| 摘要 |
The invention relates to a circuit arrangement for operating at least one low-pressure discharge lamp (LP1, LP2) on an inverter (Q1, Q2). The circuit arrangement has a simplified harmonic filter for limiting the harmonic content of the mains current. In the preferred exemplary embodiment, the harmonic filter is formed by the back-up capacitor (C2), the diode (D1), the trapezoidal capacitor (C7) and the resonance capacitor (C6). |
