Analysis and Implementation of Switched Capacitor-based Multi-Level Inverter for Electric Vehicles Applications

Significant interest has been shown in switched capacitor (SC)-based multi-level inverters (MLIs), which decrease the need for a DC supply and enhance power quality. The common issues with SC-MLIs include an uneven distribution of conducting paths, increased voltage drop across capacitors, sum all inverter link voltages highest rated switches, higher total standing (TSV). purpose this paper is to create SC-MLI less components order maintain constant obtain gain fewer parts, routes, lower TSV, more affordable effective inverter. structure MLI created by cascade interconnection between number SC cells. A single input multiple output (SIMO) converter boosts DC-link over stable solar panels using modified perturb observe (P&O) method. Additionally, switches conduction path 50 % operating at normal frequency guarantee overall loss proposed network. benefits recommended are made clear comparing them 17-level MLIs terms elements, stress, gain, cost factor. Detailed experimental results under various transient conditions show that prototype operationally viable. harmonic distortion (THD) found be identical than 5 %, meets IEEE standards.
