Abstract
A power circuit includes: first and second switching circuits coupled in parallel between an input terminal and an output terminal; a control signal generator that performs an ON/OFF control of the first and second switching circuits individually and generates a first control signal and a second control signal having different phases; a frequency converter that converts a frequency of the first control signal after converting a frequency of the second control signal; and a phase shifter that shifts the phase of the second control signal when a first interrupt is introduced as the first control signal is turned ON after the frequency converter has converted the frequency of the second control signal.
