| 摘 要： | 研究了三相半波可控整流和三相桥式全控整流直流电动机调速系统主回路临界电感量L_(lx)和滤波电感量L_(md)的计算问题,提出以限制连续整流电流i_d在谷点以上部分的平均值(也可定义为i_d的脉动幅值)作为滤波指标,从而使L_(lx)和L_(md)的计算公式达到统一,分析了回路电阻对L_(lx)和L_(md)计算的影响。

| Abstract: | Discusses computation of the critical inductance L_(1x) and the filtering inductance L_(md) both in 3-phase half cycle controllable rectified circuits and 3-phase fully controllable bridges with thyristors for DC motor dirve.A Filtering index is presented by confining the mean value of the difference of continuous rectified current and its valley point value,hence the computing formula for L_(1x) and L_(md) can be unified.The influence of the circuit resistance on the computations of L_(1x) and L_(md) is also investigated. |
