The Innovative Configurations of Power Electronics Converters in Electric Vehicle Technology

Abstract

Due to improved efficiency and lower greenhouse gas emissions, electric motors, also known as traction motors, are gradually replacing internal combustion engines (ICEs). Batteries and ultra-capacitors provide all or some of the electrical energy needed for the electric vehicle (EV) to run. In a plug-in or hybrid electric automobile, the internal combustion engine provides the charging energy for the battery or ultra-capacitor. At the same time, the AC supply connected to the grid line does the same. Regenerative braking is how the electric motor charges the battery. The plug-in electric automobile returns the energy from the battery or ultra-capacitor to the AC grid. The conversion process between an electric motor and the grid, and vice versa, requires power electronic converters (PECs). This study clarifies the purpose of PECs in EVs. EV power conversion relies heavily on the bidirectional DC-DC converter. Present are comprehensive analysis, comparison, and implementation of contemporary bidirectional DC-DC converter topologies. The analysis is done on improving PECs to increase the vehicle system's dependability and efficiency.
