A DC-DC CONVERTER FOR HYBRID ELECTRICAL VEHICLE

Abstract

Now a days battery fed electrical vehicle are commonly being used because of their advantages over conventional IC engine vehicles. This work aims at comparison of various methodologies for hybrid electrical vehicle. In most application a bidirectional dc-dc converter fed permanent magnet dc (PMDC) motor traction drive system for battery fed electrical vehicle (BFEVs) is being used. There is increase in efficiency with the use of the half bridge non-isolated bidirectional dc-dc converter by maintaining battery voltage level to the motor rated voltage and also a controller which works in both the modes i.e. motoring and regeneration has been suggested for the speed control.
