Abstract

An electrical system comprises a generator and a control device coupled with the generator and operable to control electrical current through the electrical system via a switch module. The control device determines a loss of symmetry between two alternating phase signals generated by a first and second phase windings of a single or multiple stator generator. Specifically, the control device determines a first and second average values of two of the two or more alternating phase signals and operates to control electrical current distribution throughout the electrical system, via one or more switch modules, when the first average value differs from the second average value by a predetermined value. The control device may be further configured to sense average magnitudes of the electrical current in either direction between two electrical components, coupled with a switch module, and switch on/off the electrical current in either direction, via the switch module, to insure that the average magnitude of electrical current between the electrical components in either direction does not exceed one or more default average magnitudes.
