Abstract: A circuit arrangement consists of one or several high voltage transformers and rectifier systems usable advantageously for the step-up transformation of medium frequency voltages, for rectification, and smoothing. With the use of the circuit arrangement according to this invention, systems can be built up having small dimensions and low weight, and usable as high voltage supply units providing low standing wave ratio and good dynamic properties. The secondary winding of the high voltage transformer exhibits a flat arrangement. Electrically connected winding systems are designed from the secondary flat windings (flat windings of a predetermined number are connected in series). The resultant AC voltage of the individual, electrically coupled winding systems is connected to the component rectifiers. The component rectifiers are series-connected on the DC side.
