摘要
An apparatus for supplying a DC voltage to a load which can be connected to output terminals. The apparatus has a semiconductor switching element for a clocked application of a supply voltage to a primary of a transformer on the basis of a sequence of driving pulses applied to a control input of the semiconductor switching element. A driving circuit is provided for producing driving pulses. The driving circuit has a first input terminal for receiving an analog load-dependent control signal which is produced by a measuring configuration and governs a duration of the individual driving pulses. The driving circuit also has a second input terminal for receiving a starting signal defining turn-on instants of the driving pulses. The apparatus further has a pulse generator with an output terminal, connected to the input terminal of the driving circuit, for providing the pulsed starting signal on the basis of a control signal. The control signal is also supplied to a first input terminal of the pulse generator, in which pulse generator, the temporal spacing of the individual pulses of the starting signal can be influenced by the control signal.
