Abstract
An improved power transfer mechanism is disclosed, which is particularly beneficial in power transmission applications. The mechanism allows the SCFCL system to have more than one electrical reference. The use of hydraulic power simplifies the design of systems in which one part of the system is referenced to ground, while a second part of the system is referenced to a different voltage, typically much higher than ground. For example, the tank of the SCFCL system may not be connected to ground, while hydraulic power supply is referenced to ground. This embodiment is performed without the use of an electrically conductive path between the two parts of the system.
