ABSTRACT:
Harmonic currents of the line frequency on the input line of a power converter are significantly reduced by actively controlling the input current to have substantially the same waveform and be in phase with the input AC sinusoidal voltage. Specific peak current control techniques are utilized to constrain current in an input inductor to be in phase with and approximate in waveform the input voltage sinusoidal waveform by operating a switch at a much higher frequency than that of the input AC voltage source; with the peak current control using the input AC voltage as a controlling reference voltage waveform.
