摘要： An inductive load 1, more specifically a direct current motor, is fed by a direct current source through a semiconductor regulator which contains two parallel switching controllable semiconductor rectifier elements with identical conduction direction which in turn are in series with a respective one-half of center tapped output autotransformer. Parallel to the semiconductor regulator is an additional and identical semiconductor regulator. The center tap points of both semiconductor regulator autotransformers are connected with the terminals of a third output autotransformer which is similarly center tapped, whereby the center tap point of the third output autotransformer is connected to a terminal (+) of the inductive load. The control assembly is made in such a manner that it produces clock frequency signals with identical control levels for both semiconductor rectifier elements; however, these signals for the two parallel switching arrangements are, electrically offset by 90 degrees. In this way, it is possible to operate the motor in RPM ranges where a minimum of ripple current is obtainable.

摘要： Low-loss external wiring, for the switching-off relief of the semiconductor switching elements in a stage of a three-level inverter provides a switching-off relief capacitor which is connected to the stage output. Wiring capacitors are coupled to each of the upper and lower ends of the stage. The inverter also includes a diode network. Additional d-c consumers which are preferably either ohmic resistors or energy recovery devices take up energy which is interim-stored in the wiring capacitors.

摘要： The disclosure relates to an inverter comprising at least two controllable load thyristors which connect a load alternately with the poles of a feed d.c. voltage source. There is connected in parallel with each load thyristor one diode each which is a component of a commutation installation. The commutation installation manifests an LC-series oscillatory circuit dimensioned for a specified load current, and, manifests, for each load thyristor a controllable commutation thyristor which forms a closed circuit with the LC-series oscillatory circuit and its diode. The LC-series oscillatory circuit is connected to an auxiliary d.c. voltage source of a constant voltage via a reloading circuit.

摘要： The disclosure relates to an inverter comprising at least two controllable load thyristors. One diode each is connected in antiparallel fashion with each load thyristor, which diode is a component of a commutation installation for the corresponding load thyristor. The commutation installation manifests two LC-series oscillatory circuits, which are dimensioned for two different load currents. There is present for each LC-series oscillatory circuit one pair each of commutation thyristors. The two commutation thyristors of one of the two pairs, respectively, are alternately ignited such that, during the commutation of the load thyristors the commutation current can flow in a low impedance circuit.
