Power electronic interface and motor control for a fuel cell electric vehicle

In this paper, the power electronics requirements and the controls of an induction motor for fuel cell electric vehicle system are reported. The power topology is selected based on performance, cost, size, volume, manufacturability, component count and simplicity. Another highlight of the topology is the reduction of battery bank (back-up supply) and its control strategy. The proposed approach consists of a full-bridge DC/DC converter to boost the fuel cell voltage. The induction motor operated with vector control is driven by a three-phase PWM inverter supplied by the DC-link voltage. The investigation of the electric vehicle performance due to parameter variation of the induction motor has been presented.
