摘　　要：提出将PWM整流技术引入转子侧斩波串级调速系统中,PWM整流器工作于逆变状态回馈转差功率,不仅可以提高串级调速系统的功率因数,还可以减少网侧的谐波含量。在Matlab/Simulink环境下给出了基于PWM整流技术的斩波串级调速系统的仿真模型,最后通过仿真实验验证了控制方案的正确性。A rotor-side chop cascade adjustable speed system based on PWM rectifier was proposed.The PWM rectifier worked on inverter condition and returns slip power of the rotor;this could not only improve the power factor of the system,but also reduce harmonic content of net-side.In Matlab/Simulink,the simulation model of chop cascade adjustable speed system was established.The reasonability and validity were testified by the coincidence of the simulation and experimentation results and theory analysis.
