Abstract
A transformer has a first winding, a second winding and a third winding. The first winding is configured to receive a first signal. The second winding is magnetically coupled to the first winding and configured to generate a second signal through electromagnetic induction with the first winding, or by receiving a second input signal. The third winding is magnetically coupled to the second winding, magnetically isolated from the first winding, and configured to generate a third signal through electromagnetic induction with the second winding. The second winding is posited between the first winding and the third winding. The first winding is posited adjacent to the second winding, and the second winding is posited adjacent to the third winding.
Claims28
A transformer, comprising:
- a first winding, configured to receive a first input signal to generate a first signal;
- a second winding, magnetically coupled to the first winding and configured to generate a second signal through electromagnetic induction with the first winding or configured to generate the second signal by receiving a second input signal;
- and
- a third winding, magnetically coupled to the second winding, magnetically isolated from the first winding, and configured to electromagnetically induct with the second winding and output an output signal;
- wherein the second winding is positioned between the first winding and the third winding, the first winding is positioned adjacent to the second winding, and the second winding is positioned adjacent to the third winding.
A transformer, comprising:
- a first winding;
- a second winding;
