Method for function control of uninterruptible power supply unit for computer, involves supplying main voltage parallel to components of unit, and controlling function of unit, without connecting components with load at output side

摘要

#CMT# #/CMT# The method involves supplying main voltage (30) of a load (40) to be operated. The main voltage is supplied parallel to components e.g. control module, filter (21), rectifier (22), accumulator, accumulator interface (23) and inverter (24), of an uninterruptible power supply unit (100). A function of the uninterruptible power supply unit is controlled, without connecting the components with the load at an output side. The load is switched between a direct network operation and a secured inverter operation by a bypass switch (25) of the uninterruptible power supply unit. #CMT# : #/CMT# An independent claim is also included for an uninterruptible power supply unit comprising a diagnostic module. #CMT#USE : #/CMT# Method for function control of an uninterruptible power supply unit to protect an electrical and electronic device i.e. computer, from complete power failure. #CMT#ADVANTAGE : #/CMT# The function of the uninterruptible power supply unit is controlled, without connecting the components with the load at the output side, thus increasing functional safety of the uninterruptible power supply unit. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic diagram of components of an uninterruptible power supply unit. 21 : Filter 22 : Rectifier 23 : Accumulator interface 24 : Inverter 25 : Bypass switch 30 : Main voltage 40 : Load 100 : Uninterruptible power supply unit.
