Introduction was made to the average value closed loop control principle. MATLAB software was used to carry out simulation analysis for control strategy. The DSP was taken as an experimental platform to carry out experiment and verifi cation for hardware and software of the system. The result shows that this plan can assure stable inverter output with good dynamic performance and low cost, meeting the need of normal site. Key words: sinusoidal pulse width modulation; digital signal processor; dual-closed loops control.
