HV conversion to SELV- Supply to dynamic, motor driven loads
In order to utilize the energy stored in the HV battery for SELV loads it is necessary to convert HV to a 48V bus, providing a reinforced isolation barrier, in a simple converter that is size and weight-efficient. It also should have a high operating efficiency and fast bidirectional power conversion for regenerative loads. Traditional […]
eFuse: method of implementation and considerations for a robust 12V&24V Smart Power Distribution architecture.
Several automotive trends drive the evolution of E/E topologies towards zonal architectures.

This presentation will show how eFuses offer innovative solutions for further development of […]
Fault tolerant control of Smart Switches in E/E architectures using 10BASE-T1S
Automotive Power Distribution Units and Zonal Controllers use Smart Switches instead of classical fuses to distribute the power to ECUs and sensors. Classical fuses do not support fault tolerant operation – once the fuse has blown, the ECU or sensor will stop operation until the fuse is replaced during car servicing. On the other hand, […]
