    • Apertures through each face of a planetary rotor, volutes for low loss delivery and collection of fluid to and from the working volumes of a planetary rotary pump, compressor, or turbine, and zero clearance seals by using continuous carbon fiber reinforced polyetheretherketone (PEEK) or other self-lubricating materials significantly improve the volumetric flow rate of such rotary pumps compressors or turbines. By establishing a means to vent each working volume to an intake or exhaust port at arbitrary rotor positions, apertures linking working volumes to intake or exhaust ports allows each working volume of a multilobe planetary rotary pump to function independently near peak volumetric efficiency. An additional means to improve the performance of planetary rotary pumps has been established by using scroll-like volutes which collect and deliver the exhaust and intake flow for each working volume in a manner which reduces the fluid dynamic loss associated with conventional sudden expansions and contractions found at the inlet and exit of a plenum. To minimize leakage between the separate working volumes and improve performance, self lubricated continuous carbon fiber reinforced polyetheretherketone seals are employed for components in high speed sliding contact. The continuous carbon fiber reinforced PEEK can withstand high sliding speeds, high temperatures with low wear and excellent foreign object impact resistance.

    • A power system architecture for a spacecraft and a method of a power supply for a spacecraft are presented which take advantage of the reduced plasma interaction associated with positive ground high voltage photovoltaic arrays and provide a negative ground power supply for electrical loads of the spacecraft. They efficiently convert and regulate power to the load bus and reduce power system mass and complexity. The system and method ground the positive terminal of the solar arrays to the spacecraft hull, and using a power converter to invert the electric sign, permit a negative ground for the electrical distribution bus and electrical components. A number of variations including a load management system and a battery management system having charging and recharging devices are presented.

    • Various three, four and five terminal power supply control packages for controlling delivery of power from a source to a load in both single and dual switch transformer coupled power converters are disclosed. By way of example, a three-terminal control package has a first terminal for coupling to a primary winding of a transformer, a second terminal for coupling to a ground reference and a third terminal for coupling to a source of operating power. An internal power switch has an input coupled to the first terminal, an output coupled to the second terminal, and an activation gate. The package includes pulse train control circuitry coupled to the power switch activation gate and responsive to an error signal for driving the power switch, the error signal derived from an internally generated compensation signal corresponding to an expected voltage loss between the source and the load.
