First Claim
Patent Images
1. A balancing bridge module comprising:
- a magnetic core;
an intra-module pair of windings around the core, each to couple to a separate voltage source; and
at least one inter-module winding around the core to couple to an adjacent balancing module;
wherein each of the intra-module and inter-module windings has an equal number of turns and operates to balance voltages between the separate voltage sources and an adjacent module if coupled.

Abstract
A balancing bridge module includes a magnetic core, an intra-module pair of windings around the core, each to couple to a separate voltage source, and at least one inter-module winding around the core to couple to an adjacent balancing module. Each of the intra-module and inter-module windings has an equal number of turns and operates to balance voltages between the separate voltage sources and an adjacent module if coupled.

19. A method, comprising:
-
balancing, in a first module, a first intra-module voltage among multiple voltage sources; providing an inter-module balancing current to a second module; and balancing, in the second module, a second intra-module voltage among multiple other voltage sources; wherein the balancing in the second balancing module includes using the inter-module balancing current.
