摘　　要：针对应用于矿山风机、水泵等场合的高压大功率软起动器智能优化控制问题,依据数字频率合成技术,利用现场可编程门阵列(FPGA)直接实现载波移相SPWM(CPS-SPWM)脉冲发生器的设计,并加入异步电机恒压频比控制策略,使得级联型多电平逆变器控制电路实现全数字化控制。Aiming at the intelligent optimization problem of high voltage and high power soft starter used in mine fan and water pump.A pulse generator with carrier phase-shifted SPWM was designed by using field programmable gate array（FPGA）and constant voltage ratio control strategy of asynchronous motor.The cascaded multi-level inverter achieved fully digital control.
