Design of coordinated control scheme for hybrid resonant boost converter and multi level inverter

Abstract

Background/Objectives: This paper focus on Coordinated Control Scheme (CCS) for solar photovoltaic system using Hybrid Resonant Boost (HRB) converter and multilevel inverter. Methods/Statistical Analysis: The Maximum power point tracking has been implemented using Modified Perturb and Observe (MPO) algorithm. MPO algorithm mitigates the output power oscillation and maintain the Photovoltaic panel at maximum operating point. Findings: The HRB converter feeds a DC power to Modified nine level inverter to maintain the quality sinusoidal output. It also reduces the level of harmonics in the output to maintain the system output within standard level. Zero Current Switching (ZCS), Zero Voltage Switching (ZVS) and HRB topologies has been simulated using MATLAB/SIMULINK. The simulation results are used to validate the function of CCS. Applications: The proposed system is implemented for offgrid solar photovoltaic (PV) power plant model.
