PCT No. PCT/DE98/01328 Sec. 371 Date Feb. 17, 1999 Sec. 102(e) Date Feb. 17, 1999 PCT Filed May 13, 1998 PCT Pub. No. WO98/58526 PCT Pub. Date Dec. 23, 1998A pump supporting inductor (L1) is added to a half-bridge oscillator circuit for a low-pressure discharge lamp (E) having a capacitive pump path, which inductor improves the pumping action of the pump path and its frequency response. Furthermore, an additional capacitor (C1) is connected between the pump path and the power supply path connected thereto, which capacitor acts as a trapezoidal capacitor in conjunction with the pump path and further improves the frequency response of the pump path. |
