High-Efficiency Switched-Capacitor Multilevel Inverter Topology With Lower Number of Switching Components
Objective
The main objective is to develop a high-efficiency switched-capacitor multilevel inverter topology with a lower number of switching components, aimed at achieving high voltage gain and high-quality stepped AC output from low-voltage DC sources, while significantly reducing the number of power switches, gate drivers, and passive elements.
Abstract
In this project, to increase the voltage from sources such as photovoltaic (PV) systems, fuel cells, and battery storage devices, a boost conversion is required. The proposed switched capacitor multilevel inverter (SCMLI) topology incorporates nine power semiconductor switches, a dual DC voltage source, and a single capacitor, capable of generating a nine-level output voltage with dual voltage gain. Additional features of the proposed SCMLI topology include self-voltage balancing of the capacitor without the need for any additional circuitry, reduced voltage stress across the switches, and an inherent capability for polarity reversal. Furthermore, the topology eliminates the need for bulky components like inductors, leading to a compact and cost-effective design. The performance of the proposed SCMLI is investigated through numerous simulation results under various operating conditions using MATLAB Software.
