ABSTRACT:
A circuit configuration for a self-oscillating blocking-oscillator switched-mode power supply includes a transformer having a primary winding. A bridge rectifier has an output terminal. A semiconductor switch element is used for clocked application of an alternating voltage rectified by the bridge rectifier and unsmoothed to the primary winding. A control device has input terminals. The control device triggers the semiconductor switch element according to at least one primary current signal to be applied to one of the input terminals of the control device. A one-way rectifier configuration has an input side connected to the output terminal of the bridge rectifier and an output side connected through an RC element to the one input terminal of the control device.
