摘要： An arrangement for electrically heating a semiconductor rod which is simultaneously growing by means of materials deposited from a gas phase, wherein the heating current circuit is formed by a heating current source and an electronic switch which is controllable by a variable auxiliary voltage. The heating current is applied to a smoothing circuit by way of a rectifier circuit which is coupled with the heating current circuit. The initial voltage of the smoothing circuit is compared with a desired voltage and the difference voltage determined by this comparison serves to control the generator which supplies the auxiliary voltage. The smoothing circuit is coupled with a preamplifier whose output is connected with the movable tap of a potentiometer. A fixed terminal of the potentiometer is connected to a source which supplies the desired voltage and to the input of a subsequent control amplifier. Another fixed contact of the potentiometer is connected in a feedback circuit to the input of the preamplifier.

摘要： MOSFET and IGBT components protected against overvoltage by a limiting diode inserted between drain or, respectively, collector terminal and gate terminal are provided. A freewheeling diode connected to the component having a limiting diode with a breakdown voltage that is lower than the breakdown voltage of the freewheeling diode by a defined amount is provided. This over-voltage protection can be achieved in a simple way by integrating the limiting diode into the semiconductor body of the freewheeling diode and by a corresponding arrangement of the anode zone of the limiting diode.

摘要： In a circuit configuration for the shutoff of a semiconductor component in the event of excess current, the semiconductor component has gate and cathode terminals and is controlled by the field effect. A controllable switch is connected between the gate and cathode terminals and is made conducting by a control signal. A device controls the controllable switch to a range of high on-state DC resistance when there is excess current and a shutoff signal is simultaneously present.

摘要： By coupling the molten zone of a semiconductor rod, which is subjected to a crucible-free zone melting operation, to the operating coil used for inductively heating the molten zone, the frequency of the generator energizing the coil is determined. At constant geometry, this frequency is a measure of the molten zone volume and can be used for control purposes. A high-frequency cable disposed between the generator and the operating coil is fully matched, so that substantially only effective power has to be transmitted.
