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, and a first instrumentation amplifier that receives input of an individual output voltage signal obtained from the individual output terminal and the current waveform signal and that outputs a signal for comparison with a current common signal shared by a plurality of switching control circuits. The current waveform signal and the individual output voltage signal that are input to the first instrumentation amplifier are formed with reference to a potential of the common node.
