Abstract

Grid-connected photovoltaic power system consists of simulation of solar modules, inverter main circuit, driver circuit, maximum power point tracking circuit, the MCU control display system and the FPGA, protecting circuit. Inverter main circuit is the analog output of solar modules through the inverter main circuit DC into AC power reverse, and then through the filter, the output stable AC; one FPGA processor is SPWM signal generated by the drive circuit driving inverter main circuit switch, SCM complete solar photovoltaic maximum power tracking device calculates and displays; protection circuit is mainly done when the input voltage and output over-current system work to stop in time when the system protection.
