Multi Input and Multi Output Zeta Converter for Hybrid Renewable Energy Storage systems

Abstract

In this paper, multi input multi output (MIMO) Zeta converter is proposed for hybrid renewable energy applications. The Traditional MIMO is modified with Zeta converter for its Continuous output current, high voltage Gain, Buck boost capability & performing higher switching frequencies. Here there are five ports among them three input ports and two output ports. The Inputs are PV, Battery & Super capacitor. The converter is controlled by sliding mode controller (SCM) and it has fast system response and it controls peak overshoot. This converter boosts the PV panel, battery and fuel dc voltage to regulated output dc voltage without any losses. This topology provides a positive output voltage. Modes of operation for multi port zeta converter are explained. To test the effectiveness of the proposed topology, simulation model is developed using MTALB and suitability of the proposed model is tested using experimentation.
