<p>PCT No. PCT/DE96/01153 Sec. 371 Date May 29, 1998 Sec. 102(e) Date May 29, 1998 PCT Filed Jun. 28, 1996 PCT Pub. No. WO97/12500 PCT Pub. Date Apr. 3, 1997A clocked power supply circuit having an at least intermittently active load that is independent of a consumer, in particular for supplying power to gas-discharge lamps as consumers, contains a dc/dc converter comprising a transformer. Switching elements connect the converter to a dc voltage source in the timing of a control arrangement which makes available switching signals for the switching elements as a function of the prevailing output-side load state. The transformer of the dc/dc converter is designed so that two voltages (U+, U-) of differing polarity and magnitude, are able to be tapped off from the output side. At least one of these voltages is regulated and provided for supplying power during operation of the consumer. The at least intermittently active load can be switched to the regulated voltage.</p> |
