Description
Summary:In the real world, the AC load is more common than the DC load, so many PV power systems have an inverter. Although has various structure type inverters, but Speaking of the simulation research, single-phase inverters in all structures are the same. The stand-alone inverter model has established in this paper, the open-loop and close-loop simulation results are shown. The simulation results indicate that the capacitor value parallel PV has an important influence on MPP tracing precision. In order to reach high MPP tracing precision, small ripple peak amplitude on capacitor is necessary, and usually this means a capacitor with large capacitance. The expression of ripple peak amplitude on capacitor is derived.
