 and 97% and reduces the current waveform distortion to between 15 and 29%.
