PV Cell fed Step-up Resonant Converter for Induction Motor Drive Application

Abstract

In the hybrid micro grid, processes of multiple dc-ac dc or ac-dc-ac conversions are reduced in an individual ac or dc grid. The hybrid grid consists of both ac and dc networks connected together by multi directional converters. In this micro grid network, it is especially difficult to support the critical load without incessant power supply. The generated power can be extracted under varying wind speed, solar irradiation level and can be stored in batteries at low power demands. In this paper, a hybrid AC-DC micro grid with solar energy, energy storage, and a pulse load is proposed. This micro grid can be viewed as a PEV parking garage power system or a ship's power system that utilizes sustainable energy and is influenced by a pulse load. The battery banks inject or absorb energy on the DC bus to regulate the DC side voltage. The frequency and voltage of the AC side are regulated by a bidirectional AC-DC inverter. The power flow control of these devices serves to increase the system's stability and robustness. The system is simulated in MATLAB/SIMULINK.
