Title :
A Single-Stage Grid-Connected PV Micro-inverter Based on Interleaved Flyback Converter Topology
Abstract :
Grid-connected photovoltaic (PV) micro-inverters deliver the solar energy from a single PV panel to AC utility. Compared with conventional centralized inverters, micro-inverters have several advantages, such as higher maximum power tracking efficiency, easier installation and longer life-time. In this paper, a single-stage grid-connected micro-inverter based on interleaved fly back converter topology is presented. A prototype with input power rating of 250W and output power rating of 230W/220Vac is constructed and compatible with 60 cell and 72 cell solar modules applications. Experimental results verify the feasibility of the developed micro-inverter which delivers greater energy harvest, higher reliability and more intelligent operation.
