【 摘 要 】

This paper designs a sine wave inverter that converts 12V DC into 220V/50Hz AC. In the DC/DC converter circuit, the push-pull circuit is used for boosting. The pulse width modulator SG3525 control chip is selected. The MOS tube provides the drive signal modulation wave, first boosts the 12V DC voltage to 400V; then designs the full-bridge DC/AC converter circuit, selects the control circuit based on the SPWM dedicated chip EG8010 and the drive circuit based on the IR2110S driver chip. Finally, according to the hardware circuit and parameter design, the simulation of the design scheme is carried out, and the feasibility of the design scheme of the sine wave inverter is verified.
