Definitions
- the invention relates to a high-performance transformer according to the preamble of patent claim 1.
- Winding conductors for such transformers are known from European patent application EP-A 0133220 and French patent FR-PS 1198126.
- the object of the invention is therefore to improve the efficiency with regard to frequency and current behavior in a high-performance transformer.
- a high power transformer e.g. in clocked power supplies is mostly controlled with rectangular primary signals and harmonic currents up to at least a factor of 10 above the clock frequency are necessary for the approximately correct transmission of the square-wave signal.
- This measure also reduces the eddy current losses in the transformer to a minimum, since the differences in current densities within a single conductor are relatively small.
- each individual conductor occupies every layer in the overall cross-section of the strand just as often and for as long as any other individual conductor.
- the parallel strands of the secondary winding enable exact current balancing, which is necessary for a distribution of the current, e.g. on a number of diodes connected in parallel is a requirement.
- FIG. 1 schematically shows a high-performance transformer U, the secondary winding SW of which consists of a turn with six strands ST1 to ST6 connected in parallel. At one end of the secondary winding SW, all strands ST1 to ST6 are connected to a collection point SA. At the other end of the secondary winding SW, each phase is connected to a rectifier diode GD1 to GD6.
- the six freewheeling diodes FD1 to FD6 connected in parallel connect the collection point SA to the outputs of the rectifier diodes GD1 to GD6.
- the high-frequency currents in the secondary circuit between the freewheeling diodes FD1 to FD6 and the rectifier diodes GD1 to GD6 cause, due to the design of the secondary winding SW according to the invention, only extremely low losses, which result in a low temperature (for example below 80 ° C.) of the high-power transformer U and one bring high efficiency (e.g. over 96% at 600 amps).
- the primary winding PW and the secondary winding SW consisting of a single turn lie between the base and cover parts BD consisting of ferrite material, each with E-shaped profiles.
- the internal primary winding PW is composed of a number of turns wound around the central web M of the respective E-shaped base and cover parts BD with the strand according to the invention.
- the single turn of the secondary winding SW hugs the structure of the primary winding PW in a U-shape. This ensures the best possible coupling even with a very high gear ratio.
- the secondary winding SW consists of six strands ST1 to ST6 lying parallel to one another in one plane, which in turn are each formed from four strands L1 to L4 lying parallel to one another.
- the strands L1 to L4 in turn are designed as a woven copper tape B with a rectangular cross section and contain a large number of electrically insulated individual conductors E which are twisted or intertwined with one another.
- the cross section of the individual strands ST1 to ST6 is thus also rectangular, which results in a band-shaped secondary winding SW.
- the six strands ST1 to ST6 are arranged in steps with increasing length in order to keep the connecting lines to rectifier diodes D1 to D6 in a row as short as possible.
- a flange F for connection to the collection point SA provided that electrically and mechanically connects the six strands ST1 to ST6 and thus also all individual conductors E of all strands L to one another.
- the individual conductors E of the respective strings ST1 to ST6 are electrically and mechanically connected to one another with the aid of a cable lug KS1 to KS6.
- shrink tubes (not shown here) can be used, which are each pulled over one strand.
- the configuration of the primary winding as a strand with individual conductors E insulated from one another makes it possible to use a single conductor of the strand as the demagnetization winding of the high-power transformer. This has the advantage of a good coupling and circuit simplifications. However, it would be advisable to provide a single conductor of the strand with a surface color that makes it distinguishable from the other individual conductors.
