<p>PROBLEM TO BE SOLVED: To provide a switching-element control circuit that allows achieving stabilization of a feedback loop.SOLUTION: A switching-element control circuit, which converts an input voltage into a predetermined voltage by controlling a first switching element SW1 and a second switching element SW2 to output the predetermined voltage to an immitance converter M1, includes: a comparison error circuit 12 generating an error voltage on the basis of the difference between an output voltage according to an output current of the immitance converter M1 and a reference voltage; a PWM signal generating circuit 13 generating a PWM signal by comparing the error voltage with a phase compensation slope voltage; and a phase compensation circuit 31 compensating phase delay of the output voltage. The PWM signal generating circuit 13 generates the PWM signal by comparing the phase compensation slope voltage to which a voltage outputted by the phase compensation circuit 31 is added with the reference voltage.</p> |
