Abstract
A multi-converter power supply system includes a plurality of cell converters, a common node to which an individual output terminal of each of the plurality of cell converters is connected, a current waveform signal generation circuit that generates a current waveform signal corresponding to a current waveform flowing through an individual inductor, a current average signal generation circuit that generates a current average signal by averaging temporal changes that the current waveform signal has in a switching period of a switching control circuit, and an instrumentation amplifier that receives input of a current common signal obtained from the common node and the current average signal and that generates an individual current feedback signal to be fed back to the switching control circuit.
