Abstract: This paper designed a new type of photovoltaic micro-inverter system, giving the hardware structure and software design. The main control section adopted the redundant structure, being able to switch to the spare chip’s running at the time of the failure of main chip. The testing result of 225 W experiment prototype shows that the system has stable control performance, high efficiency, simple circuit and low cost with application value of engineering.
Key words: photovoltaic micro-inverter; redundant system; maximum power point tracking; islanding detection
