摘　　要：提出一种新型的内馈斩波串级调速系统,将PWM整流技术引入串级调速系统中,不仅有效提高串级调速系统的功率因数和减少网侧谐波含量,而且排除了逆变颠覆的故障。介绍了电压型PWM整流器的工作原理和控制策略,并通过MATLAB仿真进行了验证。A new type of Feeding chopper cascade adjustable speed system is presented. PWM rectifier technology was leaded into the cascade adjustable speed system, so that it could not only effectively improve power factor of the cascade adjustable speed system and reduce the harmonic content of the network side, and eliminated the fault of the inverter subversion. Presented the working principle and control strategy of voltage source rectifier, and verified by MATLAB simulation.
