As the mechanical pump of the existing internal combustion engine vehicle would affect the operation of the engine, the energy efficiency was low and the loss to hydraulic pressure was high. However, since the electric pump can control the inverter through MCU, It can be operated independently providing high energy efficiency through precise control and decision when to operate. Recently, electronic pumps are becoming essential in electric vehicles, where efficiency is important by reducing energy consumption and gas emissions. Consequently, the selection of power semiconductors is also becoming more important In order to ensure precise power control and conversion efficiency.
