PCB embedded DC/DC 42 V/14 V converter for automotive applications

A DC/DC 42V/14V converter for automotive applications is constructed in an integrated PCB technology. By using integration technologies such as embedded passives into PCB, heat spreading and thermal vias thermal management technologies, the number of construction parts and processes can be reduced thus reducing the cost and size of power electronic converters. Since this technology is limited in power level, a modular arrangement can be employed to achieve desired power levels. Furthermore, the converter is designed in an integral manner, combining electrical, thermal and spatial design in order to satisfy the stringent requirements of the automotive market, in particular those related to the volume and high operating temperature
