Description: The single-phase sine wave inverter is designed to 12V battery as input sine wave AC output to the standard 36V, 50Hz' s. 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 of the driver chip IR2110 full bridge inverter, using U3990F6 completed SPWM modulation, the output stage is sampled using a current transformer feedback, forming a double feedback loop, increasing the stability of the power in the protection, with multiple output overload protection, short circuit protection, over-load protection functional circuits, and enhance the reliability and security of supply the output AC voltage through AD637 rms converter, and then analog to digital conversion is controlled by the microcontroller STC89C52 final voltage value is displayed on the LCD 12864, forming a good The man-machine interface. The completion of the power good indicators, i
