There is disclosed a control apparatus ( 12 ) for a power supply system ( 2 ) operable at a fluctuating line voltage, the system further comprising an energy storage device ( 10 ), and the control apparatus further comprising a line voltage monitor ( 14 ) and an energy storage device controller ( 12 ), wherein the control apparatus is configured whereby the energy storage device is at least partly discharged if the line voltage falls below a first predetermined voltage and the energy storage device is at least partly charged if the line voltage exceeds a second predetermined voltage and in which the first predetermined voltage is substantially lower than the second predetermined voltage. A power supply system ( 12 ) incorporating such a control apparatus is disclosed, as is a method of control thereof. |
