Power Supply and Power Supply Method with Circulation Current Compensation

Abstract

A power supply comprises an inverter leg adapted to generate a first pulse width modulation signal by modulating an input signal, a phase shifter, which is adapted to generate a provisional second pulse width modulation signal by phase shifting a signal from which the first pulse width modulation signal is derived, a compensator, which is adapted to determine a second pulse width modulation signal from the provisional second pulse width modulation signal and add a compensation signal during the generating of the second pulse width modulation signal, and a coupled inductor, which is adapted to combine the first pulse width modulation signal and the second pulse width modulation signal to form the output signal.
