摘要
直流电动机因其具有良好的调速和控制性能，仍在许多领域得到广泛的应用。当 前，在直流调速方面，脉宽调制调速技术发展迅速，具有相当广阔的应用前景。本文在 PWM 直 流调速系统设计方面作了一些研究与探索，内容包括 PWM 功率转换电路的设计、控制电路的设 计、保护电路的设计和系统其他部分的设计，及相应的参数计算和元件选择，并应用仿真软件对 设计方案进行了仿真验证。
Direct current （DC） machines are used in a lot offields widely for itsgood speed-regulating and controlling performance. At present, Pulse Width Modulation （PWM） technology develop rapidly and have a bright prospect in DC speedregulating. In this thesis, work was done to research and attempt on designing PWM DC speed-regulating system.lt include the designing of PWM power changer circuit, the designing of controlling circuit and the engineering designing of adjusters. And the designing of other circuits, calculating of system parameters, selecting of system devices are showed too. At last, this projectwas verified with simulation.
