Patent ID: 7071662

Claim:
A synchronized parallel running power converter, controlled by a single-phase pulse-width modulator; said single-phase pulse-width modulator having a first pulse output port and a second pulse output port for pulse outputs, said power converter comprising: a first power converter, having a first pulse input port, a second pulse input port and a current output port; said first pulse input port is coupled to said first pulse output port of said single-phase pulse-width modulator; said second pulse input port is coupled to said second pulse output port of said single-phase pulse-width modulator; and a second power converter, having a first pulse input port, a second pulse input port and a current output port; said first pulse input port is coupled to said first pulse output port of said single-phase pulse-width modulator; said second pulse input port is coupled to said second pulse output port of said single-phase pulse-width modulator; wherein said power converters are synchronized by controlling said single-phase pulse-width modulator thereby equalizing the output currents from said current output ports.
