Application of SPMC75F2413A in open-loop V/F control of three-phase AC induction motor: The system input power supply voltage is AC110V/AC220V, which is used by the system after full-wave rectification. The system uses Sunplus\'s SPMC75F2413A to generate the SPWM signal required for VVVF control of AC three-phase asynchronous motors and complete the system control. Mitsubishi\'s intelligent power module PS21865 is used to realize the power drive of the motor. When AC220V is input, the system can drive a maximum load of 1.5KW. The system\'s frequency conversion range is 2Hz~200Hz.
