The onboard charger is a crucial component for electric vehicles (EVs), converting AC power from the grid into stable DC power through a rectifier circuit. This DC power is then regulated by a DC-DC converter to charge the EV's power battery.

Internal Structure:

Typically, onboard chargers include:

• EMI Filter Module
• Power Correction Module
• Inverter Module
• Inductive Coupling Module

To meet the increasing temperature and lifespan demands from automotive manufacturers, our new series of capacitors can operate at a maximum temperature of 125°C, with THB capabilities meeting rated voltage, 85% RTH, and 85°C to ensure the stability of the OBC system.
