Abstract:
1. A power factor correction system comprising: a first rectifier that rectifies the voltage of an alternating current (ac) power source to produce a voltage waveform that transitions from a minimum amplitude to a maximum amplitude and back to the minimum amplitude, in a half sinusoid, twice in the period of the ac power source; a first phase winding of a motor that conveys current induced by the voltage waveform; a first storage component; a first regulator that regulates the flow of current conveyed by the first phase winding to the first storage component so as to store energy in the first storage component; a second phase winding of the motor; a second regulator that regulates the discharge of energy stored by the first storage component by conducting current through the second phase winding; and no circuit path exists for the first storage component to discharge stored energy by conducting current through the first phase winding.
