Abstract
In accordance with the invention there is also provided a voltage combiner (200) comprising: a transformer (104) having a first (108) and second (110) winding each having a first and second tap; and an inductor (120) connected between the first and second taps of the second winding, wherein: the first tap of the first winding is adapted for connection to a first voltage (114), the first tap of the second winding is adapted for connection to a second voltage (102), and the second tap of the second winding is adapted to provide an output being the first and second voltages combined, and further wherein: the inductor (120) is adapted to provide a bypass path for the current associated with the second voltage.

Claims22
An apparatus comprising:
- a transformer comprising at least one winding, wherein said at least one winding has a first tap and a second tap;
- and
- an inductor having a first terminal coupled to said first tap, and a second terminal coupled to said second tap.
A voltage combiner comprising:
- a transformer having a first and second winding each having a first and second tap;
- and
- an inductor connected between the first and second taps of the second winding,
- wherein:
- the first tap of the first winding is adapted for connection to a first voltage, the first tap of the second winding is adapted for connection to a second voltage, and the second tap of the second winding is adapted to provide an output being the first and second voltages combined,
- and further wherein:
- the inductor is adapted to provide a bypass path for the current associated with the second voltage.

(canceled)
A method of reducing DC current in a winding of a transformer, the method comprising:
- applying a voltage including a DC component to a first tap of the winding;
- and
- providing an inductor coupled between the first tap and a second tap of the winding;
- wherein a proportion of the DC component of the voltage is bypassed around the transformer through said inductor.
