TEST SYSTEM AND METHOD FOR POWER CONVERSION DEVICES, ELECTRONIC DEVICE, AND STORAGE MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18310065 titled 'TEST SYSTEM AND METHOD FOR POWER CONVERSION DEVICES, ELECTRONIC DEVICE, AND STORAGE MEDIUM

Simplified Explanation

The patent application describes a system and method for testing power conversion devices.

  • The system connects a power supply grid to the AC terminals of two power conversion devices.
  • The DC terminal of the first power conversion device is connected to the DC terminal of the second power conversion device.
  • This creates a test loop where the power supply grid, first power conversion device, and second power conversion device form a circuit.
  • The first power conversion device acts as a load, while the second power conversion device acts as a power source.
  • This eliminates the need for additional DC power supply and load during testing.


Original Abstract Submitted

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.
