Abstract: A magnetic circuit with several magnetic components integrated on one or more common magnet cores is utilized in a current supply circuit known per se. The circuit comprises a transformer, the secondary winding ends of which are connected to uniform electrodes of a pair of rectifier diodes, the second electrodes of which are connected to one output terminal of the power supply circuit. Additionally, it includes two reactive components, and the first electrodes of the diodes are connected to the second output terminal of the power supply circuit via one of the reactive components. The number of turns of the two reactive components is essentially chosen to equal the number of secondary turns on the transformer. The two reactive components are positioned on each separate core part so that the resulting magnetic flux in common core parts substantially equals the difference between the magnetic flux of the two core parts, and the secondary winding of the transformer is positioned on the common core parts.

The primary circuit and the at least one secondary circuit are tuned individually so that each comprises an oscillatory circuit with coinciding resonance frequencies.

Abstract: A power supply circuit comprising a transformer and rectifier diodes, where the ends of the secondary winding are connected to uniform first electrodes of a pair of rectifier diodes (D1, D2) whose second electrodes are connected to one output terminal (-) of the power supply circuit. According to the invention, also reactive components are provided, said reactive components being connected between the other output terminal (+) of the power supply circuit and the first electrode of respective ones of the rectifier diodes. When one reactance (e.g. L2) can send current (I.sub.L2) through one (D2) rectifier diode serving as an idler diode, while the secondary winding of the transformer draws current (I.sub.L1) through the same rectifier diode, a better utilization of the transformer is obtained than in the prior art, in particular when the output voltage is relatively low, while the output current is relatively high.

Abstract: In a square wave generator for the supply of power to a plurality of electric units the advantages of current controlled and voltage controlled generators may be combined by the provision of two output transformers (T1 and T2) whose primary windings are connected in parallel through diodes (D5 and D6), which in case of overloading are blocked by the voltage of a capacitor which itself is connected through a diode which is also blocked by said voltage.

Abstract: In a transformer of the type having spirally wound copper foil windings, capacitive signal transfer between the primary and secondary windings is avoided by placing the turns of the winding having the smaller number of turns in pairs and placing adjacent each of said turns the turn of the other winding having the same number as the said turn in the sequence of current passage.

Abstract: Apparatus for detecting radar echo signals with a high degree of certainty in the presence of noise. A predetermined number of consecutive, constantly changing invervals are produced having a length equal to the radar pulse width. The resolution of the system is a function of the number of signal positions chosen for examination within each interval. A secondary signal is produced for each signal position and these secondary signals are summed over preselected resolution intervals. A weighting arrangement is provided which weights the individual secondary signals inversely with their distance from the central resolution interval of the set.

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.
