“…In order to simulate the shaft current path generated by the dynamometer motor, the excitation of the current source is set on the axial surface of the output shaft of the dynamometer motor with an amplitude of 1A, and the direction is along one side of the anechoic chamber [14]. Set up three axial current simulation observation points, which are located at the shaft head of the shaft through the wall outside the semianechoic chamber (observation point A), the shaft head of the shaft through the wall inside the anechoic chamber (observation point B), and the position of the test piece installed inside the anechoic chamber (observation point C).…”

In order to solve the problem of high-amplitude and high-frequency interference generated by the electric drive system of new energy vehicles, the author proposes a closed-loop research method for on-load electromagnetic compatibility testing and simulation for electric drive systems of new energy vehicles. The method includes EMC design of the electric drive system on-load test equipment, establishment of a conducted EMI simulation platform for the electric drive system under load conditions, and optimization of the conducted EMI performance of the electric drive system based on key parameters and PWM control. Experimental results show that if the parasitic inductance of the IGBT gate increases, the conducted emission level in the frequency range of 2∼30 MHz will increase, and there is basically no change at the low frequency, and the position of each resonance point shifts to the relatively low frequency. The experiment was replaced with the DPWM3 modulation mode, and the conducted emission amplitude was reduced by about 2 dBμV in the range of 200 kHz∼2 MHz, and there was basically no change on the whole. Conclusion. It is proved that the electromagnetic compatibility closed-loop development technology of the electric drive system of new energy vehicles under load conditions can meet the development needs of new energy vehicles in the environment where energy problems and air pollution problems are becoming more and more serious.
