Electromagnetic Compatibility and Better Harmonic Performance with Seven Level CHB Converter Based PV-Battery Hybrid System

A. S. S. Veerendra Babu ^[2] | G. Kiran Kumar ^[4]

Abstract: The objective of this paper is to develop for improve electromagnetic compatibility (EMC) and better harmonic performance, with help of seven level CHB Phase shifted PWM technique inverter used for PV-battery hybrid system which makes the irregular PV power smoother and also limits the grid current under grid voltage dips. Proposed configuration which different from the conventional configuration where the PV and the battery inverters are paralleled on the grid side, the proposed seven level CHB based hybrid system connects the AC sides of the PV inverter and the battery inverter in cascade Compare to proposed seven level hybrid system THD is 21.58 % where as conventional parallel inverter system THD is 52.39 %. The seven level inverter output voltages, harmonic performance of grid current and THD is available by using simulation of MATLAB/SIMULINK software
