Abstract
Each one of the secondary converters has a corresponding transformer having a primary winding associated with a primary alternating current (AC) signal and a secondary winding associated with a secondary alternating current (AC) signal. A secondary controller provides secondary control signals to the secondary semiconductor switches of the secondary converters with one or more time-synchronized, target phase offsets with respect to an observed phase of the alternating current signal (e.g., primary alternating current signal or the secondary alternating current signal) to provide the target phase offset (or targeted phase offsets) commensurate with or sufficient to support a required electrical energy transfer from the primary controller to the corresponding secondary controller (or secondary controllers).
