摘要： A protection circuit for use with a thyristor having several break over diode, BOD, elements is connected between the anode and the gate of a thyristor providing static and dynamic overvoltage protection. With the exception of the BOD element connected to the gate, all the BOD elements have RC circuits connected in parallel, whose respective resistance and capacitance values are essentially identical. The BOD element connected to the gate and the cathode-gate portion of the thyristor has an additional RC circuit connected in parallel, whose resistance value is smaller or the same and whose capacitance value is smaller than the respective resistance and capacity values of the other RC circuits. Preferably, in this last RC circuit the resistance value is very small in contrast to the resistance values of the other RC circuits, and the capacitance value is negligible. In this preferred embodiment, the static actuation voltage is determined by the BOD elements not directly connected to the gate, and the dynamic actuation characteristic is determined by an equivalent series RC circuit which is determined by the capacitances of all the RC circuits and by the resistance, which is connected in parallel to the series connection of the BOD element connected to the gate and the thyristor gate-cathode portion.

摘要： A firing circuit for two antiparallel-connected power thyristors. Each of the power thyristors has a gate terminal; the gate terminals being connected by a series combination of auxiliary thyristors. Each of the auxiliary thyristors is of the type which can withstand firing resulting from excessive anode cathode potential; the sum total of the anode cathode potentials of the series-connected auxiliary thyristors being less than the anode-cathode breakdown voltages of the power thyristors. This, while a power thyristor is in a nonconductive state, an anode-cathode voltage is impressed thereacross in the forward conduction direction. At an anode-cathode voltage which is less than the breakdown voltage of the power thyristor, the auxiliary thyristors are fired so as to form a conductive path which includes the cathode-gate path of the other power thyristor, the auxiliary thyristors, and the gate-cathode path of the protected thyristor. Normal firing of the power thyristor is achieved via the auxiliary thyristors, which may be fired by light pulses or current pulses. Thus, the auxiliary thyristors perform protective and normal firing operations.

摘要： A converter valve which is constructed from modular elements is disclosed. Each of these modular elements comprises a group of thyristors arranged in side-by-side relationship and the drive means and circuit component group associated with such thyristor group. A metallic shield surrounds the thyristor group and its associated drive means and a portion of its associated component group. The shield, in turn, is supported within a metallic pressure tube which has both its ends closed off by bulkheads and is adapted to receive SF.sub.6 gas. The aforesaid bulkheads may be separate connecting members which, in addition, may also be designed as nodal elements and mechanical support points. The converter valve is constructed from a small number of the aforesaid modular elements, each element being replaceable without removing the gas from the entire valve.

摘要： This invention concerns a protective device for at least one thyristor. Separate measuring sensors are provided for determining the thyristor parameters of current and the magnitude and rising slope of the thyristor voltage. The measuring sensors are followed by a comparison stage which compares the parameters with definite, predetermined conditions, and transmits a trigger pulse for the thyristor. With the protective device according to the invention, the thyristor can be fired by means of its control electrode during the recovery time of the thyristor, if an overvoltage occurs.

摘要： Disclosed is a circuit arrangement for monitoring a thyristor via a signal transmitting device which is connected on its input side in shunt with the thyristor and to the output of which a light emitting diode is connected for sending light signals to an evaluating device. To obtain a particularly simple and therefore operationally reliable design of such a circuit arrangement, and to achieve the emission of light signals with particularly high light output, the signal transmitting device contains a rectifier arrangement followed by an integrating stage, followed in turn by a threshold voltage switch which changes to a current-conducting state as soon as the voltage drop across it exceeds a predetermined threshold value. No separate power supply is required.

摘要： A heating device for use in motor vehicles to rapidly heat combustion chambers, exhaust gas sensors, catalyzers and other associated apparatus. A resistive heating element is connected in series with a low-impedance measuring resistor and a switch across a power source, while a resistance bridge is formed with the aid of two further resistors. The diagonal bridge voltages are compared in a comparator whose output actuates a control circuit which operates the heater switch. The heater switch also provides the power for the comparator. In a first interval, constant current is applied to the heating element, while the current is pulsed during a second time interval. The switch control pulses may be provided by a free-running oscillator or one whose pulses are synchronized with the undulations of the engine starter current.
