Energy Management Converter With A Flyback Snubber Fed Drive For Hybrid Electric Vehicle

Abstract

Nowadays energy management converter for electric drives are commonly being used for electric vehicles applications, due to various advantages, such as: nearly zero emission and energy recovery during braking operation. To fulfill these requirements converters with bidirectional power flow capabilities are required to connect the battery to the dc link of the motor drive system. A hybrid electric vehicle is required to function in three different modes namely: acceleration mode, normal (steady-state) mode and braking (regenerative) mode. In the present work open loop and closed loop operation of bi-directional dc-dc full bridge converter with a flyback snubber feeding a dc motor and its energy recovery due to regenerative braking has been demonstrated. The simulations are carried out using Simulink/ MATLAB 7.6.0 (R2009b) package.
