Modeling and control of a cascaded boost converter for a battery electric vehicle

This paper presents the design, modeling and implementation of a cascaded boost converter for its application as interface to battery electric vehicle system. The cascade boost converter is compared with the classical boost converter; the performance of the designed converter is validated through simulation in two different modes, with resistive load and with battery charging electric vehicle system. A non linear control strategy is used to control the power devices of a cascade boost converter and a boost converter. Simulations carried out in Matlab/SIMULINK environment and tests on a prototype setup have verified the capability of this topology in performing desired duties.
