Claim:
1. A power circuit comprising: 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 a 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, wherein the control signal generator compares a comparison value with first and second carrier signals to generate the first and second control signals, the frequency converter converts frequencies of the first and second carrier signals to thereby convert the frequencies of the first and second control signals, and the phase shifter shifts a phase of the second carrier signal to change the phase of the second control signal.
