Simulation of Self Balanced Switched Capacitor Based Thirteen Level Inverter

The designing of the thirteen level inverter based on switched capacitors with the ability of self-balancing is presented in this article. The proposed inverter converts the low DC voltage into high AC voltage by connecting the switched capacitors in series-parallel. The Phase Disposition modulation scheme with Multi-carrier is developed to generate the switching pulses. The capacitor voltages are balanced itself which improves the performance of the system. As opposite to existing switched-capacitor based inverters, the proposed inverters do not have an H-bridge circuit and the voltage stress of the switches is not exceeded to the supply voltage. The voltage ratings of each mode of operation is realized in mathematically and the harmonic distortions are also observed at different modulation indices. The MATLAB/SIMULINK is used to simulate the inverter and observed the advantages of low peak inverse voltage, total standing voltage, high conversion ability, and high boosting capability.
