Device for power supply system of piezo element of spacer sensor for motor vehicle, particularly passenger car, has voltage converter that utilize electrical voltage as input voltage provided from power supply system

摘要

#CMT# #/CMT# The device has a voltage converter (2) that utilizes an electrical voltage as an input voltage provided from a power supply system (1) of a motor vehicle. A controller (4) is provided, which is downstream to the voltage converter, with which an output voltage of the voltage converter is introduced a piezo element (6) for power supply system. #CMT#USE : #/CMT# Device for power supply system of a piezo element of a spacer sensor for a motor vehicle, particularly passenger car. #CMT#ADVANTAGE : #/CMT# The device has a voltage converter that utilizes an electrical voltage as an input voltage provided from a power supply system of a motor vehicle, and hence ensures a compact power supply system device, which is economical. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block diagram of a power supply system device. 1 : Power supply system 2 : Voltage converter 4 : Controller 6 : Piezo element 7 : Spacer sensor.
