48V-12V DC-DC Converter Solutions for the Automotive Industry

With the development of the automotive industry, the demand for automotive electrical features and functions has been growing, especially since the first electric lighting was adopted in cars in 1898. In order to cope with the limitations of the 12V system, the automotive industry is gradually turning to the 48V system. This shift can not only provide greater power capacity and reduce the size of wires and connectors, but also support more advanced electrical functions and effectively reduce energy consumption. In current mild hybrid electric vehicles (MHEVs), two batteries are usually equipped: a 48V battery and a traditional 12V battery. Among them, the 48V-12V DC-DC converter plays a key role. It connects the two batteries to ensure the efficient operation of the power system.
