Abstract
Aspects of the invention can provide a control method of a power converter that is capable of preventing increase of electromagnetic noise that are caused by simultaneous change of the states of power semiconductor switching elements of the power converter. State changes of ON/OFF pulses that are input to power semiconductor switching elements are detected, and, when the timings of the state changes of any two of the ON/OFF pulses match each other, the state change of either one of the ON/OFF pulses, of which state changes match each other, is delayed.
