摘要： A method is provided for compensating the flux drift caused by measurement and/or calculation errors when controlling a rotating electrical machine. The flux drift of the estimated flux vector may be compensated for by comparing the length of the flux vector with a reference flux magnitude which already has been determined for controlling the inverter. Depending on the comparison, the length of the estimated flux vector may be lengthened or shortened.

摘要： A method and an apparatus for direct torque control are specified for a three-phase machine fed via a harmonic filter, which method manages as far as possible without any major adaptation to already known DTC methods and DTC apparatuses. In addition, the oscillations caused by the filter are intended to be damped effectively. This is achieved in that a current flowing through the filter and/or a filter output voltage are/is measured, and the reference flux value and the reference torque value are corrected on the basis of the measured voltage and/or of the measured current. The correction comprises a transformation of the filter output voltage into a first component at right angles to a stator flux and into a second component parallel to the stator flux, as well as a reduction in the reference torque and flux values in proportion to the oscillating part of the filter output voltage.

摘要： A voltage converter having a voltage intermediate circuit and an invertor connected to the output of the voltage intermediate circuit. The invertor produces a three-phase AC voltage at its output and is connected to the output terminals of the voltage converter by a filter arrangement. The filter arrangement includes a filter inductor connected in series with the output terminal and the filter capacitor connected between the output terminal and a common capacitor star point. Attenuation of the DC system is achieved by having the capacitor star point connected to the voltage intermediate circuit by way of an RC element having a capacitor and a resistor.

摘要： A converter circuit arrangement having a DC intermediate circuit (3) includes a transformer (8) having at least two windings (9 and 10). This transformer (8) is connected in the intermediate circuit (3) such that the undesirable, unbalanced current components lead to magnetization of the transformer core and are thus reduced. A grounded LC filter (Lf, Cf) is connected upstream of the load (6) and produces a sinusoidal voltage across the load (6). In consequence, the circuit can be used with any desired rotating-field machines, and thus also for retrofitting existing systems.
