摘要： A circuit arrangement for feeding a single-phase or multi-phase load from a sinusoidal alternating voltage energy supply mains which carries an at least having a frequency for which the load has a substantially resistive behavior. The circuit arrangement includes a full-wave rectifier stage for deriving a substantially sinusoidal intermediate circuit voltage, a modulation stage, for example, a single-phase or multi-phase inverter, which generates from the intermediate circuit voltage, under the control of a control signal whose frequency is high relative to the frequency of the mains alternating voltage, at least one high-frequency supply voltage which is applied to the load. The supply voltage (voltages) is determined from the product of the control signal and the intermediate circuit voltage. A high-frequency filter stage is coupled to the full-wave rectifier stage so as to suppress interference induced into the energy supply mains in a frequency range which includes the frequency of the control signal. This simple circuit arrangement ensures a mains current containing few harmonics.

摘要： A controller is described, which is particularly suited for a power supply with switching elements (S1, S2), such as a switching mode power supply. The controller comprises a logical unit (18) which calculates a binary state value Zk by a first logical operation from a binary input value I and a prior binary state value Zk−1. The logical unit further calculates a binary output value Y by a second logical operation from the binary input value I and the binary state value Zk. In this way, fast and efficient fully digital control may be realized especially for a switching mode power supply, where the binary input value I is a comparator value and the binary output value Y is used to drive the switch elements (S1, S2). An adaptation unit (20), which may be a signal processor, determines the logical operations and delivers them to the logical unit (18) during operation of the controller unit (16).

摘要： The invention relates to an electronic circuit and to a method of supplying a high-pressure discharge arc lamp (12). The circuit comprises a DC-AC converter, for which purpose two controllable switching elements T1, T2 are connected in the form of a half bridge to an operating potential U+ and a reference potential (10). The circuit further comprises a two-stage filter arrangement. The lamp is connected to a coil Lign of the second filter stage, and the same connection terminal of this coil Lign is connected to the reference potential (10) via a capacitor Cign. To make the circuit as small and as economical as possible, while high high-frequency interference peaks and strong currents in the circuit are avoided, it is proposed that a coil Trfilt of the first filter stage has at least three taps. The first, outer tap is connected to the output of the half bridge, the second, central tap to the second connection terminal of the coil Lign, and the third, outer tap to the reference potential (10) via a capacitor Cfilt.

摘要： The invention relates to an axial-flow induction motor comprising a stator having a winding arranged in a slot and a rotably supported laminated rotor which is spaced from the stator by an air gap. The rotor has a magnetically highly conductive layer on the side which is remote from the stator and an electrically highly conductive layer on the side which faces the stator. In order to reduce losses caused by harmonics, the rotor also includes an additional magnetic conductive layer between the electrically highly conductive layer and the air gap. The magnetic conductivity of the additional magnetic conductive layer in the direction of rotation is low in comparison with the magnetic conductivity of the magnetically highly conductive layer. The electrically highly conductive layer is also thicker than the magnetically conductive layer.

摘要： An apparatus and method for determining an output voltage or output current in an SMPS circuit 10 are described. The SMPS circuit comprises a switching element 18 which in operation is switched according to consecutive switching cycles. An electrical value IL within the SMPS circuit 10 is compared to a reference value Iref. The electrical value IL varies within the switching cycle such that is equal to the reference value at least once during each cycle. The comparator signal comp is evaluated to determine timing information t of an instant of change in the signal. The timing information t is used for determining the output voltage Vout,Av or output current Iout,Av.
