Title:
TEST SYSTEM AND METHOD FOR POWER CONVERSION APPARATUS, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/011051
Kind Code:
A1
Abstract:
A test system and method for a power conversion apparatus, and a storage medium, belonging to the technical field of aging tests. A power supply grid is connected to an alternating-current end of a first power conversion apparatus, the power supply grid is further connected to an alternating-current end of a second power conversion apparatus, and a direct-current end of the first power conversion apparatus is connected to a direct-current end of the second power conversion apparatus. In this way, a test loop can be formed between the power supply grid, the first power conversion apparatus and the second power conversion apparatus. In the test loop, the first power conversion apparatus and the second power conversion apparatus can serve as both a load and a power supply, such that a direct-current power supply and a load do not need to be additionally provided during testing, thereby saving investment costs and energy consumption. A control unit (3) can control the first power conversion apparatus and the second power conversion apparatus to operate simultaneously in different operating modes, such that an aging test can be performed on the first power conversion apparatus and the second power conversion apparatus at the same time, thereby improving test efficiency.
