Description
Schaltanordnung für Einphasenwechselstrom Die Erfindung betrifft eine Schaltordnung für Einphasenwechselstrom. Erfindungsgemäß enthält eine Wechselstromleitung eine Reihenschaltung eines elektrischen Speichergliedes mit einer an sich bekannten Gegenparallelschaltung eines urigesteuerten Ventils und eines gesteuerten Ventils. Das Speicherglied kann vorzugsweise ein Kondensator sein. Der Kondensator wird während einer Halbwelle des Wechselstromes über das urigesteuerte Ventil aufgeladen und während der folgenden Halbwelle über das gesteuerte Ventil in Abhängigkeit von der Impedanz des Strompfades und der Stromführungszeit des gesteuerten Ventils mindestens teilweise entladen. Die Anordnung kann beispielsweise als Schalter für einen Wechselstromverbraucher verwendet werden oder als Schalter, mit dem der Kondensator in Abhängigkeit von dem leitenden oder nichtleitenden Zustand des gesteuerten Ventils an eine Wechselstromquelle angeschlossen bzw. von ihr getrennt werden kann.Switching arrangement for single-phase alternating current The invention relates to a Circuit arrangement for single-phase alternating current. According to the invention contains an alternating current line a series connection of an electrical storage element with a known per se Counter-parallel connection of a traditionally controlled valve and a controlled valve. The storage element can preferably be a capacitor. The capacitor is during a half-wave of the alternating current charged via the traditionally controlled valve and during the following half-wave via the controlled valve depending on the Impedance of the current path and the current conduction time of the controlled valve at least partially discharged. The arrangement can, for example, be used as a switch for an alternating current consumer can be used or as a switch that allows the capacitor to depend on the conductive or non-conductive state of the controlled valve to an AC power source can be connected or disconnected from it.
Zur weiteren Erläuterung der Erfindung soll auf die Zeichnung Bezug genommen werden.To further explain the invention, reference should be made to the drawing be taken.
F i g. 1 zeigt die Schaltanordnung für einen Einphasenwechselstromverbraucher, in F i g. 2 ist die Anwendung der Erfindung als Anlaufschaltung für einen Einphasenwechselstrommotor dargestellt.F i g. 1 shows the switching arrangement for a single-phase alternating current consumer, in Fig. Figure 2 is the application of the invention as a starting circuit for a single phase AC motor shown.
Nach F i g. 1 ist eine Wechselstromeingangsklemme 1 über einen Verbraucher 3 mit einem Ende eines Gleichrichters, beispielsweise einer Halbleiterdiode 4, verbunden. Die andere Klemme der Diode 4 ist über einen Kondensator 5 mit einer weiteren Wechselstromeingangsklemme 2 verbunden. Gegenparallel zur Diode 4 ist ein gesteuertes Gleichrichterelement 6 vorgesehen, dessen Steuerelektroden über Klemmen 8 und 9 an einen .Steuerstromkreis angeschlossen sind. Das gesteuerte Gleichrichterelement 6 kann vorzugsweise ein gesteuerter Halbleitergleichrichter sein, der durch einen Zündstrom über die Steuerelektroden 8 und 9 durchlässig wird und der gesperrt wird, wenn der Laststrom durch Null geht.According to FIG. 1 is an AC input terminal 1 across a load 3 connected to one end of a rectifier, for example a semiconductor diode 4. The other terminal of the diode 4 is connected to a further AC input terminal via a capacitor 5 2 connected. In opposite parallel to the diode 4 is a controlled rectifier element 6 is provided, the control electrodes of which are connected to a control circuit via terminals 8 and 9 are connected. The controlled rectifier element 6 can preferably be a controlled semiconductor rectifier, which is triggered by an ignition current over the control electrodes 8 and 9 becomes permeable and which is blocked when the load current goes through zero.
