High performance charger design of a dual feed BLDC motordriven electric vehicle

Abstract

This paper presents the designing details of a soft switched fast charging PV charger and a PFC rectifier for Dual Feed BLDC Motor Driven Electric Vehicle. The vehicle is motorized by batteries which are charged through-conventional power source and PV module. In order to-facilitate fast charging and to reduce power loss substantially, a four channel interleaved boost converter has been-integrated with solar module where switching losses are minimized using zero voltage switching (ZVS) technique. In addition to this, a discontinuously switched vienna rectifier has been designed that guarantees reduced THD and improved PF. The speed control of the BLDC motor is done using hall sensor technique. The process of selecting the suitable components for this application is studied and simulated for various conditions where each of the components is practical.
