Description
Schaltungsanordnung zur Entstörung einer Phasenanschnittsteuerung eines wechselstromgespeisten Verbrauchers Die Erfindung betrifft eine Schaltungsanordnung zur Entstörung einer Phasenanschnittsteuerung eines wechselstromgespeisten Verbrauchers mit einem in Reihe mit dem Verbraucher liegenden, in beiden Stromrichtungen über einen Steuerkreis ansteuerbaren Schalter und einer Entstördrossel sowie einem parallel zum Schalter liegenden Entstörkondensator. Circuit arrangement for interference suppression of a phase control of an AC-powered consumer The invention relates to a circuit arrangement for interference suppression of a phase control of an AC powered consumer with one lying in series with the consumer, in both directions of the current a control circuit controllable switch and an interference suppression choke and one in parallel to the switch lying interference suppression capacitor.
Bei einer bekannten derartigen Schaltungsanordnung sind Entstörkondensator und Entstördrossel als Tiefpaß dem Schalter für den Verbraucher vorausgeschaltet. Nachteilig hierbei ist, daß über die Drosselwicklungen der gesamte Verbraucherstrom floß. Hierdurch war eine verhältnismäßig große Drossel mit viel Eisen notwendig, und es trat eine verhältnismäßig große Wärmeentwicklung auf.In a known circuit arrangement of this type, interference suppression capacitors are used and interference suppression choke connected upstream of the switch for the consumer as a low-pass filter. The disadvantage here is that the entire consumer current is passed through the inductor windings raft. This required a relatively large choke with a lot of iron, and a relatively large amount of heat developed.
Der Erfindung liegt die Aufgabe zugrunde, eine Schaltungsanordnung zur Entstörung einer Phasenanschnittsteuerung der eingangs beschriebenen Art zu schaffen, bei der die Entstörungselemente billiger und gewichtsmäßig leichter sind und die Wärmeentwicklung verringert wird. Zudem soll der notwendige Haum für die Schaltungsanordnung verkleinert werden, so daß sie in kleineren Sinbaugeräten untergebracht werden kann.The invention is based on the object of a circuit arrangement for interference suppression of a phase control of the type described above create in which the interference suppression elements are cheaper and lighter in weight and the generation of heat is reduced. In addition, the necessary haum for the Circuitry can be reduced in size so that it can be accommodated in smaller built-in devices can be.
Die Erfindung löst diese Aufgabe dadurch, daß dem Schalter für den Verbraucher eine Reihenschaltung von einer Entstördrossel, einem in beiden Dtromrichtungen von einem Steuerkreis ansteuerbaren Hilfsschalter und einem Strombegrenzungswiderstand parallel geschaltet ist und daß der schalter für den Verbraucher je Halbwelle gegenüber dem Hilfsschalter zeitlich nacheilend durchschaltet.The invention solves this problem in that the switch for the Consumers a series connection of an interference suppression choke, one in both directions Auxiliary switch controllable by a control circuit and a current limiting resistor is connected in parallel and that the switch for the consumer per half-wave opposite the auxiliary switch is switched through with a time lag.
Uber die Enstördrossel fließt hierdurch nicht mehr der Hauptstrom für den Verbraucher, sondern nurmehr ein Verhältnismäßig kleiner liilfsstrom. hierdurch kann die Entstördrossel raummäßig kleiner und billiger gebaut werden.As a result, the main current no longer flows via the interference choke for the consumer, but only a relatively small auxiliary flow. through this the interference suppression choke can be built smaller and cheaper in terms of space.
Da außerdem wesentlich weniger eisen für die Drossel verwendet wird, ist die Wärmeentwicklung erheblich reduziert.Since much less iron is used for the throttle, the heat development is significantly reduced.
