摘　　要：介绍了一种基于DSP控制的大功率三相EPS逆变电源系统。该系统运行在三相负载不平衡时,能保证三相输出电压完全对称。同时,针对电动机负载的工作特点,提出了一种简单实用的抗瞬间冲击性大电流的控制方式,实现了电动机负载的稳定启动和可靠工作。A three-phase EPS inverter system is introduced, which is based on DSP. When it operates at the most unbalance situation, it can ensure three-phase output voltage symmetrically. Meanwhile, considering the operating characteristics of motor loads, a simple practical control method to resist instantaneous surge current is presented so that the motor load can startup stably and operate reliably.
