Definitions

  • aperiodic generator The technique of induction heating generators called aperiodic generator has given rise to the creation of means of precise adaptation of these generators to their load.
  • these means are constituted by adaptation transformers distinct from the aperiodic transformer and which include windings provided with sockets, making it possible to transfer the power of the generator to the particular load connected to its terminals.
  • the present invention relates to a modification of the aperiodic transformer consisting in providing one or more auxiliary windings on the magnetic circuit of the transformer in order to allow this adaptation.
  • the aperiodic transformer is usually made on a magnetic circuit called battleship.
  • the windings are arranged on the central leg on which the winding is carried out.
  • the magnetic circuit loops back on either side of the central leg via 2 side legs.
  • Each of the side legs has a section which is half that of the central leg.
  • These magnetic circuits are usually produced by the juxtaposition of ferrite circuits U.
  • the magnetic flux which circulates in the central leg is divided into 2 equal fractions and which circulates in the lateral legs.
  • the tension by turns induced in a winding wound on each of the lateral legs will therefore have a tension half lower than a winding wound on the central leg. This results in the possibility of producing voltages which will be a fraction of those available between two consecutive turns of the aperiodic transformer.
  • the voltage per turn is of the order of 200 volts.
  • the secondary voltage usually used is 350 to 500 volts.
  • the user will have 0 - 200 - 400 - 600 volt sockets.
  • the voltage generated will be 100 volts per turn instead of 200.
  • this device makes it possible to solve the majority of adaptation problems. It is also possible to install windings on half of each side leg. We will thus have a new division by 2, or 50 volts per turn.
  • This device has two advantages compared to previous techniques, on the one hand, it allows a fine adaptation of the generator from the aperiodic transformer, on the other hand, it avoids an auxiliary adaptation transformer. All the secondary terminals, from 100 to 100 volts or from 50 to 50 volts, are available to the user without having to perform any switching operations.
  • the attached figure illustrates a possible embodiment of the device which is the subject of the invention.
  • the two windings a and b are wound on the central leg of a magnetic circuit e.
  • Two additional windings respectively c and d are wound on the lateral legs of said circuit and connected between the sockets 2 and 3 and 3 and 4 of the secondary winding b. These two windings are themselves provided with a median grip marked 2.5 and 3.5.
