摘要： Inductive rotary joint system with stationary and rotating sides has a one-phase rectifier for receiving a one-phase AC-input to generate low-level DC-voltage, and a three-phase rectifier for receiving a three-phase input to generate higher-level DC-voltage. An AC-power generator received the DC-voltage and generates an AC-power, which is coupled by an inductive rotary joint to a load at the rotating side. When connected to the one-phase AC-input only, couples a comparatively lower voltage to the load. When connected to the three-phase AC-input, the AC-power generator couples a comparatively higher voltage to the load. A control unit at the secondary side for controlling at least the load is connected to measure the voltage produced for the secondary side, and to distinguish between a comparatively lower voltage and a comparatively higher voltage. When a presence of a comparatively higher voltage is indicated, an x-ray tube is enabled within the load.

摘要： A device for non-contacting interrogation, without auxiliary power, of system states of a part that is rotatable relative to a fixed part comprises a coil on the rotatable part and a coil on the fixed part. The coils are mutually coupled, one being fed by a signal generator generating different frequencies, whilst the other coil is supplemented with at least one capacitance to form a resonance circuit. Further impedances can be added by means of switch elements to change a resonance frequency and form an interrogation circuit. By determining a resonance frequency on a signal generator side it is possible to draw conclusions about an impedance on an opposite side and to assign this to a switch element which is closed.

摘要： A method is disclosed for compensation of system tolerances in an inductive coupler which includes a power generator that feeds an alternating current into a series resonance circuit formed by a resonance capacitor and an inductive rotating transmission device. First, a brief sequence of at least one period of an alternating current is fed by the power generator into the series resonance circuit. Then the series resonance circuit is short-circuited. A first resonance frequency is measured. Then a longer sequence having a plurality of periods of an alternating-current voltage is generated by the power generator, so that a given small voltage is built up at the load. Now a second resonance frequency is measured while the resonance circuit is short-circuited. Then at least one correcting variable for the power generator is determined from the two resonance frequencies.

摘要： A semiconductor power switch comprises at least a first IGBT and a second IGBT. The collectors of the first and second IGBTs are connected to each other, and the emitters of the first and second IGBTs are connected to each other. The first IGBT is an IGBT type with a comparatively low collector-emitter on-voltage and a comparatively high turn-on or turn-off switching energy. In contrast thereto, the second IGBT is an IGBT type with a comparatively high collector-emitter on-voltage and a comparatively low turn-on or turn-off switching energy. Both IGBTs receive gate signals from a control circuit for switching the power switch on during a first time interval and switching the power switch off during a second time interval. The control circuit is designed to supply an on-signal to the second IGBT during the whole first time interval and another on-signal to the first IGBT during only a part of the first time interval, which is less than the whole.

摘要： An inductive rotary joint for non-contact transmission of electrical energy between a stationary part and a rotating part of the rotary joint comprises a power generator for generating an alternating voltage or an alternating current, which feeds a load by means of a rotatable power transmitter. An electrical parameter on the primary side of the power transmitter is determined with a measurement means, and from this, the condition of another electrical parameter at the load is approximated by means of a functional unit. Regulation of the power generator is effected with this approximated value.
