摘要

基于有限元/差分法的高效电子换向永磁电机(ECPM)驱动器的设计，以及随之而来的微分方程的SPICE求解。永磁电机模型包括电机等效电路中负载相关分量的计算(如感应电压和电感)。介绍了一种反映反向恢复电流现象的新型SPICE MOSFET模型，该模型对设计工作在脉宽调制(PWM)模式下的变速驱动器具有重要意义。模型计算结果与实测结果进行了比较。由于ecpm在重量轻的情况下具有固有的高效率，因此可以很好地用于车辆推进，因此在此类应用中需要具有非常高的输出功率重量比

Modeling and simulation of an electronically commutated permanent-magnet drive system using SPICE

The design of high-efficiency, electronically commutated, permanent magnet machine (ECPM) drives based on the finite element/difference method, and the solution of the ensuing differential equations with SPICE. The permanent magnet motor model includes the computation of load-dependent components of the motor equivalent circuit (e.g. induced voltages and inductances). A novel SPICE MOSFET model reflecting the reverse-recovery current phenomenon-which is very important for the design of variable speed drives operating in pulse-width-modulated (PWM) mode-is introduced. Results of this model are compared with measurements. Since ECPMs lend themselves well to vehicle propulsion due to their inherent high efficiencies at light weight, it is desirable to have a very high output-power-to-weight ratio for such applications.<>
