| 摘 要： | 从能量传递方向角度,对比分析可逆直流桥式PWM调速系统和可逆直流V-M调速系统四象限运行时功率器件和电机的状态。首先独立分析两种系统的直流电源主电路形式和四象限运行状况;之后对比给出不同状态时两类系统功率器件的对应关系,给出直流PWM变换器的整流和逆变状态;最后利用正向轻载运行状态对结果进行验证,得到的结论有利于教学过程中学生对两类系统的深入理解。

| Abstract: | From the view of direction of energy transfer,the state ofthe power device and the motor in the four quadrant operation of two-type reversible DC speed regulating systems,the reversible DC bri-dge PWM system and the reversible DC V-M system,is compared and analyzed.Firstly,analyze the main power circuit forms and thefour quadrant running status of the above two kinds system indepen-dently.Then give the corresponding relationship between them in different states,and define the rectification and inverter of the DCPWM converter.Finally,test the above results by analyzing the posi-tive light load running state.The conclusion is helpful for students to understand the two kinds of systems in teaching process. |
