Single-Phase Step-Up Switched-Capacitor-Based Multilevel Inverter Topology With SHEPWM

Multilevel inverter (MLI) topologies play a crucial role in the dc-ac power conversion due to their high-quality performance and efficiency. This article aims propose new switched-capacitor-based boost multilevel topology (SCMLI). The proposed consists of nine semiconductor switches with one dc voltage source two capacitors, capable generating nine-level output waveform twice gain. With addition switches, can be used for higher voltage-gain applications. Other features include self-voltage balancing parallel operation lower stress across along inherent polarity changing capability. To obtain waveform, selective harmonic elimination pulsewidth modulation technique is applied. In this technique, detrimental low-order harmonics easily regulated eliminated from MLI. compared recently introduced SCMLI considering various parameters set benchmark topology. MLI investigated through experimental results using laboratory prototype setup.
