Abstract :
Introduced in great detail about the principle of main circuit, sampling circuit, control circuit, drive circuit and protect circuit. Then the specific implementation steps of photovoltaic inverter system were given which based on TI company´s digital signal processor (DSP)TMS320F2812. Described the method of selecting components. The DC/DC and DC/AC two steps grid-connected inverter is proposed based on the characteristic of the invert and photovoltaic. DC/DC and DC-AC are analyzed elaborately and respectively. Proposed a set of new strategies. In the converter of DC-DC, Boost circuit is used for modulating the output of photovoltaic array and tracking the maximum power point of photovoltaic system.