Zur Erklärung der Wirkungsweise der Anordnung soll das Ventil 6 in nichtleitendem Zustand sein, und die Halbwelle des Wechselstromes soll beginnen, wenn die Klemme 1 positiv ist gegenüber 2. Der Kondensator 9 ist über den Verbraucher 3 auf ein vorbestimmtes Potential aufgeladen, das abhängig ist von der Größe der Last 3. Am Ende dieser Halbwelle ist das Ventil 6 immer noch gesperrt. Nach der Aufladung des Kondensators 5 fließt über den Verbraucher 3 auch während der folgenden Halbwellen kein Strom, solange das Ventil 6 gesperrt ist. Wird das Ventil 6 durch einen Zündimpuls über die Klemmen 8 und 9 während einer Halbwelle gezündet, in welcher die Klemme 2 positiv ist gegenüber der Klemme 1, so wird der Kondensator über die Last 3 mindestens teilweise entladen und während der nächsten Halbwelle wieder aufgeladen. Infolgedessen kann der Wechselstrom im Verbraucher 3 durch Änderung der Stromführungszeit des gesteuerten Ventils 6 während der entsprechenden Halbwelle des Wechselstromes gesteuert werden.To explain the mode of operation of the arrangement, the valve 6 in be non-conductive, and the half-wave of the alternating current should begin, when terminal 1 is positive compared to 2. The capacitor 9 is over the consumer 3 charged to a predetermined potential, which is dependent on the size of the Load 3. At the end of this half-wave, valve 6 is still blocked. After Charging of the capacitor 5 flows through the consumer 3 also during the following Half-waves no current as long as the valve 6 is blocked. If the valve 6 is through an ignition pulse ignited via terminals 8 and 9 during a half-wave in which the terminal 2 is positive compared to the terminal 1, so the capacitor is on the Load 3 at least partially discharged and recharged during the next half-wave. As a result, the alternating current in the consumer 3 can be changed by changing the current conduction time of the controlled valve 6 during the corresponding half-wave of the alternating current being controlled.
In F i g. 2 wird der Kondensator 5 als Anlaufkondensator eines Motors 12 mit einer Anlaufhilfswicklung 10 und einer Betriebswicklung 11 verwendet. Während des Betriebes dieser Anordnung wird der Kondensator 5 über die Wicklung 10 lediglich aufgeladen und hat als Anlaufkondensator keine Wirkung, solange das gesteuerte Ventil 6 gesperrt ist. Sobald das Ventil 6 gezündet wird, fließt über den Kondensator 5 und die Motorwicklung 10 ein Wechselstrom, und somit ist der Kondensator 5 in bekannter Weise als Anlaufkondensator wirksam.In Fig. 2, the capacitor 5 is used as the starting capacitor of a motor 12 with an auxiliary starting winding 10 and an operating winding 11 are used. While the operation of this arrangement, the capacitor 5 via the winding 10 is only charged and has no effect as a starting capacitor as long as the controlled valve 6 is blocked. As soon as the valve 6 is ignited, flows through the condenser 5 and the motor winding 10 is an alternating current, and thus the capacitor 5 is known in FIG Way effective as a starting capacitor.
In sonstigen Anwendungsfällen der Erfindung als Kondensatorschalter kann es unter Umständen wünschenswert sein, daß der Kondensator in einen Stromkreis eingeschaltet oder aus dem Stromkreis herausgetrennt wird, wenn die Wellenform der Eingangsgröße sich im Nullwert befindet, um unerwünschte Schaltwirkungen im Stromkreis zu vermindem oder zu beseitigen. Die hier vorgeschlagene Schaltanordnung kann als Zündeinrichtung vorteilhaft verwendet werden zu dem Zweck, das gesteuerte Ventil in Abhängigkeit vom Verlauf der Eingangsgröße zu steuern.In other applications of the invention as a capacitor switch It may be desirable to have the capacitor in a circuit is turned on or removed from the circuit when the waveform of the Input variable is in the zero value to avoid unwanted switching effects in the circuit to diminish or eliminate. The switching arrangement proposed here can be used advantageously as an ignition device for the purpose of the controlled To control the valve depending on the course of the input variable.
