Abstract
Abstract An uninterruptible power supply system (UPS) includes a coupling choke ( 5 ) being operably arranged between an electrical load ( 2 ) and an external source of power ( 4 ). A generator ( 8 ) is operably connected to the coupling choke ( 5 ) on the side of the electrical load ( 2 ), and it is designed and arranged to be active during normal conditions and during trouble conditions. Trouble conditions are to be understood as conditions when the external source of power ( 4 ) fails. A converter ( 9 ) is operably connected to the coupling choke ( 5 ). A substitute storage device for electrical energy is operably connected to the coupling choke ( 5 ) on the side of the electrical load ( 2 ) by the converter ( 9 ). A fast-opening switch ( 6 ) is operably connected the coupling choke ( 5 ) on the side of the source of power ( 4 ), and it is designed and arranged to open in case of occurring trouble conditions. A first unit ( 12 ) is designed and arranged to sense an output voltage being supplied to the electrical load ( 2 ) and to produce a measuring signal ( 25 ). A second unit ( 27 ) is designed and arranged to control the output voltage, to use the measuring signal ( 25 ) as an input signal, to deliver a control signal ( 26 ) as an output signal to the converter ( 9 ) and to control the output voltage to attain a desired shape over time.
