摘要： A pre-conditioner circuit comprising first and second pre-conditioner modules (10, 12), each having an input (Vin1, Vin2) and an output (Vout1, Vout2), the outputs (Vout1, Vout2) being coupled to respective load modules (14, 16). The output (Vout1, Vout2) of each pre-conditioner module (10, 12) is serially connected to the input (Vin2, Vin1) of the other pre-conditioner module (12, 10), such that an arbitrary series of parallel connection of the load modules (14, 16) can be achieved, depending on the rout voltage (Vin). Thus, low voltage components can be used in pre-conditioner modules (10, 12) and the load modules (14, 16), without the need for over-dimensioning.

摘要： The invention relates to a method for driving a gas discharge lamp and relates to a lamp driver circuit for driving a gas discharge lamp in accordance with said method. The method comprises supplying a current to the gas discharge lamp, reversing the direction of the current supplied to the gas discharge lamp and, substantially simultaneously, generating a relatively high voltage. The generated high voltage serves to prevent a series of re-ignitions of the gas discharge lamp that may lead to visible flickering of the gas discharge lamp or to extinction of the gas discharge lamp.
