Nov. 16, 1965 A. J. HAUCK 3,218,544
REGULATOR Filed Jan. 11., 1963 1 1 FfH F g l INVENTOR flLoysu/s J fi m/0A ATTORNE 5 United States Patent 3,218,544 REGULATOR Aloysius J. Hauck, Milwaukee, Wis., assignor to Basic Products Corporation, Milwaukee, Wis., a corporation of Wisconsin Filed Han. 11, 1963, Ser. No. 250,714 1 Claim. (Cl. 32389) This invention relates to power modulating means and especially to an integrated current regulator including saturable reactors.
In the prior art, when two saturable reactors have been used with DC. control windings, it has been found desirable or necessary to use a series choke in the control winding circuit. Such has required the use of cores and windings for each of the saturable reactors and also a core and windings for the separate choke.
One of the objects of the invention is to provide an integrated saturable reactor and choke combination so as to conserve material and so as to provide a compact assembly.
In one aspect of the invention, an integrated structure is arranged having two spaced saturable reactor cores, each having a saturable reactor gate winding. A single control winding is provided which links the two saturable reactors. A magnetic choke or third core is linked with said control winding so that it will introduce inductance into the control winding means to absorb magnetically the second harmonic voltages induced into the control winding by the saturable reactor cores. In one form, the choke core can be located between the saturable reactor cores. In a still further form, the choke core can have a winding thereon connected to a capacitor to assist in tuning the system.
The integral construction of the two reactors and the choke eliminates connections between separate units and the need for terminals on all of the units. Furthermore, polarity is inherently taken care of in the construction. The elongated structure which is made possible hereby also is convenient for placing in an oil filled tank requiring a minimum of floor space.
Another advantage of the arrangement is that the high harmonic voltages normally appearing across the terminals of the saturable reactor control windings and across the choke will be neutralized in the magnetic circuits. Thus, the net voltage appearing at the terminals will be relatively small as compared with induced voltages appearing in conventional multi-unit construction.
These and other objects, advantages and features of the invention will become apparent from the following description and drawings.
In the drawings:
FIG. 1 is a schematic diagram of one connection for the invention; and
FIG. 2 is a perspective view of one construction.
Referring to FIG. 2, saturable reactor has core 11 with gate winding 12 wound thereon. Saturable reactor 13 includes core 14 and gate winding 15 Wound thereon.
Control winding 16 is wound so as to surround gate windings 12 and 15 and to pass within cores 11 and 14. The choke core 17 may comprise a core having an air gap 18 and in the form shown does not have a separate winding thereon. The control winding 16 has a portion within or associated with said choke core so as to provide an integral choke section in the control winding. The control winding links the saturable reactor cores and the choke core.
The choke core will magnetically absorb the second harmonic voltages induced in the control winding by the two saturable reactor cores. Such will force the saturable reactors to operate in the same manner as though there were an external control circuit choke and yet to so do without an additional separate choke winding. Further, the arrangement will eliminate appearance of relatively high induced voltages across each of the saturable reactor control windings as well as across the choke.
FIG. 1 schematically shows the arrangement of FIG. 2, the parts being given similar reference numerals.
In a further modification, not shown in FIG. 2 but illustrated schematically in FIG. 1, winding 20 may be placed on core 17. Capacitor 21 may be connected to winding 20, such arrangement assisting in tuning the systerm.
The structure is shown as a single phase, two saturable reactor system but it should be apparent that the principles can be applied to a polyphase arrangement and that other configurations can be used without departing from the spirit of the invention except as defined in the appended claim.
What is claimed is:
In an integrated power modulator, the combination including two spaced saturable reactor magnetic cores, saturable reactor gate winding means on each core, choke magnetic core means, tuning winding means mounted on said choke core means, and a single common saturable reactor control winding passing through and linking said two saturable reactor cores and said choke core means so as to introduce inductance into said control winding means to magnetically absorb second harmonic voltages induced into the control winding by said two saturable reactor cores, said saturable reactor magnetic cores and choke magnetic core means being mounted on said single control winding.
