摘　　要：为解决自耦降压存在的电流二次冲击问题,提出自耦磁控(ATMC)软起动方法。该方法将降压技术与调压技术相结合,充分利用自耦降压起动方式从电网吸收电流小及磁控调压方式起动电流平滑的优势,具有起动电流小、起动过程平滑的优点。介绍了ATMC软起动器的拓扑结构,分析了该软起动器实现电流平滑调节的原理,并进行仿真和试验,结果均表明ATMC软起动器起动性能良好,具有较好的应用前景。In order to deal with the current secondary impact issue of auto-transformer buck method, a new soft start method based on auto-transformer and magnetic control（ATMC） is proposed.The new method has dual characteristics of step-down of auto-transformer and regulation voltage of magnetic control reactor, it can further reduce start current absorbed from power grid and start current is adjusted smoothly.Topology is established and the start current adjust- ment principle is analyzed.The simulation and experimental results show that the soft starter has excellent starting performances and application prospects.
