#CMT# #/CMT# The arrangement (10) has board power supplies (12, 14) providing electric voltages, where one of the electric voltages is higher than another electric voltage. A limiting unit (26) is connected with load branches, which are coupled to one of the power supplies for limiting the value of the former electric voltage. The load branches comprises a voltage tap that is connected with another power supply, where the electric voltage of the latter power supply is provided with latter electrical voltage value for supplying the former power supply by a voltage drop. #CMT#USE : #/CMT# Board power supply arrangement for a motor car. #CMT#ADVANTAGE : #/CMT# The load branches comprises the voltage tap connected with the power supply, where the electric voltage of the power supply is provided with the electrical voltage value for supplying another power supply, thus realizing the arrangement in a simple and effective manner. The limiting unit is connected with the load branches, which are coupled to one of the power supplies for limiting the value of the electric voltage, so that no additional power supply is required for the board power supply, thus reducing the cost and space of the arrangement. The limiting unit and the voltage converter are arranged in a common housing, thus installing the arrangement in a space-saving manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a circuit block diagram of a board power supply arrangement. 10 : Board power supply arrangement 12, 14 : Power supplies 26 : Limiting unit 28 : Communication line 32 : Supply line. |
