Provided is a device for testing the performance of a power conversion device, wherein the performance of a power conversion device can be tested while varying topology using a single device. The performance testing device comprises: a first converter part including multiple first switching elements and connected to a power source; a second converter part including multiple second switching elements; a load part connected between the first converter part and the second converter part; and a control part for adjusting a voltage applied to the load part and a current flowing in the load part by controlling the first converter part and the second converter part. The control part adjusts currents flowing in the first switching elements and the second switching elements by changing a phase difference value between the voltage applied to the load part from the second converter part and the current flowing in the load part. |
