摘要： A circuit arrangement is disclosed comprising a converter for converting a three-phase system of sinusoidal voltages into three trapezoidal control voltages for controlling control units serving three direct cycloconverters. More particularly, in accord with the invention, the converter acts on the sinusoidal control voltages such that during each region from .pi./3 to 2.pi./3 of a half-wave of each particular voltage that voltage is reduced to .sqroot.3/2 times its peak value, while the other two voltages are amplified or increased by an amount equal to the difference between the aforesaid peak value and .sqroot.3/2 times such peak value.

摘要： A circuit arrangement is disclosed comprising three direct converters which are fed from an a.c. voltage network. The converters are arranged in a Y configuration and are connected to a three-phase load. To increase the transmitted power and to vary the reactive power requirement, the circuit arrangement is provided with means for generating a control voltage for the control unit of at least one of the three converters such that the output voltage of this converter has a periodic waveform which includes essentially no fifth and seventh order harmonics. Additionally, the load-side conductor currents of the three converters are controlled with control signals having sinusoidal waveforms. A particular form used for the control voltage is a trapezoidal waveform.

摘要： A drive for a rotating field machine which has two AC voltage integrators of identical design for forming two electric voltage signals each of which is proportional to a flux component in the machine. Each voltage integrator includes an integrator and a zero-controller having negative feedback for suppressing the DC component of input voltages fed to a summing point of the integrator. Each integrator, is fed, as one input voltage, a voltage proportional to the phase-voltage belonging to the flux component and a voltage proportional to the corresponding stator current in a machine supply lead, for compensating the ohmic stator voltage drop. A second voltage, also depending on the phase current, is processed to compensate for the inductive stator voltage drop. To ensure optimum converter and machine utilization over an increased speed control range by reducing the phase errors of the determined flux components, each zero-controller includes a proportional controller and an integrated controller having output signals fed to the summing point. The output signal of the integrator, corrected for the ohmic stator voltage drop and the inductive stray voltage, is fed, weighted proportionally to the frequency of the machine, to the input of the proportional controller, and weighted proportionally to the square of the frequency, to the input of the integrated controller, the weighting factor having a maximum value of 1.

摘要： A three-level inverter, in which the upper and lower half of each phase relieves the semiconductor switching elements from excessive values of the rate of rise of the recurring positive forward blocking voltage. This is done with a circuit arrangement in each half has a wiring diode, a switching off relief capacitor, a further wiring diode, a storage capacitor and a discharging resistor serving as the d-c load. Additional energy feedback devices feed back, into the supplying d-c voltage source, energy which is produced in the switching-off process and is temporarily stored in the circuitry.

摘要： A system for controlling the current of a direct converter or a pulse inverter having m subconverters, each such subconverter having two outputs. One of the outputs is connected to a neutral point of the converter, and not to a load. The other output of each subconverter is provided with a separate current regulator, and connected to the load. Divergence between the voltage of the neutral point of the converter and the neutral point of the load is prevented by providing a controller with a resistive feedback line.

摘要： This invention concerns a procedure to operate a turn-off thyristor which can be set to a current-conducting state or a current-blocking state as a function of a switch-on command or a switch-off command. To permit particularly reliable and optimal operation of the turn-off thyristor, the voltage between its gate terminal, G, and its cathode terminal, K, is detected and when it drops below a negative threshold current value U.sub.GKS, a status signal, Z, is generated which indicates the current-blocking state of the turn-off thyristor. A further embodiment detects the gate current of the turn-off thyristor and after the appearance of the switch-off command, the status signal is generated as the polarity changes in accordance with the time derivative of the gate current. An overload of the turn-off thyristor is best recognized by having simultaneous to the appearance of the switch-off command, a time function with a preset expiration time initiated, and having a malfunction notification signal, F, generated for protective ignition of the turn-off thyristor if the time function expires prior to the appearance of the status signal.

摘要： Apparatus for controlling a salient-pole machine includes a stator current control element to make the stator current i.sup.S follow preset desired values i.sub..phi..sup.S*. A field current control element develops from preset desired flux values .psi.*, from the flux signal output of a flux computer (direction .phi..sub.L) and from an inductance parameter (the shunt inductance X.sub.q of the machine) a fictitious field current value signal i.sub.O.sup.E*, which represents the field current value which would be used to control a hypothetical nonsalient-pole machine. This signal i.sub.O.sup.E* is modified by a correction factor derived from the product of the longitudinal component of the flux .psi..sub.d (from the flux computer) and the different between the reciprocals ((1/X.sub.q)-(1/X.sub.d)) of the shunt and series inductances of the machine, to give a field current control signal that accounts for the asymmetry of the salient-pole machine.
