Performance Analysis of Single Phase Multilevel Inverter Using dsPIC30F2010 Microcontroller

Abstract

This paper presents a single phase multilevel inverter (MLI) topology for 7, 9, 11, 13 and 15 level. MATLAB simulation of proposed topology is carried out by taking R and RL load for different levels. Total Harmonic Distortion (THD) in the output voltage of MLI is evaluated and presented in the paper. To validate the proposed topology hardware implementation is also done using commercially available microcontroller (dsPIC30F2010). The proposed topology provides less THD so becomes an attractive solution for PV based inverters and can be suitable for stand-alone applications like PV fed water pump used in agriculture, multi-story buildings or industries.
