摘要： The present disclosure relates to electric converters. The teachings thereof may be embodied in an electric converter to transfer an electric power of more than 3 kilowatts comprising a half-bridge with at least two parallel circuits. Each of the parallel circuits includes a plurality of semiconductor switches. Each of the parallel circuits includes at least two base circuits arranged next to one another on a common printed circuit board. Each of the respective base circuits includes one of the plurality of semiconductor switches and a gate driver circuit for the semiconductor switch. Each gate driver circuit is electrically connected to a gate of the semiconductor switch by a control line. In each of the parallel circuits, a shortest control line and a longest control line differ from one another with respect to length by no more than the factor of 1.5.

摘要： A charging station for an electrically powered vehicle has a connection for an electrical energy source, an inverter and an electronic coil connected to the inverter for wireless energy-transferring coupling of the electrically powered vehicle. The inverter is configured to apply an alternating electric voltage to the electronic coil in resonant operation. The electronic coil is connected to the inverter by way of a compensating circuit with a settable passive electronic energy storage device. The compensating circuit is configured to set a frequency of the alternating voltage by means of the settable passive electronic energy storage device.

摘要： A circuit arrangement for detecting a zero crossing of an alternating current is provided. The circuit arrangement includes a load through which the alternating current can flow, and an evaluation unit connected to the load and configured to evaluate an electrical voltage formed at the load, and to determining zero currents. The load comprises a capacitor through which the alternating current or a current to be measured derived therefrom can flow, and the evaluation unit is configured to account for a phase shift caused by the capacitor for determining the zero currents.

摘要： A detector apparatus includes a number of detectors for assigned radiation sources of a computed tomography system, wherein each detector may require a constant input voltage in a range between 900 V and 1200 V. During operation of the detector apparatus, an auxiliary voltage is fed to a high voltage source to supply power to the input terminals on the number of detectors. The high voltage source includes a central first DC-DC converter, to which the auxiliary voltage is fed, and a number of second DC-DC converters arranged downstream of the first DC-DC converter. The first and the second DC-DC converter are based on different power supply topologies, wherein each second DC-DC converter generates the constant input voltage in the predetermined range from a central output voltage provided by the first DC-DC converter and supplies the constant input voltage to a corresponding detector.

摘要： The present disclosure relates to tuning oscillatory systems. The teachings thereof may be embodied in a device having an adjustable capacitance value for tuning a first oscillatory system, connectable to a second oscillatory system having an unknown and weak coupling factor. The device may include: a first capacitor having a capacitance dependent upon a voltage; and a DC voltage source having a variable voltage applied to associated terminals; a series-connected arrangement of the DC voltage source and a decoupling element connected in parallel with terminals of the capacitor, to apply a variable bias voltage to the first capacitor. The voltage applied to the terminals of the DC voltage source may depend at least in part on a working frequency of the first oscillatory system.
