    摘要： The present invention relates to a circuit arrangement for operating at least one high-pressure discharge lamp (La) having a voltage transformer (10) having at least one electronic switch (T1; T2); an actuating circuit (12) for actuating the at least one electronic switch (T1; T2) of the voltage transformer (10) at a prescribable transformer frequency (f
    s ); a first and a second connection for coupling to the at least one high-pressure discharge lamp (La); a first capacitor (C1) which is coupled between the voltage transformer (10) and the first connection for the discharge lamp; and a charging apparatus (14), which is coupled to the first capacitor (C1) in order to charge it with a DC voltage to an ignition voltage for igniting the high-pressure discharge lamp (La); wherein the voltage transformer (10) comprises a transformer (Tr), wherein the transformer (Tr) comprises a primary inductance (P1; P1a, P1b) having at least one first and a second connection and a secondary inductance (S1) having a first and a second connection, wherein the first capacitor (C1) is coupled between the first connection of the secondary inductance (S1) and the first connection for the at least one high-pressure discharge lamp (La). The present invention moreover relates to an appropriate method for operating at least one high-pressure discharge lamp.
