A load control for a system comprised of a plurality of energy converters wherein increases in total energy demand from the system is compensated by increasing only the rate of energy conversion of that converter producing energy conversion at least cost and decreases in total energy demand from the system is compensated by decreasing only the rate of energy conversion of that converter producing energy conversion at highest cost.

A converter for converting a low voltage direct current power source to a higher voltage, high frequency alternating current output for use in an electrical system where it is desired to use low weight cables and other circuit elements. The converter has a first stage series resonant (Schwarz) converter which converts the direct current power source to an alternating current by means of switching elements that are operated by a variable frequency voltage regulator, a transformer to step up the v...

An ultrafast analog to digital converter is provided which uses Josephson devices. The converter has a plurality of Josephson junction interferometers. The output of each interferometer is a bit that forms part of a digital representation of a sampled analog signal. Each of the interferometers has an offset, with each offset being different. The bits output by the interferometers are weighted by the offsetting. The weighting of bits by offsetting rather than periodicity allows the use of interfe...

Damping resistance is introduced via transformer coupling into a circuit which includes an inductance-capacitance (LC) filter arrangement to smooth the current pulses applied to a load.

This invention is concerned with improving the efficiency of thermionic energy converters. The invention is particularly directed to the reduction of plasma losses in these converters. This beneficial technical effect is achieved by internal distribution of tiny shorted cesium diodes driven by the thermal gradient between the primary emitter (10) and the collector (12). Specifically, the tiny, shorted diode distribution (14) comprises protrusions of the emitter material (16) from the main emitte...

A polyphase AC/DC converter, useful as a drive for a DC motor or in a power-sharing electrical power distribution system, comprises a naturally-commutated, phase-controlled, polyphase thyristor bridge and control determining the application of firing signals to the thyristors and operable in the inversion mode of the bridge to transfer conduction of load current between phases at the conventional inversion limit defined as radians advanced from the rectification limit of the bridge, but to opera...

A load control for a system comprised of a plurality of energy converters wherein a System Control Signal proportional to system load is developed and utilized to simultaneously adjust the rate of energy conversion of each of the converters in parallel in accordance with changes in system load. The rate of energy conversion for each converter, while operating under stead-state conditions for a predetermined period of time, is readjusted until its actual incremental cost of production is equal to...

Various device embodiments include first and second plate assemblies. Each plate assembly includes a base, a seal plate and a servo motor to provide a linear motion of the seal plate with respect to the base. The device farther includes at least one plate assembly motor operably linked to the bases of the plate assemblies to provide a linear motion of the first and second plate assemblies toward each other to perform a sealing operation and away from each other. The device further includes a con...

Bilateral converters are disclosed which translate direct current voltages at one level to direct current voltages at another level. The same converter can also be used to translate direct current voltages at the second level back to direct current voltages at the first level. The converter is bilateral in the sense of converting direct current energy in both directions from a higher to a lower voltage level and from the lower to the higher level. A switching signal interrupts the direct current...
