This paper presents simulation implementation of different types of loads inr high-gain single-stage boosting inverter (SSBI) for photovoltaic applications. The two-stage micro inverter first performs dc to dc voltage step up and then converts dc to ac, whereas the single-stage topology has to perform the dc to dc voltage step up, and the dc to a c inversion functions all in one stage. The single stage boosting inverter system employs a Tapped Inductor to attain high-input voltage step up and, thus, allows operation from low dc input. The traditional two-stage approach is costly and has complex topology whereas the Single Stage Boosting Inverter has a simpler topology and a lower component count. The Single Stage Boosting Inverter can achieve high dc input voltage boosting, good dc–ac power decoupling, good quality of ac output waveform, and good conversion efficiency. The simulation results for linear R (Resistive) and RL (Inductive) loads as well as nonlinear RC and nonlinear resistor and saturable inductor loads are shown in this paper.
