摘要
单相电压型PWM整流器用于电力机车辅助变流器的前端时,由于机车运行环境的恶劣和整流器本身的强非线性等特点给控制造成了很大的困难,而滑模变结构控制具有鲁棒性强、可靠性高的优点。因此本文提出了一种基于滑模变结构的单相电压型PWM整流器的控制方法。仿真结果表明,这种控制方法具有良好的性能。
Auxiliary converter of electric locomotives in which single-phase voltage source PWM rectifier is adopted as the front can hardly obtain good performance in operation due to the bad condition and the strong nonlinear characteristic of VSR,So a strategy which is used in single-phase voltage source PWM rectifier based on sliding mode was proposed.Simulation results show that control strategy have good performanee.
