ABSTRACT:
A dc converter for supplying an electronic device in which a feed voltage is summed with an additional voltage generated by rectification and wherein pulse-width control is provided at the primary side of the converter transformer. According to the invention, the additional voltage is generated by rectification in the same manner as the main output voltage is generated, i.e. the rectifier circuit outputting the additional voltage is similar to that outputting the output voltage.
