摘　　要：变频器控制柜应具备自动软起动和手动降压起动功能。若用体积小、成本低的星三角起动器作手动降压起动 ,它与电动机的联接是星形联接 ,而变频器的输出与电动机的联接是三角形联接。通过对星三角起动器控制电路原理的分析 ,并对控制电路稍作改动 。Inverter control board should have automatic control soft start function and manual reduce voltage start function. If Y delta starter which is small and cheaper is chosen, and its Y connection is incoordinate with the delta connection of inverter, how do make the two connections coordination? Analysising the principle of Y delta starter control circuit and making a litter improvement of the control circuit, the two connections can be operated in a coodinated way.
