Abstract (en)
[origin: WO2008119376A1] A circuit configuration for controlling at least one fluorescent lamp is disclosed, wherein the circuit configuration comprises the following characteristics: (i) a half-bridge inverter having at least one downstream load circuit, (ii) at least one coupled capacitor connected to the load circuit and to the half-bridge inverter, (iii) a control device for the half-bridge inverter, the load circuit having connections for at least one fluorescent lamp, (iv) a detector circuit comparing a first voltage to a reference voltage and generating an output signal for actuating the half-bridge inverter based on at least two comparators, wherein the first voltage corresponds to a voltage drop at the at least one coupled capacitor or to a voltage drop modified by a voltage divider at the at least one coupled capacitor.
