An improved buck boost converter using auxiliary resonance for photo voltaic based dynamic voltage restorer

Abstract

Conventional Dynamic Voltage Restorers depend upon the grid for storing necessary energy that is required for sag and swell compensation. The objective of this work is to maximize the energy harvested from the PV cell using suitable DC–DC converter for maximization and stabilization of the energy harvested from the photovoltaic system. The maximization of energy harvested is done by increasing the efficiency of the dc–dc converter by using the concept of soft switching and resonance together. The converter discussed above was simulated using Power Sim software and it was compared with a laboratory setup.
