Design and Development of Bidirectional Integrated Converter for Plug-in Electric Vehicles

Abstract

This thesis focuses on the evolution, analysis, and design of improved single-stage based integrated converters aimed at on-board applications of plug-in electric vehicles (achieving complete types of vehicle operation, i.e., plug-in charging, propulsion, and regenerative braking using a single-converter) (PEVs). For better gasoline compromising with health is a big concern to deal with these issues of health due to environmental impacts gasoline may be replaced with EV Collectively known as plug-in electric vehicles (PEVs). In the vehicle's engine has an additional battery charging system, usually between the battery and the traction motor inverter. A bidirectional DC-DC converter is used. This converter is charged with increasing battery voltage and efficiently controlling power during cruising, acceleration, and regenerative braking. The bidirectional DC-DC converter is only employed in propulsion or regenerative modes in such classic designs, and the battery is charged by yet another AC/DC converter. This includes different converters for two independent operating modes, regardless of the converter configurations. Merging the additional mount entity with the bidirectional DC-DC converter, which is used during touring and stepping up modes, would be a competent alternative for providing a highly compact, lightweight, and affordable charging scheme. Both AC-DC and bidirectional converters are used in this notion. This study proposes a novel integrated converter-based charging system for EVs. To function efficiently and achieve all of its operating modes, the created system only requires a limited number of power electronics components. In the typical system, the bidirectional DC-DC converter is integrated into the on-board resulting in a single converter for the whole operation of PEVs. When compared to an existing integrated converter, the major improvement of this integrated converter is an completely effective progress in propulsion as boost mode and regenerative as buck mode technique.
