Abstract:
According to the ground fault detection for high-power converter, it designed a new grounding detection circuit and put forward the corresponding ground judge logic schemes, and analyzed the reasons of grounding voltage fluctuation through calculating and actual measuring to extract the common mode interference parameters of high-power converter combining with the common mode interference model of the converter. Moreover, it set up a grounding detection model of power converter with Matlab. The simulation and experiment results show that the detection strategy can judge the grounding fault of converter effectively.
