Inertial energy storage system and hydrofluoroether power transformer scheme for radar power system and large scale PFN charging

摘要

A multi-port storage system includes a dynamo-electric machine with integral rotor inertia forming a primary energy storage system. The dynamo-electric machine has a primary stator winding configured to accept multiple AC input power sources, and has at least two secondary stator windings configured to deliver electric power to multiple loads at different power, frequency and voltage levels. A secondary energy storage system is coupled to the primary energy storage system, and is configured to convert its stored energy to electric power. The dynamo-electric machine is configured to enhance and buffer the secondary energy storage system, and is configured to improve the conversion of the stored energy to electric power. The system may include a step-up transformer responsively coupled to one of the secondary stator windings. The step-up transformer may comprise a single phase or polyphase step-up transformer having internal cooling and electrical insulation between the secondary windings comprising a hydro-fluoro-ether (HFE) vapor and liquid fluid.
