Abstract

Ein Vorschaltgerät für Leuchtstofflampen nutzt zur Takterzeugung und Ansteuerung des Wechselrichters (10) eine aus wenigen Gattern bestehende Logikschaltung in Verbindung mit einer integrierten Treiberschaltung (25). Zur Einstellung eines ausreichenden Sicherheitsabstands zwischen den einzelnen Einschaltimpulsen der Transistoren (11, 12) des Wechselrichters (10) werden zwischen der aus Standardgattern aufgebauten Takterzeugungsschaltung (31) und der Treiberschaltung (25) Tiefpässe eingesetzt.

Figure imgaf001
A ballast for fluorescent lamps uses for clock generation and control of the inverter (10) consisting of a few gates logic circuit in conjunction with an integrated driver circuit (25). In order to establish a sufficient safety distance between the individual switch-on pulses of the transistors (11, 12) of the inverter (10), low-pass filters are inserted between the clock generating circuit (31) constructed from standard gates and the driver circuit (25).
