A Novel 13L SC-Based Inverter with Reduced Capacitor Spike Current and High-Gain

Abstract

In this article, a 13L inverter is suggested if you want to get a high level of efficiency and more voltage gain. The suggested SC-based inverter architecture needs 13 (IGBTs or MOSFETs), 2 diodes, 3 capacitors, resonant inductors, and a source of DC power. Resonant inductors are added to the circuit to reduce the spike current from the capacitor and source voltage. Moreover, the capacitors are self-balanced throughout the whole range of modulation index. A full analysis of the recently developed topologies is done in terms of the number of sources, switches, drivers, total standing voltage (TSV), gain, and cost function. This is done to show conclusively that the proposed topology offers better performance. Several simulation and experiment results are shown to show that the suggested topologies are possible and useful.
