Abstract

For the high voltage safety of electric drive system, an online insulation detection device is designed in this paper. Based on the influence analysis of common mode interference during the electric drive system operation, a continuous zero-vector insulation resistance detection method is proposed to extract insulation voltage online to solve the problem that the traditional insulation resistance detection method fails to monitor the insulation performance due to electromagnetic interference. The proposed method can implement the detection of insulation performance between the high voltage circuit and the car body in static and dynamic situations. The experimental results demonstrate that this method has anti-interference ability and high detection accuracy, which plays an important role in ensuring the high voltage safety of electric drive system.
