PROBLEM TO BE SOLVED: To provide a control circuit that is capable of achieving high-speed and highly precise control and processing with linearity and time invariance with a simple configuration.SOLUTION: A control circuit 7 includes: a current controller 74 that processes a deviation signal between a single-phase current signal I and a current target value with a transfer function G(s) and generates a correction value signal, and a PWM signal generation section 77 that generates a PWM signal on the basis of the correction value signal. When a transfer function indicating predetermined control processing is taken as F(s), an angular frequency of a fundamental wave of single-phase AC is taken as ωand an imaginary unit is taken as j, a transfer function G(s) is as expressed by the following Formula 1: G(s)=F(s+jω)+F(s-jω)/2. |
