Analysis of topology and PWM strategy for a new multiple input and multilevel inverter

In the multi-level inverter with two or more separate DC sources, the cascaded topology is usually used. in this paper, a new two-input multi-level inverter for interfacing with renewable energy resources is developed. The objective of this research is to propose an alternative topology of hybrid cascaded multilevel inverter. The proposed topology can reduce the number of required power switches compared to the traditional cascaded multilevel inverter. And the modified PWM technique is developed to reduce switching losses. PSIM (PowerSim) and Simulink in MATLAB are used to simulate the circuit operation and control signal. The simulation results show that this alternative topology can be applied for interfacing with renewable Energy resources as a hybrid multilevel inverter.
