Solar Powered Nine-Level Inverter With Reduced Switches

Abstract

A DC / DC converter of nine levels for power generation using solar system is presented in this paper. The configuration consists of dc-dc boost converter and a transformer is used for conversion of output voltage into three voltage sources. The capacitor selection circuit, full bridge converter is used in circuit. The stages of conversion are three independent voltage sources into dc voltage with four levels then to nine levels AC voltage. The utility voltage is in phase with the current generated in the above mentioned conversion. The performances of PV array are improved by using MPPT controller to track maximum power. The simulated results are validated and tested with developed prototype.
