Methods to form and operate multi-terminal power systems

Title: Methods to form and operate multi-terminal power systems

A method for forming and operating a multi-terminal power system, includes: connecting multiple sending terminals to a network of a power system; and local control of each sending terminal to behave as a constant-power source such that both output voltage and output current of the sending terminal may simultaneously vary in response to changing external circuit conditions while maintaining constant a product of the output voltage and the output current of the sending terminal. At least one sending terminal may include a capacitive output converter having a capacitor connected between two output terminals and a controlled current source connected in parallel to the capacitor, or an inductive output converter having an inductor connected to an output terminal and a controlled voltage source connected in series with the inductor.

Systems and methods for multi-fluid geothermal energy systems

Patent Buscheck, Thomas A.

A method for extracting geothermal energy from a geothermal reservoir formation. A production well is used to extract brine from the reservoir formation. At least one of nitrogen (N.sub.2) and carbon dioxide (CO.sub.2) may be used to form a supplemental working fluid which may be injected into a supplemental working fluid injection well. The supplemental working fluid may be used to augment a pressure of the reservoir formation, to thus drive a flow of the brine out from the reservoir formation.

Semiconductor systems utilizing materials that form rectifying junctions in both N and P-type doping regions, whether metallurgically or field induced, and methods of use

Patent Welch, James D.

Disclosed are semiconductor systems, such as integrated circuits utilizing Schotky barrier and/or diffused junction technology, which semiconductor systems incorporate material(s) that form rectifying junctions in both metallurgically and/or field induced N and P-type doping regions, and methods of their use. Disclosed are Schottky barrier based inverting and non-inverting gate voltage channel induced semiconductor single devices with operating characteristics similar to multiple device CMOS systems and which can be operated as modulators, N and P-channel MOSFETS and CMOS formed therefrom, and (MOS) gate voltage controlled rectification direction and gate voltage controlled switching devices, and use of such material(s) to block parasiticmore »« less

Methods, systems and apparatus for optimization of third harmonic current injection in a multi-phase machine

Patent Gallegos-Lopez, Gabriel

Methods, system and apparatus are provided for increasing voltage utilization in a five-phase vector controlled machine drive system that employs third harmonic current injection to increase torque and power output by a five-phase machine. To do so, a fundamental current angle of a fundamental current vector is optimized for each particular torque-speed of operating point of the five-phase machine.
