A variable step size fuzzy logic controller based maximum power point tracking controller for proton exchange membrane fuel cell powered resonant pulse width modulation high step up converter with multicarrier sinusoidal pulse width modulation inverter fed induction motor

Abstract

Summary A variable step size Fuzzy logic based MPPT algorithm is proposed to ensure maximum power extraction from 1.26 kW Proton Exchange Membrane Fuel Cell (PEMFC). The Resonant PWM High Step up Converter (RPHC) is designed with soft switching capability to boost PEMFC output voltage and ensured optimum power tracking during dynamic operating condition by triggering RPHC switches with pulses generated from MPPT controller. The proposed variable step size FLC controller results are compared with conventional P&O and IC algorithm. To run a three‐phase induction motor, three‐phase Voltage source inverter connected at the output port of step up converter whose switching pattern is given by Multicarrier Sinusoidal Pulse Width Modulation (MSPWM) controller which reduces THD in output voltage and current. A detailed simulation analysis is done with MATLAB/Simulink environment and discussed the results. The hardware prototype model is implemented to validate the simulation results.
