Abstract
A multiphase power supply has an input terminal, an output terminal, a plurality of transformers, a plurality of switching circuits, and a control circuit. Secondary windings of the plurality of transformers are coupled in series with a compensation inductor. The plurality of switching circuits are coupled in parallel between the input terminal and the output terminal. Each of the plurality of switching circuits is coupled to the output terminal via a primary winding of a corresponding transformer. The control circuit senses an average current flowing through the plurality of switching circuits and a current flowing through the compensation inductor respectively, and corrects a sensing result of the average current based on the current flowing through the compensation inductor. The control circuit further provides a plurality of pulse width modulation signals based on the output voltage and the corrected sensing result to control the plurality of switching circuits.
