摘要： An uninterruptible power supply (UPS) system includes a control and display module operational with a UPS when carried by a housing of the UPS and when remote from the housing. An orientation sensing switch carried by the module senses a horizontal or vertical position of the module and provides a signal to a module processor for providing performance diagnostics of the UPS in a horizontal or vertical format as appropriate. The UPS system housing includes support arms extendable from the housing for providing added stability to the housing when in a vertical position. The control and display processor receives manual input from user buttons on the module and communicates with a UPS processor carried by the housing. The UPS includes a battery positioned within the housing for access by removal of a front housing panel for avoiding movement of the UPS system during replacement of batteries.

摘要： Power is transferred from a stationary power supply to a rotational gantry in a computer tomography (CT) system through a rotary transformer arranged in a ring configuration with an inner diameter that is sufficiently large to receive a patient. The rotary transformer has a toroidal rotor core and a toroidal stator core arranged either concentrically with an air gap extending radially therebetween or side-by-side with an air gap extending axially therebetween. A resonant inverter provides ac power to the rotary transformer which, in turn, drives a high-voltage tank circuit coupled to a x-ray tube, the tank circuit and x-ray tube being mounted on a rotational gantry. Advantageously, this is a contactless power transfer system which eliminates conventional brush and slip ring arrangements and moreover avoids the need for mounting the inverter to rotate with the CT gantry.

摘要： A power supply system for thrusters (e.g., arcjet thrusters) in a spacecraft system comprises lightweight, redundant power supplies that share the power distribution function to the thrusters. Each power supply comprises a plurality of parallel-connected power supply subunits of which the combined power output capability exceeds the required maximum power demand by at least one subunit capacity for each arcjet thruster in the system. Each power supply subunit comprises a lightweight, high-frequency, soft-switching power supply. For arcjet systems comprising arcjet thrusters that do not operate simultaneously, relays are employed to switch between thrusters.

摘要： A gradient current speed-up circuit, for use in a higher-speed NMR imaging system with a gradient power amplifier and an associated gradient coil, has an energy-storage element, with an inductance typically between 5 and 20 times the inductance of the associated gradient coil. A plurality of semiconductor switching elements receive the current output of the energy-storage element; and the associated gradient coil is connected between selected ones of these semiconductors devices. The semiconductor devices are turned on and off in selected patterns, to cause the energy-storage element current to be suddenly applied to and removed from flow through the associated gradient coil.

摘要： A low cost power control circuit which achieves variable speed, quasi four-quadrant motor control well suited to the requirements of a direct drive clothes washing machine. For handling relatively low frequency motor direction control signals (one or two Hertz), four relatively inexpensive, low frequency thyristors are employed in a four-leg bridge circuit arrangement. For handling relatively high frequency chopper duty cycle control signals (10 kHz), a single high frequency power transistor is employed. To provide quasi four-quadrant control entirely suitable for clothes washing, a fifth thyristor and a series dissipation resistor are connected across the motor terminals and switched ON during agitation just prior to each motor reversal when motor velocity is decreasing and motor back emf exceeds applied emf. A feedback servomechanism is employed to control motor rotational velocity via chopper pulse width modulation. In the feedback loop, the means for generating a signal representative of actual motor velocity preferably comprises a negative impedance converter circuit responsive both to overall voltage across the input terminals of the thyristor bridge and to current through the bridge and operable to minimize the effect of motor internal impedance to derive a signal representative of motor induced emf, and therefore representative of motor velocity, with improved accuracy.

摘要： A filament winding forms a part of the step-up transformer in a flyback-type high-frequency, high-voltage power supply for supplying filament heating energy, in addition to the anode potential supplied by a secondary winding of the transformer, to a magnetron microwave power generator, which is a self-rectifying load. The voltage across the transformer primary winding, and the current flowing through a controllable current path in a switching device connecting the series with that primary winding, are both monitored and compared to reference voltage and current values for establishing the conduction time interval of the switching device to provide active control of the power input to the load.
