CIRCUIT ARRANGEMENT

摘要

The invention relates to a circuit arrangement for igniting a high-pressure discharge lamp (L), provided with: input terminals (C, D) for connection to a supply source; a pulse generating circuit (IV) having a natural frequency and provided with a voltage-dependent breakdown element (3); a pulse transformer (1); and an electrical connection between a secondary winding (11, 12) of the pulse transformer and lamp connection points (E, F). According to the invention, the secondary winding is partly shunted by capacitive means (41, 42). This promotes current take-over after lamp breakdown.
