Taking the example of a door module, existing 14V loads can be operated on the 42V PowerNet and what advantages result for operation of adjusted 42V loads.
The following different problemsolving approaches are presented for typical loads such as power windows, electrically positioned and heated outside mirrors, and central locking:
• Power windows: A test motor specially developed for the 42V supply is continuously operated directly from the electrical system using suitable power
semiconductors.
• Central locking: A conventional 14V motor is operated at 42V, its operating point being set using pulse width modulation (PWM).
• Remaining door module: Smaller 14V mirror motors and the control electronics are supplied from a second 14V system. This second supply can be taken from the current 14V system or generated locally by appropriate switching regulators, or even by a central DC/DC converter from 42V.
