Seven Level Single Source Switched-Capacitor Multilevel Inverter implemented with NLC and Level Shift PWM Technique

This research work presents a single source Switched Capacitor Multilevel Inverter (SCMLI) topology having a capability to generate 7 discrete voltage levels with a voltage gain of 3. To unveil the superiority of the presented topology in terms of component count, diodes, and capacitors, comprehensive comparison is done with other existing SCMLI topologies. The proposed topology has 10 switches and 2 floating capacitors which are charged to Vdc and 2Vdc respectively. The presented topology has been verified in a real-time environment using Opal-RT 4510, and results for different parameters are presented in this paper. The topology has been validated using real-time simulations and the MATLAB simulation results are found to be similar to real-time simulation results.
