Recently, the area of Hybrid Electric Vehicles (HEV) has seen a tremendous growth all over the world. Due to increasing levels of emissions from the conventional vehicles, rising fuel prices and environmental concerns due to global warming, entire focus of automotive industry is shifted to development of HEV’s. The HEV’s are classified into various configurations depending upon the degree of hybridization which include the performance of the IC engine and electric battery simultaneously for the traction purpose. The physical overview and modeling of Hybrid electric vehicle is discussed. The importance of the dc-dc converter which acts as an interface between battery and the motor drive for bi-directional power flow is proposed .In this paper, bi-directional full bridge dc-dc converter and its implementation in Series-Parallel HEV is presented .This converter topology accounts for motoring as well as regenerative braking operations.

It is necessary for Parallel Hybrid Electric Vehicle (PHEV) to distribute energy between engine and motor and to control state-switch during work. Aimed at keeping the total torque unchanging under state-switch, the dynamic torque control algorithm is put forward, which can be expressed as motor torque compensation for engine after torque pre-distribution, engine speed regulation and dynamic engine torque estimation. Taking Matlab as the platform, the vehicle control simulation model is built, based on which the fundamental control algorithm is verified by simulation testing. The results demonstrate that the dynamic control algorithm can effectively dampen torque fluctuations and ensures power transfer smoothly under various state-switches.
