Abstract
A series injection device includes a power splitter coupled to two or more lines of an AC power system. The power splitter includes a coupling transformer for each phase of a single phase or polyphase AC circuit that includes the two or more lines. Each of the coupling transformers couples one of the phases of the two or more lines. The power splitter is configured to inject a first voltage of a first polarity into one or more of the two or more lines and inject a second voltage of a second polarity opposite the first polarity into at least one of the two or more lines via the same coupling transformers used to inject the first voltage. The first and the second voltages are controllable, and may or may not be independently variable.
