Abstract
A transformer for voltage regulators has a first core provided with four legs and two common base plates, which are magnetically joined to the four legs, with an input winding being wound on the first and second legs, an output winding being wound on the legs in a transformer-coupling manner to the input winding, and a control winding being wound on the first and third legs in an orthogonal coupling manner with the first winding, and a second core joined to one of the common base plates of the first core to form a magnetical loop with a coil being wound thereon.
Claims4
A transformer for voltage regulators comprising:
- a first core means having first, second, third and fourth legs and two common portions which are magnetically joined to said four legs;
- a primary winding wound on said first and second legs;
- a secondary winding wound on the legs in such a manner that alternating magnetic flux is transferred from said primary winding to said secondary winding;
- a control winding wound on said first and third legs in such a manner that no alternating flux is transferred from said primary winding to said control winding;
- a second core means joined to one common portion of said first core means to form a magnetic loop therein;
- and
- a coil means wound on said magnetic loop of the second core means.
