An Adaptive Power Electronic Interface for EV

Abstract

This paper describes the usage of a Fuzzy-based bidirectional DC-DC converter-fed induction motor for EV applications. A 3-phase variable speed induction motor (used as a load) is supplied with a battery through AC-DC and DC-DC converters. Varying speeds of the induction motor are achieved using the FOC-SVPWM technique. A Bidirectional Converter DC to DC is used to conserve the power generated through regenerative braking. A fuzzy logic controller is employed to obtain an optimal power flow between the battery and load (Induction motor). Mathematical modeling of SVPWM -FOC, an adaptive fuzzy rule base for all the test scenarios, has been presented. Test scenarios like sudden changes in speed, motoring, and regeneration modes of the vehicles have been considered for simulation. The proposed model has been evaluatedusing a MATLAB/Simulink environment has been used to evaluate the model. Results are analyzed and presented.
