ABSTRACT:
In a protective power supply, several isolated D.C. voltages are generated by separate inductive transformers, the primary windings of which are arranged in parallel in the diagonal branch of a bridge circuit which has electronic switches controlled in push-pull manner and arranged in two bridge arms. The transformer windings for the protective power supply provided for transistor pulse converters have a low coupling capacity and a small resistance.
