A Low Switch Count 13-Level Switched-Capacitor Inverter With Hexad Voltage-Boosting for Renewable Energy Integration

Switched-Capacitor multilevel inverters (SCMLI) are being explored for renewable power applications like solar-PV integration because of their benefits low component count and low-cost factors. This work presents explores a new inverter with hexad voltage-boosting capability. It employs single source produces 13-level waveform by utilizing only fourteen switches, two diodes, four capacitors. The voltage across the capacitors is maintained at desired magnitudes during switching connecting DC in parallel several time locations one operating cycle. topology proposed this compared recent topologies terms capacitors, cost factors (CF). A level-shifted PWM-based algorithm generates circuit switches’ PWM pulses. CF SCMLI found to be 2.461, which lowest among hexad-boosted MLIs. Experimental validation performed on hardware prototype validate various operational conditions load change, modulation index reference frequency change.
