Abstract:
A boost chopper circuit is described that an alternating current (AC) power source; at least one inductor connected to said AC power source; a rectifier connected to said inductor and AC power source; at least one switch shorting our said rectifier; a series circuit connected in parallel with said switch of at least one diode and a capacitor; and a load connected in parallel with said capacitor. A control technique is employed that includes turning on and off the switch in order to keep the average current per pulse cycle proportional to the AC input voltage during the same pulse cycle.

Claim (Index 9):
A power factor correction circuit to operate in a discontinuous current mode comprising:\n a three-phase alternating current (AC) power source; three capacitors star-connected across the three-phase AC power source; the source of three-phase AC power connected to respective center taps of three transformer primaries; anodes of three first diodes connected to respective first ends of the three center-tapped primaries; cathodes of the three first diodes shorted together and denoted as a first short; cathodes of three second diodes connected to the respective second ends of the three center-tapped primaries; anodes of the three second diodes shorted together and denoted as a second short; a switching device connected between the first short and the second short; three transformer secondaries; anodes of three third diodes connected to the respective three transformer secondaries; cathodes of the three third diodes shorted together as a third short; respective other sides of the three secondaries shorted together as a fourth short; a load capacitor connected between the third short and the fourth short; a load connected in parallel with the load capacitor; a fixed frequency fixed pulse width generator to turn on and off the switching device; wherein the fixed frequency fixed pulse width generator pulse width is varied to control a load voltage.
