It makes the output to be a stable AC power source.The system of this paper uses Matlab/Simulink to build and to simulate, and uses DSP to be the center of the digital control. It uses C language to build the software which deal with the returned signals, to achieve the whole voltage close loop control system. The input voltage is 200V DC, the switching frequency is 100kHz, the output voltage is 110V AC.The results of the experiment showed that when the input voltage is 200V DC and different load, it can get a output voltage with 110V AC. The whole efficiency is more than 70%.
