OBC and EV-Charging
Power semiconductors are essential in the operation of OBC and EV chargers, particularly for electric and hybrid vehicles. These components enable efficient power conversion and management, ensuring that energy is delivered to the vehicle's battery quickly and safely. By regulating the flow of electricity between the grid and the vehicle, power semiconductors reduce energy losses, optimize charging speeds, and enhance the overall reliability of charging systems. Additionally, they help to protect the battery from voltage fluctuations and overheating, contributing to longer battery life and a safer charging experience. As electric vehicle adoption grows, power semiconductors will continue to be a key enabler in advancing faster, more efficient, and smarter charging technologies.
