PROBLEM TO BE SOLVED: To propose a converter controller capable of suppressing the harmonic components of a primary current even when distortion occurs in the primary voltage and the harmonic components are superposed.SOLUTION: A converter device for converting an AC power obtained from a single-phase AC aerial line via a transformer into a DC power, and a control part for controlling the current on the AC side of the converter device so that the voltage on the DC side of the converter device reaches a prescribed value are provided in a converter controller. Based on a voltage value obtained by addition of fundamental wave components and harmonic components of the voltage applied to the AC side of the converter device via the transformer, the control part sets an output voltage of the converter device. |
