| titleOfInvention | Circuit arrangement |
| abstract | A circuit arrangement according to the invention comprises a DC/AC converter for operating a discharge lamp (LA), which DC/AC converter is provided with: input terminals (K1, K2) for connection of the DC/AC converter to a DC voltage source; a switching circuit (A) connected to the input terminals and provided with at least one switching element (S), which switching element has a control electrode (Sa) and a main electrode (Sb), which switching element has a control circuit (B) between the main electrode and the control electrode with a series arrangement of means (Tb) for generating a control signal for the switching element and of first decoupling capacitive means (Cd), and which switching element is conductive when a voltage is present between the control electrode and the main electrode with a first polarity and with a value which exceeds a threshold value (Vt); a load branch (E) comprising at least inductive means (Ta) and output terminals (K3, K4) for connection of the discharge lamp, which load branch is supplied via the switching circuit (A), characterized in that the control circuit (B) comprises means (I) for generating a DC voltage component (Vdc) between the control electrode (Sa) and the main electrode (Sb) with a polarity which is opposed to the first polarity. The switching element of the circuit arrangement according to the invention is capable of fast switching also in the case of a short duty cycle. |
