Abstract
A balancing circuit for systems having at least first and second transformers. The transformers' primary sides are connected to one another. The transformers' secondary sides also are connected to one another. The balancing circuit includes a branch connecting one terminal on the secondary side of the first transformer and the corresponding terminal on the secondary side of the second transformer. The branch has a significant impedance such that the voltage in the secondary sides of the transformers is forced to be substantially equal. A method is also provided for performing balanced operation of a system includes at least a first and a second transformer.
