Abstract
An electric power conversion apparatus according the present disclosure includes: voltage detectors which detect the voltages of both bridge circuits, and a control device which controls the semiconductor switching elements of both bridge circuits. The control device includes a phase difference operation part which calculates a phase difference between the output of the first bridge circuit and the output of the second bridge circuit, based on the voltage values of both bridge circuits which are detected by the voltage detectors and an electric power command value; a compensation amount operation part which calculates a compensation amount which compensates an error due to the phase difference; and a PWM signal generation part which generates gate signals of the semiconductor switching elements, from a first operation result of the phase difference operation part and a second operation result of the compensation amount operation part.
