Based on ARMkernel microcontroller and IPM(Intelligent Power Module)and by use of SVPWM(Space voltage Vector Pulse Width Modulation)and vector control method,this paper introduces a variable frequency speed control system for the three-phase asynchronous motor.In view of energy loss of regenerative brake occurring during quick startup and brake of the general-purpose inverter and frequent normal and reverse speed control,we add a grid device for inversion feedback of the regenerative braking energy.Detailed software and hardware design is shown and implemented.The experiment result shows that the system has a high control precision and good real-time performance.It also allows that the inverter can operate in four quadrants,producing remarkable energy-saving effect.
