Simulation of SEPIC-CHMLI based micro inverter for high step-up voltage conversion

Abstract

Within the photovoltaic power-generation market, the ac PV module has shown obvious growth. This paper proposes an implementation of Single Ended Primary Inductor (SEPIC) converter and cascaded multi level inverter for an AC load using Photovoltaic energy as a source. This paper proposes a converter that employs a continuousconduction- mode SEPIC converter with low reverse-recovery loss. To convert the boosted DC output voltage from PV module into AC, a cascaded multi level inverter with multi carrier pulse width modulation is implemented. An operation principle and a detailed analysis of the proposed converter are presented. A 12V input voltage, (220-230)V output voltage of the proposed converter has been implemented. The simulation work of these SEPIC converter and cascaded multi level inverter fed RL load have been done using MATLAB software
