Abstract
Disclosed is an uninterruptable power supply comprising a switchable input power converter having an input operable to receive a supply power network voltage, the power network voltage being subject to fluctuations which may give rise to a disturbance to any load connected to the power network; and a voltage regulation circuit for controlling the switchable input power converter, thereby regulating its output. The voltage regulation circuit senses the power network voltage; and causes the uninterruptable power supply to generate from the sensed power network voltage a compensatory reactive current indicative of the voltage fluctuations on the power network voltage. The compensatory reactive current is used to compensate for the voltage fluctuations on the power network voltage.

25. A method of regulating a supply power network voltage input of an uninterruptable power supply comprising the steps of:
-
supplying a power network voltage to said uninterruptable power supply, the power network voltage being subject to fluctuations which may give rise to a disturbance to any load connected to the power network; sensing said power network voltage; and controlling said uninterruptable power supply so that it generates from said sensed power network voltage a compensatory reactive current indicative of the voltage fluctuations on the power network voltage, the compensatory reactive current being used to compensate for said voltage fluctuations on the power network voltage. - View Dependent Claims (26, 27, 28, 29, 30, 31)
