    摘要: A pulse booster circuit (10) comprises a first pulse transfer path (41) and a second pulse transfer path (42) extending between input terminals (1 la; l lb) and output terminals (12a; 12b). A series arrangement of a capacitor (20) and a first breakdown switch (13) is connected between said two input terminals (1 la; l l b). A series arrangement of a second breakdown switch (14) and a primary winding (31) of a transformer (30) is connected in parallel to said capacitor (20). A first output winding (32) of said transformer (30) is incorporated in said first pulse transfer path (41), while a second output winding (33) of said transformer (30) is incorporated in said second pulse transfer path (42).

    摘要: An ignition circuit for generating high voltage pulses to a discharge lamp is provided with a switching element (SW1) to enable to stop generating said high voltage pulses when the lamp does not ignite or has ignited. The switching element (SW1) is connected between the input terminals (ground, Vdc) of a supply voltage and a parallel circuit of a capacitor (C1) and a series connection of a breakdown device (B1) and a primary winding (W1) of a transformer (T1). Switching the switching element (SW1) non-conductive prevents that the capacitor (C1) from charging.

    摘要: A gas discharge lamp (2) is operated with an alternating current. A positive lamp current (Ip) is generated with a positive current intisity (Ip) for a positive duration (τp). A negative lamp current (IN) is genrated with a negative current intensity (IN) for a negative duration (τN). A duty cycle (D=τp/(τp+τN)) differs from 50%. A current ratio (R=Ip/IN) differs from 1.

    摘要: The invention relates to a high-pressure discharge lamp (1) provided with a discharge vessel (2) made of quartz glass which encloses a discharge space (3) having an ionizable filling and an electrode (4). The discharge vessel (2) is provided with a seal (5) which preferably encloses an Mo foil and forms a feedthrough for an electric conductor (6) to the electrode (4). At the location of the foil, the seal (5) has a gastight sealed cavity (10). According to the invention the cavity (10) is free of a capacitive coupling. This improves reliable ignition.
