Verication Method of Dynamometer Applied to Electromagnetic Compatibility Testing

The electric drive system replaces the internal combustion engine and becomes the power source of new energy vehicles. The electromagnetic compatibility of motor and its controller under load conditions will affect the stability of the electric drive system and the reliability of the vehicle. The electromagnetic compatibility dynamometer that does not affect the performance of the semi-anechoic chamber is the key to realize loading test of the motor. A verification scheme for measuring the applicability of electromagnetic compatibility dynamometer is designed, and a standard loading verification method is proposed. The verification results show that the scheme has good performance in the verification of the suitability of electromagnetic compatibility dynamometer, and provides a powerful reference for laboratory performance verification.
