Abstract

The push-pull power boost and full-bridge inverter levels change in the control circuit, the first-stage booster circuit using SG3525 chip push-pull control, closed loop feedback; inverter part EG8010 complete SPWM modulation driver chip IR2110 be full-bridge inverter; after level output is sampled using a current transformer feedback, a double feedback loop, increasing the stability of the power; on protection, with output overload, short circuit protection, overcurrent protection, load protection and multiple protection features circuit, and enhance the reliability and security of supply; inverter power dependence of the clean, efficient, renewable solar energy resources, the use of solar photovoltaic cells lithium battery charging plate board, pre-24V lithium battery voltage through DC-DC conversion is about 400V DC high voltage, after the class by a full-bridge DC-AC circuit 400V voltage controlled by SPWM inverter is 220V, 50Hz AC sine standards for the use of electrical appliances.
