A Grid-Connected, PV-Interfaced Inverter with Coupled Inductor–Based Dual Input 3P3L-ZSI

CODEN: JTEVAB

Abstract

This article presents a dual-input impedance network derived three-phase three-level (3P3L) Z-source inverter (ZSI)–based inverter to transfer the power generated on the photovoltaic (PV) system to grid. The PV power generation system has become a most popular renewable power generation system because of the abundant availability of solar energy and the growth of the modern power electronics converters. The ZSI provides single-stage power conversion for dc–ac conversion with a regulated voltage at the output. The proposed inverter is constructed with an Inductor-Capacitor-Capacitor-Transformer (LCCT)-derived impedance network to extend the voltage boosting gain and efficiency with small duty ratio. The boosting gain, efficiency, and power transfer capability of the proposed topology are demonstrated by several case studies. The experimental results of the proposed 3P3L-ZSI–based inverter with dual-input voltage source are presented to validate the simulated results.
