SIMULATION OF PV WITH MPPT ALGORITHM FOR LLC RESONANT DC-DC CONVERTER EMPLOYING BURST MODE CONTROL

Abstract

In this paper burst mode control for LLC converter is discussed along with the modeling of PV array and Maximum Power Point Tracking (MPPT) algorithm are presented. LLC can regulate the output voltage even at no load condition through ZVS and ZCS. Hence LLC is used to step up the voltage of PV and MPPT is implemented to track maximum power at variable weather conditions. This paper focuses on Burst mode control compared to the conventional PWM technique to improve the efficiency of the proposed converter under light load conditions. Simulation results are presented to show the significance of the burst mode control scheme and the results are verified..
