For DC-link capacitor used in such fields as flexible and rail transit,the test verification of AC/DC superposition is more in line with the need of actual condition.The focus of how the capacitor manufacturers can utilize existing testing equipment to set up a testing platform for AC/DC superimposed testing is in the isolation protection of AC and DC power sources.On the basis of introducing the principles of AC and DC independent test circuits and AC/DC superimposed test circuits,the parameter selection principles of DC isolation capacitors,AC isolation inductors and discharge resistors are clearly defined.It provides a train of thought and method for setting up a DC-link capacitor AC/DC superimposed test platform for capacitor manufacturers to utilize existing equipment in the factory and minimize equipment costs.
