A MULTIPHASE INTERLEAVED BOOST CONVERTER WITH HIGH VOLTAGE GAIN FOR EV APPLICATIONS

For use in electric vehicle (EV) applications, the article suggests a soft switching interleaved boost converter (SS-IBC) with an auxiliary resonant circuit. A multiphase interleaved boost converter, which functions similarly to a single-phase boost converter, can be made by connecting the converter in multiple phases. The converter offers an affordable solution for grid-integrated battery charging applications. Each phase is controlled by a PWM control technique with equal switching frequency and duty cycle. The suggested converter can use a variety of energy systems, including renewable ones like photovoltaic (PV), wind, or fuel cell systems, to supply consistent electrical power to the demand. The study offers a suitable design example and analyses of design circuit parameters and component sizes. The analysis, design, and simulation of the converter provided in this research were verified using the MATLAB simulation tool. An extensive output power converter range from rated power to a minimum power of 460 W with complete soft switching operation on an 8.2 kW setup system with a conversion rate of more than 97%.
