Switched-mode power supply, especially for a television set

摘要

A switched-mode power supply, for example for a television set, in the case of which an operating voltage which is produced is additionally stabilised by a voltage stabiliser. According to the invention, the voltage stabiliser consists of a thyristor (15) which is triggered by the pulse voltage of a secondary side, via a regulated network (16-19). As a result of this solution, a heat sink for a stabilisation IC which was previously used is saved. <IMAGE>
