Abstract: A static converter composed of a converter-transformer and a rectifier bridge connected thereto has a bypass member connected in parallel with the bridge. Two series-connected rectifiers in one phase of the bridge constitute a bypass path. A direct voltage source can be connected with said two bypass rectifiers, the source having such a polarity as to furnish a current in the conducting direction of the two rectifiers.

Abstract: A chain of series-connected semiconductor rectifiers has a voltage divider connected in parallel therewith. A firing circuit is connected on the one hand to the control electrode and to one of the main electrodes of each rectifier and on the other hand to two different points on the voltage divider. The firing circuit derives a control voltage between such points, which is fed to the rectifier by a switching means, such as an optically controlled semiconductor.

Abstract: In combination with two AC networks, there is at least one converter connected to one of the networks which is composed of diodes and at least one other converter composed of controlled rectifiers. A further converter composed of controlled rectifiers is connected to one of the networks. All the converters are connected in series in one or several DC circuits. The further rectifier is controlled by the current in the DC circuit in such a way as to compensate for variations in the direct current therein. It is possible to connect the converters alternatively to either of the AC circuits.

Abstract: In a static converter with thyristor-rectifiers, a protection against auto-ignition includes an arrangement for sensing the polarity over the rectifier, and an And-gate. The sensing arrangement emits a first signal to the And-gate when a voltage after a commutation becomes negative and a second signal when a voltage after a commutation becomes positive. The And-gate is connected to the ignition system of the rectifiers to supply both signals thereto. The connecting means for the first signal includes a delay device which delays the signal by a time corresponding to the longest recovery time for the thyristors, so that, if the second signal is emitted during this time, an ignition signal is allowed to pass the And-gate.
Abstract translation: 在具有晶闸管整流器的静态转换器中，防止自动点火的保护包括用于感测整流器极性的安排和与门。 当换向之后的电压变为负时，感测装置向And-gate发射第一信号，当换向之后的电压变为正时，感测装置发出第一信号。 和门连接到整流器的点火系统以向其提供两个信号。 用于第一信号的连接装置包括延迟装置，该延迟装置将信号延迟与晶闸管的最长恢复时间相对应的时间，使得如果在该时间期间发射第二信号，则允许点火信号通过And -门。
