High Voltage Gain Switched Capacitor Boost Converter with ANFIS Controller for Fuel Cell Electric Vehicle Applications

Designing of a high voltage gain or high step-up boost converter is the major challenge in the high power applications. In this work, a high voltage gain Switched Capacitor Boost Converter (SCBC) is designed for fuel cell electric vehicle (FCEV) applications. The designed converter achieves the high voltage gain with low duty cycle and reduces the voltage stress across the power semiconductor switches. The converter output voltage is given to the Brushless DC (BLDC) motor through a DC link and a Voltage Source Inverter (VSI) for the propulsion of the vehicle. An adaptive neuro-fuzzy inference system (ANFIS) based MPPT technique is adopted for the fuel cell system for extracting the maximum power at different temperature conditions. The performance analysis of fuel cell electric vehicle system with SCBC is done by using the MATLAB/Simulink environment.
