Circuit arrangement having LC parallel tuned drive circuitry |
摘要 |
The invention relates to a circuit arrangement for operating a lamp (EL), in particular a low-pressure discharge lamp, with a load circuit which has at least one inductor (L2) and at least one capacitor (C7, C8, C9), and with an invertor which may be configured as a half-bridge arrangement with two switching elements (T1, T2), and with a drive circuit (AS) for driving the switching elements (T1, T2). The invention provides that the drive circuit (AS) has at least one LC parallel tuned circuit (L3C3, L4C4). The circuit arrangement according to the invention can be produced without separate cost-intensive wound parts.
