A new reduced switch double boost five-level inverter with Self-Balancing of Capacitor Voltage

Abstract

Abstract This paper proposes a new five-level double boost inverter based on switched capacitor technique. The proposed topology has fewer number of components and has the ability of balancing the voltage across the capacitor. The structure of the proposed topology is very simple and can be easily extended to higher number of voltage levels. The proposed generalised topology for higher gain is presented. This proposed 5-level inverter is compared with the state-of-art topologies to demonstrate the superior performance of the proposed topology. The proposed topology is simulated using MATLAB/Simulink by using the simplified control logic. Further, the power losses are calculated to find the efficiency of the proposed topology. Finally, this topology is tested in laboratory for the performance verification and the results are included.
