Definitions

the invention relates to a high-performance switching power supply according to the preamble of claim 1.
Switched-mode power supplies have the essential advantage over conventional power supplies that they have a higher degree of efficiency with a lower weight and a smaller volume at a correspondingly lower cost. This is offset by the disadvantages of a somewhat more complicated switching technology, stronger RF interference and greater difficulties in smoothing the output voltage.
the present invention is based on the object of finding a solution that is as optimal as possible also with regard to the necessary space and material requirements for improving smoothing and RF interference suppression in high-performance circuits.
the arrangement according to the invention corresponds to a choke with two turns, without the winding material having to be wound with its correspondingly large cross section because of the high current strengths. Another advantage is the good suppression properties of the filter circuit due to the symmetrical structure.
the basic circuit diagram of a switched-mode power supply shown in FIG. 1 shows on the input side a line rectifier NGL with subsequent switching stage SST, which generates a square-wave voltage from the direct voltage by chopping and converts it with the aid of a transformer.
the filter circuit consists of a smoothing choke L G switched on along the one output line and of a smoothing capacitor C G located in the shunt arm.
Such a sieve circuit has the disadvantage that the HF interference radiation caused by the switching stage SST and symbolized by lightning arrows is only sufficiently reduced in the choke branch. In the second output line leading to the negative pole, which contains no smoothing choke, the RF interference radiation reaches the output unhindered.
both chokes L G1 , L G2 each consist of one turn and, moreover, both turns are passed through the coil core SPK in the same winding direction. This means that the currents I flowing from point A to the positive pole or from the negative pole to point B add up through the coil core SPK.
FIG. 5 A structure which is particularly advantageous for high-power switching power supplies for the filter chokes according to FIGS. 3 and 4 is shown in FIG. 5. It shows in perspective Representation of a conductor track assigned to the choke L G1 in the form of a copper strip.
This copper strip is subdivided into three partial webs connected at one end, of which the middle partial web is guided as the first turn W1 through the bore of a tubular coil core SPK, while the two outer partial webs are returned on the outside of the core.
These two outer partial tracks are extended beyond the core and, with their extended ends bent at right angles to the core axis, are connected to one of the two output terminals - here with the positive pole.
the beginning of the middle partial web is also bent at right angles to the core axis and preferably in the opposite direction to the two outer partial webs.
the conductor track assigned to the other choke L G2 is likewise a copper strip and, starting from the second output terminal, runs first between the two outer partial tracks of the other choke L G1 and then as a second turn W2 through the coil core SPK.
the bent ends of the two outer sub-paths of inductor L G1 and the intermediate conductor path of inductor L G2 serve expediently as mounting surfaces for one or more smoothing capacitors C G connected in parallel.
