Medium-voltage three-level high-power test system meeting multiple working conditions

The utility model relates to a medium-voltage three-level high-power test system meeting multiple working conditions, which comprises an inlet wire transformer, a rectifier module group, a direct-current bus capacitor group, a test board controller, an accompanying test power unit, a load reactor and a test board controller networking system, the inlet wire transformer, the rectifier module group and the direct current bus capacitor group are sequentially connected and output a direct current bus, the accompanying test power unit is connected with a tested object through a load reactor and is also connected to the direct current bus, and the testboard controller and the testboard controller networking system are used for testing different tested objects. The medium-voltage three-level power unit test system can complete the test of a single medium-voltage three-level power unit, two medium-voltage three-level power units and a medium-voltage three-level inversion or rectification system of any brand, improves
