Two-Phase IPOS DC-DC Step-up Converter for PV Interface

Abstract

As solar modules grow increasingly prevalent in power generation, more efficient and effective power conversion technologies are required. Traditional power converters that convert power from several solar modules in series face several challenges, including partial shading and tracking accurate maximum power points. This paper presents a doubler step-up converter suitable for increasing the voltage gain, processing photovoltaic power, and extracting highest possible solar energy from solar modules. The converter consists of two phases of boost converters connected as input parallel and output series, reducing the input current ripples and allowing for electromagnetic interference reduction and better current measurements. The theoretical background of the converter is illustrated and supported with simulation results.
