In response to the demanding operating environment and safety requirements of automotive electronics, the core components include automotive-grade power conversion chips, DC-DC converters, over-temperature/over-current/over-voltage protection devices, electromagnetic compatibility (EMC) filters, and high-voltage protection devices. On one hand, they ensure stable power supply for the vehicle's 12V/24V power system and the conversion of high-voltage electrical energy in new energy vehicles, guaranteeing the long-term stable operation of various electronic modules. On the other hand, they resist risks such as strong vibrations during vehicle travel, wide temperature range changes, electromagnetic interference, and high-voltage leakage, ensuring the safety of passengers and drivers as well as the reliability of the vehicle's electronic system, in line with the strict vehicle-grade certification standards of the automotive industry.
