Design and Control of High Voltage Gain Interleaved Boost Converter for Fuel Cell Based Electric Vehicle Applications

Abstract

The need for power is raising rapidly all across the world right now. This last period has seen a dramatic increase in the severity of global warming brought on by the earth's climate. Greenhouse gas emissions from customary fossil fuel-depend vehicles have risen to the forefront of environmental concerns as the number of cars on the road continues to rise. Pollution from traditional internal combustion engines is rising at an alarming rate. A growing number of people see renewable energy based techniques as ideal answers to the problems of rising fuel efficiency regulations and falling pollution levels. In recent years, interest in hydrogen's potential as a new energy vector has grown rapidly; this is because hydrogen can be converted to electric energy in a fuel cell (FC), making it a viable option for powering fuel cell electric vehicles (FCEV). In comparison to other fuel cell types, the working temperature range of a Proton Exchange Membrane Fuel Cell (PEMFC) makes it the best option for usage in automobiles. As the value of FC modules is rather low, a further action is necessary for interfacing with utility grids in FC-based power sources. Even though a traditional boost converter may increase the DC bus voltage from the FC to the necessary level by the inverter, doing so at a very high duty ratio reduces the converter's efficiency and effectiveness. In this study, we propose using high-gain interleaved DC-DC converters to fix this issue. To provide the electric vehicle's power train, this research introduces a radial basis function network (RBFN) with maximum power point tracking (MPPT) method for PEMFC. To determine the PEMFC's optimum operating point, the planned NN-MPPT method employs a RBFN. FCEVS require dc-dc converters with more switching frequencies and heavy voltage gains for propulsion. A three-phase high voltage-gain interleaved boost converter (HV-GIBC) is also developed for the FCEV method to achieve high voltage-gain. Power semiconductors are stressed by leakage current fluctuation and voltage fluctuations are lessened by the interleaving method. We evaluate the MATLAB/Simulink platform's Fuzzy Logic controller against the RBFN-based MPPT controller in an FCEV system's performance evaluation.
