Power converters adapted for providing a plurality of n+1 control parameters for independently supplying a plurality of n lamps and one DC current consumer, usually comprise n inverters, one for each lamp. The power converter ( 10 - 50 ) according to an exemplary embodiment of the present invention provides an independent control of each lamp by using n tunable resonant circuits (L 2 ,L 3 ,C 5 -C 8 ) but only one space-consuming inverter ( 30 ) and one transformer (Tr. 1 ), wherein each tunable resonant circuit comprises a magnetic amplifier (L 2 ,L 3 ). Advantageously, this leads to a reduction in size, which may lead to more compact and cheaper LCD applications.
