摘　　要：研究了具有无功功率自动补偿功能的有环流交交变频同步电动机调速系统。与传统的逻辑无环流交交变频器相对比 ,不但消除了变频器对电网无功的冲击 ,而且提高了最大输出电流的频率上限 ,减小了输出脉动。这既改善了系统的运行性能 ,又消除了对电网的污染 ,充分发挥了同步电机交交变频调速系统的优势。To study cycloconverter fed synchronous motor speed adjustable system with circumfluence and automatic reactive power compensation.Contrasted with traditional cycloconverter without logical circumfluence,the new cycloconverter fed drive system not only eliminates reactive power impluse to electric network,but also heightens upper frequency of maximum output current and reduces output ripple current.Advantages of cycloconverter fed drive system have been fully applied,therefore,operation performance of the system is improved and pollution to electric network is eliminated.
