ABSTRACT:
A DC voltage convertor utilizes a switching transistor for switching the primary of a power transformer inserted in the emitter-collector circuit of the transistor, the base of the transistor is connected to the secondary of a control transformer which has its primary connected in series with the primary of the power transformer. A further secondary winding on the control transformer is connected to a transistor control circuit, which is controlled by a voltage dependent on the output voltage of the converter, provides voltage stabilization without galvanic connection between the primary and secondary sides.
