Simulation of switched capacitor inverter topology with boost facility

Abstract

Simulation of switched capacitor inverter topology with boost facility is presented in this paper. The main merits of this inverter topology with boos facility are highly adaptable for Photo Voltaic (PV) applications. The inverter is capable of boosting up low voltage DC into high voltage DC and then invert it to the required voltage level with a single stage. The switched capacitor inverter has a special extended structure, which minimizes the number of components and devices when compared to the other inverter is switched by the means of level shifting carrier based Pulse Width Modulation (PWM) technique. Further, some of the switches in the topology operate in the low frequency and this resulted in a reduction in switching losses thereby increasing the efficiency. This maintains the capacitor voltages at a balanced level. The simulation results are verified through MATLAB/Simulink.
