AI Technical Summary
In the existing technology, there is a difference between the efficiency simulation model of the motor controller and the actual motor controller circuit, resulting in insufficient simulation accuracy in the low-torque area, affecting the thermal management strategy and the accuracy of vehicle energy consumption prediction.
A circuit simulation model of the motor controller is established, taking into account the imbalance of the three-phase current and the harmonic content in each phase current. The simulation accuracy is improved by adjusting the simulation parameters, including the loss and power calculation models, and the design scheme is optimized to meet the simulation requirements.
The simulation accuracy of motor controller efficiency is improved, especially in the low-torque region, reducing the difference between simulation and measured results and providing more accurate thermal management and energy consumption prediction data.
