For improving the defects of the traditional DC-AC system with low power,low efficiency and high loss,a scheme of the improved DC-AC system is presented. The symmetric voltage controlled MOS switch tube push-pull work mode and the scheme that MOS is driven by soft switch tube were adopted instead of mechanical switch(such as relay),triode(BJT) and silicon controlled rectifier(SCR)in the traditional design scheme. The improved circuit system has high stability,high effi-ciency and low loss. The working principle of the circuit is analyzed. The PSpice-simulation software was used to evaluate the fea-sibility of the control circuit. The reliability of the circuit was verified by experiment.
