In view of the disadvantages of some complex industrial installation environment and saving cost in general inverter, a simple vector control inverter which based on STM32 is proposed. The design of hardware and software were given. The hardware optimized design of it’s structure, so it more smaller、lighter and easy installation. The principle of SVPWM modulation and it’s realized on STM32 were described. Thus it combine with fieldbus technology can bring flexible and precise control in disperse system. The experimental result show that the system has less harmonic ware,real time control function,energysaving and reliable.
