Abstract: An assembly and a method determine the angular position of a rotating machine by way of an inductive sensor. From the excitation signal for a primary winding of a sensor and voltages induced in the two secondary windings of the sensor, three more signals are derived using phase shifters and polarity sign determination units. The six signals in total are sampled using a sample and hold sampling unit and provided to a processor for evaluation, which then calculates the current angular position of the rotating machine at the sampling time.

Abstract: The invention relates to an electrical power distribution apparatus (100) connectible to one or more loads (119). The electrical power distribution apparatus (100) comprises inter alia one or more taps (112) for supplying the loads (119) with electrical power. On top of circuit breakers (108) to switch off the power supply in order to protect the loads against damage, there is also arranged a second layer of soft fuse switches (110) which are arranged to switch on or off the power supply at the taps (112) to control distribution of the power. The soft fuses (110) operate in dependence on and in response to commands issued from a controller (105) which in turn operates and issues those commands in response to and independence on the voltages and amperages monitored at those taps (112) by way of a monitoring module (111). Switching on/off occurs at amperage and voltages lower than the critical threshold values to which the circuit breakers (108) respond to.

Abstract: A method diagnoses current sensors of an n-phase induction machine which has n?1 current sensors. The n phases of the induction machine are short-circuited for a brief period of time during normal operation of the induction machine, and the time progressions of the n?1 currents are measured by the n?1 current sensors during the short-circuit operation. The actual values of the time progressions of the n?1 measured short-circuit currents are compared to corresponding prescribed target values for the n?1 short-circuit currents. A potential fault state of one or more current sensors is determined from the comparison.

Abstract: A power supply power supply (30) comprising a DC voltage supply, a control unit and a plurality of high voltage channels (33a-33d) is suggested. Each high voltage channel (33) includes an inverter (IKTV), a resonance circuit, a transformer (TR), and a rectifier (RECT). The resonance circuit cooperates with the inverter (INV). The inverter (INV) is formed by a first switching unit and a second switching unit whereby a voltage of a first polarity can be applied to the resonance circuit in a first switching state, whereas a voltage of a second polarity can be applied to the resonance circuit in a second switching state. The switching states can be switched by the control unit in such a manner that in a first mode of an operation for high output power, the output power can be adjusted by changing the switching frequency in the range of the resonance frequency.

The rectified secondary voltage of this transformer is applied to a use which requires a high short-time power in a first mode of operation and a lower continuous power in a second mode of operation. The maximum permissible continuous power can be increased by means of an auxiliary inductance Lh which is active in the second mode of operation but inactive in the first mode of operation.

Abstract: A motor whose torque is not generated by magnetic fields but rather by dielectric forces to be used in microelectronics and micromechanics. The rotors are composed of several dielectrics, which are arranged in a sector-shaped or shell-shaped manner or partially or completely envelop each other. These motors can be miniaturized down to a size of a few millimeters. They are distinguished by having slow to medium rotation speeds, short starting phases (ms range and less), extremely low current consumption, simple construction, high running constancy and being practically maintenance free. The characteristic curve of rotation (rotation as the function of the field frequency) may be selected in many ranges by changing the dielectrics of the rotor.

Abstract: A circuit arrangement comprises an inverter with two parallel switching branches which are connected to a DC voltage source and each of which comprises two series-connected switching members, each of which comprises at least one switch and an anti-parallel connected diode. A switching member in one switching branch each time constitutes a diagonal pair in conjunction with a switching member in the other switching branch. A load with a given polarity is connectable to a DC voltage source via the diagonal pair. The voltage on the load temporarily becomes zero upon the change-over from one polarity to the other. A control circuit is provided for opening and closing the switches in a manner such that the switching members are successively switched on and off.
