Abstract
A transformer power combiner includes a plurality of current combiners and a voltage combiner. The current combiners are coupled in series, and include a plurality of primary winding conductors magnetically coupled to a plurality of secondary winding conductors respectively. Each of the current combiners is configured to combine currents flowing therethrough. The voltage combiner is coupled to a series connection of the current combiners, and is configured to combine voltages across the current combiners to thereby generate an output of the transformer power combiner.
Claims5
A transformer power combiner comprising:
- a plurality of current combiners coupled in series, the current combiners comprising a plurality of primary winding conductors and a plurality of secondary winding conductors magnetically coupled to the plurality of primary winding conductors respectively, wherein a current combiner of the plurality of current combiners combines currents flowing the corresponding secondary winding conductors;
- and
- a voltage combiner, coupled to a series connection of the current combiners, the voltage combiner being configured to obtain a sum of voltages across the current combiners to thereby generate an output of the transformer power combiner.
