摘　　要：阐述通过搭建样机和加载实验表明,提出的三相电压型PWM整流器及电压和电流双闭环控制策略在伺服压力机的驱动系统中应用良好,PWM整流器动态特性良好,响应快,直流母线输出电压稳定。PWM整流器能在有效回收利用伺服压力机制动能量的同时抑制电网电压波动,可以单位功率因素运行。This paper describes that the proposed three-phase voltage type PWM rectifier and voltage and current dual closed-loop control strategy have been well applied in the drive system of servo presses through the construction of a prototype and loading experiments.The PWM rectifier has good dynamic characteristics,fast response,and stable DC bus output voltage.PWM rectifier can effectively recover and utilize the braking energy of servo press while suppressing voltage fluctuations in the power grid,and can operate at a unit power factor.
