Analysis, Modelling and Simulation of a Multiphase Interleaved Buck Dc/Dc Converter for PV Applications

The Continuous Advances in Power electronics technologies and regulation systems have provided an opportunity for designing of efficient Converters for charging process of storage elements, especially in photovoltaic (PV) systems, these converters must have a minimum ripples contents, this can be achieved by using advanced multiphase interleaved DC/DC converters. These converters are used to regulate the output voltage and current of the PV - charging system to obtain an efficient charging /discharging process for direct Energy Storage Systems (ESS), also control the power flow and track the maximum power of the PV modules. In this paper, a design and implementation of a multi-phase interleaved Buck DC/DC converter is introduced for obtaining an efficient PV Battery charging system. Also a comparison between the conventional single phase and the proposed multi-phase interleaved topology is recorded.
