CESA 2012 abstract
With the innovative 12V start-stop functions, there are two new upcoming challenges to be solved, powernet stabilization and increased activation cycles.
The presentation will show semiconductor solutions for powernet stabilization, like dual battery switches, as well as solutions for replacing mechanical relays. Special interest is here also given to electronic fuse function, weight reduction by improved wire harness and a more flexible power distribution partitioning, as well as a reduction of electric power losses.
Finally the presentation will cover the 48V powernet requirements for semiconductors in Mild-Hybrid systems. Different system architectures will be discussed with their specific application needs and first 48V semiconductor families like MOSFETs, driver ICs, Voltage regulators and transceiver devices will be proposed.
