ABSTRACT:
A transformer includes at least two magnetically coupled cores with a common axis. The cores have cross sectional configurations transverse to the common axis which are not rectangular. An exciting voltage is to be applied across a first winding provided on one of the cores. A second winding provided on one of the cores includes first and second terminals across which a voltage is to be induced in response to the exciting voltage. A first device provides a relatively higher impedance between the first and second terminals of the second winding. The first device is coupled between the first and second terminals. Third, fourth and fifth windings have respective first and second terminals. The third and fourth windings are wound on one of the cores with a first polarity. The fifth winding is wound on one of the cores with a second polarity opposite to the first polarity. A second device provides a relatively higher impedance between the terminals of at least one of the third winding; the fourth winding; and, the fifth winding. One terminal of each of the second, third, fourth and fifth windings is adapted for coupling to a relatively lower impedance.
