Abstract
System and method for testing power conversion devices are provided. A power supply grid is connected to an AC terminal of a first power conversion device, the power supply grid is also connected to an AC terminal of the second power conversion device, and a DC terminal of the first power conversion device is connected to a DC terminal of the second power conversion device. In this way, a test loop is formed by the power supply grid, the first power conversion device and the second power conversion device. In this test loop, the first power conversion device and the second power conversion device act as a load and a power source, so no additional DC power supply and load are required during the test.
