Abstract: A carrier board which has a plurality of conduction layers is provided. A plurality of electronic units are produced on surface regions of the board with electronic components arranged at regular spacing. The surface regions, for use in a separation operation, are held at predetermined separating regions to a frame. The frame has an externally contactable, connecting region for an operating voltage or load for electronic units. Each electronic unit can be acted upon with the operating voltage or a load, by way of supply, load and/or signal lines in the frame and at separating regions of the carrier board. The electronic units can be operated and tested by the supply as well as the load and/or signal lines in a full-load mode of operation.

Abstract: The invention relates to a power supply module for high output currents, particularly a DC-DC converter, with a plate-shaped carrier element (10) configured to interact with a planar inductor and having a plurality of conductor layers, which has a suitably formed opening (12) to receive a core element of the planar inductor, on the component side is formed for automated mounting of electronic components (16), particularly a power semiconductor (14), and on the output side has a contact arrangement (40) to discharge the high output current. On the component side a strip- and/or rail-shaped bridge element (18) is provided, which forms a conductor for the output current and has a conductor cross section greater than 2 mm2. The bridge element, as a component independent of the carrier element, is preferably mounted and contacted on the carrier element by means of an automated assembly process.

Abstract: The invention concerns a voltage converter of the flyback converter type, having a switching element on the primary side in relation to an inductor and an output capacitor on the secondary side which can be charged as a reaction to a current which flows in the inductor and which is switched by the switching element, said output capacitor being associated with a blocking element on the secondary side, wherein the blocking element is in the form of a further switching element which can be put into a blocking condition by a control signal, and there are provided control means for production on the primary side of the control signal, which are such that the control signal is produced a predetermined time interval before a conducting condition of the switching element on the primary side.
