The main circuit faults of the four-quadrant rectifier and the corresponding influences were analyzed and summarized，focusing on the analysis of the voltage and current parameter equations in the pre-charging process of the intermediate DC link，and the estimation method of the converter input current and the intermediate DC link voltage was proposed. The estimated parameters were compared with the actual detection results，and the corresponding fault detection can be carried out by using the performance of different faults in the pre-charging process. Through simulation and experiment，different faults were simulated and analyzed，and the results show that the fault detection method proposed is effective and feasible.
