摘　　要：根据直流回路的结构特点,将直流回路分成两部分进行分析,分别给出稳态时整流直流回路电压电流的计算公式和逆变直流回路电压电流的计算公式,推导出直流回路中电流与调速系统各个参数的关系。由直流回路电压电流计算式,进而推出内反馈斩波串级调速系统的机械特性曲线;并且分析了直流回路中各个电抗器的作用以及对调速系统机械特性的影响。The AC-DC-AC circuit was divided into two parts based on its structural charateristics,that is,rectifier and inverter. Voltage current calculation equations of the two were presented respectively. Relations between the current and the various parameters in speed control system were induced. With the calculation equations, the mechanical characteristic wave was calculated for the inner feedback chopping wave cascade speed control system. The effects of reactors and their influences on mechanical characteristics in speed control system were further discussed.
