Abstract (en)
[origin: EP1395096A2] The method involves using a voltage adapter, a controller and at least one load circuit connected to the adapter's inverter forming a resonant circuit in which at least one lamp is operated with a HF current from the inverter whose frequency is varied to set the power taken by the lamp by a first control loop. A second control loop with a shorter cycle than the first stabilizes the power take-up of the at least one lamp to a defined value. The method involves using a voltage adapter, a controller (ST) and at least one load circuit connected to the adapter's inverter forming a resonant circuit in which at least one lamp (LP) is operated with a high frequency current from the inverter whose frequency is varied to set the power taken by the lamp by a first control loop. A second control loop with a shorter cycle than the first stabilizes the power take-up of the at least one lamp to a defined value. AN Independent claim is also included for the following: (a) a voltage adapter for operating fluorescent lamps
