1. An apparatus for bidirectionally converting electrical power from a first power source to a second power source in a single conversion stage, where in
the first power source is either a single phase power source of a first alternating current frequency and amplitude or a direct current power source of a first voltage level and polarity, and,
the second power source is either a single phase power source of a second alternating current frequency and amplitude or a direct current power source of a second voltage level and polarity, where in
the first power source can be an input power source and the second power source can be an output power source in one direction, and the second power source can be in the input power source and the first power source can be the output power source in the reverse direction, where in
the first power source is connected to a first port of a bidirectional variable gain power conversion circuit operable by a remotely programmable controller and the second power source is connected to a second port of the bidirectional variable gain power conversion circuit operable by the remotely programmable controller, where in
the remotely programmable controller operates the bidirectional variable gain power conversion circuit to convert power from the input power source to the output power source providing a desired alternating current frequency and amplitude or providing desired direct current power voltage level and polarity, in a series of predetermined operational states wherein
the operational states can be modified or added or commissioned or decommissioned by the remotely programmable controller to provide power conversion functions, without the need of external modules.
