Escalating fuel prices and a keen attention to improve air quality have resulted in proliferation of pure electric and hybrid electric vehicles. Fuel savings and reduced carbon footprint are the main enablers for the choice of electric automobiles compared to the conventional vehicles with internal combustion engines. Availability of electric power sources such as lightweight battery packs also has promoted electric drive as a viable option. Both plug-in electric and hybrid vehicles necessitate new power train schemes ensuring safe and reliable operation. The DC-DC converters are the heart of an electric vehicle. They are used to convert the battery voltage to another level as required by the motor drive. Traditionally, most of the automakers use buck boost converter as it enables the bidirectional operation. This paper presents a comprehensive analysis of a dual way DC-DC converter namely split pi converter for an electric vehicle drive train system driving an inverter fed induction motor. The dual way converter investigated has numerous advantages such as inherent bidirectional capability, EMI reduction and reduction of the passive elements. Simulation results and experimental investigations based on a laboratory prototype are presented.
