The Role of DC/DC Converters in Electric Vehicles

DC/DC converter is an auxiliary electronic device that converts high-voltage DC to low-voltage DC in new energy vehicles, which is divided into two application scenarios: low-power DC/DC converter and high-power DC/DC converter.

Among them, low-power DC/DC converter is used as a high-voltage to low-voltage device and 12V voltage stabilizer, and the role of high-power DC/DC converter is a high-voltage booster, which is an indispensable device in new-energy hybrid electric vehicles and fuel cell vehicles.

The role of the electric car dc dc converter is to convert the high voltage of the power battery pack to a low voltage of 14V or 28V, both to power the entire vehicle's low-voltage electrical equipment and to charge the auxiliary battery.

One of its functions is to provide power to the power steering system, air conditioning, and other auxiliary equipment. Another function is to be connected in series with a supercapacitor in a composite power system to regulate the power output and stabilize the bus voltage.
