| Abstract: | The design of automotive power supply system will face greater pressure due to the increase of electrical equipment. In the future, it is an inevitable tendency to adopt 42V higher-voltage power supply. As a new type of intelligent power components, DC-DC will meet the requirement of a larger power load. Besides, when matched with existing supply voltages that current vehicles use, it can realize intelligent management of automotive power supply system. As a result, it will promote efficiency and reduce manufacture and maintenance cost. |
