Simulation Design of Inverter in Solar Photovoltaic System Based on MCU

A used solar power generation system based on the control of the microcontroller single-phase full-bridge inverter is designed in this paper. Inverter main circuit for the full-bridge inverter structure is formed by four IRF830A with SPWM frequency modulation work. After analysis and comparison, area, and so follow the example set by SPWM wave to calculate the duty cycle and design controller. AT89S51 as a chip to control, based on the Proteus and KeilC integrated development environment for system software design, software debugging of hardware circuits finally, the results show that all parts of indicators meet the requirements.
