Abstract

A circuit configured to, for each of values of output currents output from power conversion devices connected in parallel to one another and driven based on common ON signals applied to the power conversion devices, output a difference between the output current value and a reference value when a polarity of the output current value is positive, and output a difference between an absolute value of the output current value and an absolute value of the reference value when the polarity of the output current value is negative; and a circuit configured to output adjustment time signals each of which indicates an amount of a delay time of a rising timing or a falling timing of the ON signal, according to an output value of the output current difference calculation circuit.
