The charging module is the core component of the charging pile, which relies on power semiconductor devices to achieve core functions such as rectification, voltage regulation, switching, and frequency conversion. With the pursuit of miniaturization and efficiency in charging systems by users, power devices, as the core components of charging piles, are also facing continuous optimization and upgrading. At present, domestic charging stations mainly use silicon-based mosfets and IGBTs as power devices. Below, we will introduce a solution for the charging pile industry application from Fosun.

1、 Application solutions for the charging pile industry

Charging stations are similar to gas stations, and can be fixed on the ground or walls. They are widely used in public buildings (such as shopping malls, public parking lots) and residential parking lots or charging stations, providing charging services of different voltage levels for various types of electric vehicles.
