ARRANGEMENT COMPRISING AT LEAST TWO POWER SUPPLY UNITS AND AT LEAST ONE LOAD, COMPUTER SYSTEM AND METHOD TO CONTROL THE ARRANGEMENT

摘要

#CMT# #/CMT# The arrangement has power supply units (1A, 1B) for generating an output-side operating voltage. A current consuming component (8) is electrically coupled with the units, where power consumption of the component is less than combined output power of the units in a normal operating mode. A control unit monitors functions of the units, switches the component from the normal operating mode into a limited operating mode during failure of one of the units and deactivates one of the units when one of the units is not necessary to provide power required for the normal mode. #CMT# : #/CMT# Independent claims are also included for the following: (1) a computer system comprising a power supply unit and current consuming component arrangement (2) a method for controlling a power supply unit and current consuming component arrangement. #CMT#USE : #/CMT# Power supply unit and current consuming component arrangement for use in a computer system (claimed). #CMT#ADVANTAGE : #/CMT# The control unit monitors the functions of the power supply units, switches the component from the normal operating mode into the limited operating mode during failure of one of the units and deactivates one of the units when one of the units is not necessary to provide the power required for the normal operating mode, thus ensuring high reliability of the arrangement, ensuring power supply of the current consuming component even when failure of the power supply unit occurs, and improving energy balance in the arrangement. The power supply unit and current consuming component arrangement is simple and is cost-effectively produced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic circuit diagram of a power supply unit and current consuming component arrangement. 1A, 1B : Power supply units 7 : Power supply line 8 : Current consuming component 9 : Clock generation circuit 10 : Circuit breaker.
