PROBLEM TO BE SOLVED: To provide a rectification circuit device and a control circuit for the same that can perform a rectification operation in which power line harmonics current is stabilized under a condition that loss of a rectification circuit is not increased due to extreme increase of a boosting rate.SOLUTION: In a rectification circuit device for making a semiconductor switch 104 perform a chopping operation to short-circuit or open the output terminal of an AC power source 1 through a reactor, rectifying an AC voltage supplied from a single phase AC power source 1 through a reactor 102 to a DC voltage and supplying the DC voltage to a load, a control circuit 100 controls the chopping of the semiconductor switch 104 so that the waveform of detected current becomes a target current waveform, and controls the amplitude of the target current waveform so that the detected DC voltage becomes a predetermined target DC voltage. The target DC voltage is controlled so that an idle period or non-idle period is equal to a target value when there is no pulsation, and the target DC control voltage is controlled so that the difference during the idle period or the non-idle period is not more than a determination value during pulsation. |
