1、电力电子技术课程设计说明书单相交流调压电路的设计院、部：电气与信息工程学院学生姓名：指导教师：职称专业：自动化班级：完成时间：29摘要交流调压电路广泛用于灯光控制（如调光灯和舞台灯光控制）及异步电动机的软启动，也用于异步电动机调速。在电力系统中，这种电路还常用于对无功功率的连续调节。此外，在高电压小电流或低电压大电流直流电源中，也常采用交流调压电路调节变压器一次电压。在这些电源中如采用晶闸管相控整流电路，高电压小电流可控直流电源就需要很多晶闸管串联；同样，低电压大电流直流电源需要很多晶闸管并联。这都是十分不合理的。采用交流调压电路在变压器一次侧调压，其电压、电流值都比较适中，在变压器二次侧
2、只要用二极管整流就这样的电路体积小、成本低、易于设计制造。单相交流调压电路是对单相交流电的电压进行调节的电路。用在电热制、交流电动机速度控制、灯光控制和交流稳压器等合。与自耦变压器调压方法相比，交流调压电路控制简便，调节速度快，装置的重量轻、体积小，有色金属耗也少关键词：交流；调压；电动机调速；电力系统；变压器；ABSTRACT29Acvoltagecircuitiswidelyusedinlightingcontrol(suchasdimmerandstagelightingcontrol)andasynchronousmotor,alsousedinthesoftstart-upind
