| description | PCT No. PCT/DE94/01446 Sec. 371 Date Aug. 10, 1995 Sec. 102(e) Date Aug. 10, 1995 PCT Filed Dec. 3, 1994 PCT Pub. No. WO95/17032 PCT Pub. Date Jun. 22, 1995A clocked power supply is proposed which contains a fault current detection means (32) which evaluates a voltage drop occurring at an ohmic measuring resistor (25), and emits a switch-off signal (40) to a clocked voltage converter (5). The ohmic measuring resistor (25) is arranged in a line (24) of the clocked voltage converter (5) in which the alternating operating current of the clocked voltage converter (5) flows, the frequency of which alternating operating current is equal to the frequency of a switching signal (23) with which a circuit breaker (16) is operated. In order to suppress the portion of the voltage drop which can be tapped at the ohmic measuring resistor (25) and whose frequency corresponds to that of the switching signal (23), means, for example a low pass filter (33) and/or a parallel capacitor (26) which bridges the ohmic measuring resistor (25) are provided. The clocked power supply according to the invention is particularly suitable for operating gas discharge lamps (7) which are installed for example in motor vehicles, an effective protection of persons (30) against inadvertent contact with live components being provided. |
