Grid-Connected Solar Microinverter Study and Design Using a dsPIC Digital Signal Controller

Abstract:

Article Preview

An interleaved flyback converter using a dsPIC digital signal controller is researched and designed, regarding to photovoltaic (PV) grid-connected micro inverter’s characteristics, the system structure and control principles is studied, and a new method combining Constant Voltage (CV) and Perturb and Observe(P&O) to track the Maximum Power Point (MPP) is applied. The prototype experiments verify that the inverter can better realize the most power tracing and island detection function, at the same time reduce the current output ripple, lower its THD.
