摘要
提出了一种耗散型的PWM变换器拓扑结构,这种结构通过电阻对电机制动能量进行有效快速的处理,防止直流母线电容电压泵生,进而防止造成电机加载的失败。主要针对两种加载模式的过程进行分析,论述在不同加载方式下如何通过控制电流指令实施转矩加载。最终通过仿真验证,证明该变换器结构进行快速转矩跟踪的可行性。
This paper proposes a PWM converter with dissipative structure. Effective rapid disposal of motor braking using resistors is realized to avoid loading failure caused by the rising voltage of capacitance. Based on an a- nalysis of the process of two loading modes, the paper discusses the control on the load of torque by current command in different loading modes. Simulation results prove the feasibility of the converter structure for fast torque tracking.
