Abstract

The present invention is capable of reducing a component withstand voltage and stably suppressing higher harmonics. A controller (4) for an active converter (3) for removing higher harmonics from an input current containing the higher harmonics flowing out from a rectification circuit for converting alternating current into direct current, includes: voltage detection sections (11) and (12) for detecting an input voltage and an output voltage of the active converter (3), respectively; a correction value determination section (13) for determining, when the active converter (3) is not in operation, a correction value used for correcting a detection deviation of the output voltage with respect to the input voltage detected by the voltage detection sections (11) and (12); and a control section (14) for correcting, when the active converter (3) is in operation, the output voltage detected by the voltage detection sections (11) and (12) with the correction value, to perform step-up ratio control.