Um die Ansteuerkreise fur den behalter für den Verbraucher und für den tiilfsschalter besonders einfach zu gestalten, ist nach einer Ausgestaltung der Erfindung der Steuerkreis für den Hilfsschalter dem Phasenanschnitt entsprechend verstellbar, während der Steuerkreis für den Verbraucherschalter einen fest eingestellten Zeitverzögerungskreis besitzt, der vom Hilfsschalterkreis gespeist wird. Hierdurch wird mit einfachsten Mitteln erreicht, daß der Schalter für den Verbraucher unabhängig von dem eingestellten Phasenwinkel der Ihasenanschnittsteuerung des hilfsschalters gegenüber dem iiilfsschalter mit einer gleichbleibenden Sacheilzeit durchgeschaltet wird.To the control circuits for the container for the consumer and for Making the auxiliary switch particularly simple is, according to one embodiment the invention of the control circuit for the auxiliary switch corresponding to the phase control adjustable, while the control circuit for the consumer switch has a fixed setting Has a time delay circuit that is fed by the auxiliary switch circuit. Through this is achieved with the simplest means that the switch is independent for the consumer from the set phase angle of the phase angle control of the auxiliary switch switched through to the auxiliary switch with a constant advance time will.
Vorzugsweise ist der oteuerkreis für den behalter für den Verbraucher ein RC-Glied, das parallel zu dem Strombegrenzungswiderstand des Hilfsschalterkreises geschaltet ist, und der sondensator des RC-Gliedes ist an die Steuerelektrode und an einen Schaltereingang angeschlossen.The tax group is preferably for the container for the consumer an RC element that runs parallel to the current limiting resistor of the auxiliary switch circuit is connected, and the probe of the RC element is connected to the control electrode and connected to a switch input.
Vorzugsweise werden als schalter Triac oder Thyristoren in sntiparallelschaltung verwendet.Triac or thyristors in snti-parallel connection are preferably used as switches used.
bin Ausführungsbeispiel der Erfindung wird anhand eines in der Zeichnung dargestellten ochaltschemas näher erläutert.bin embodiment of the invention is based on one in the drawing illustrated circuit diagram explained in more detail.
Kn die Netzphasen Ph und bp ist der Verbraucher V, z.B.Kn is the network phases Ph and bp, the consumer V, e.g.
Glühlampe oder dergleichen,in reihe mit dem Schalter bv, z.B.Incandescent lamp or the like, in series with switch bv, e.g.
einem Triac, angeschlossen, parallel zum behalter bv liegt eine Reihenschaltung aus Entstördrossel D, Hilfsschalter z.B. einem Triac, und ein Dtrombegrenzungswiderstand R1.a triac, connected, parallel to the behalter bv is a series circuit from interference suppression choke D, auxiliary switch, e.g. a triac, and a current limiting resistor R1.
Der Schalter SH wird in üblicher Weise mit Phasenanschnitt gesteuert. Hierzu ist sein Gitter Sg an eine Triggerdiode TD angeschlossen, welche über ein RC-Glied angesteuert wird.The switch SH is controlled in the usual way with phase control. For this purpose, his grid Sg is connected to a trigger diode TD, which has a RC element is controlled.
Dieses wird gebildet aus dem kondensator C1 und den parallel geschalteten Widerständen R3, , R4, wobei der Widerstand R3 ein lotentiometer und 24 ein abgleichwiderstand ist.This is formed from the capacitor C1 and the parallel-connected Resistors R3,, R4, where the resistor R3 is a lotentiometer and 24 is a balancing resistor is.
1st der kondensator C1 auf die Zündspannung für die Triggerdiode TD aufgeladen, zündet diese durch. Damit wird auch der Hilfsschalter SH durchgeschaltet. Das RC-Glied C1, R3, R4 wird durch eine Rechteckspannung in positiver und negativer richtung gespeist. hierzu ist parallel zum Hilfsschalter ein Spannungsteiler angeschlossen, der von einem Widerstand 25 und einem spannungsabhängigen Widerstand VDR gebildet wird.If the capacitor C1 is set to the ignition voltage for the trigger diode TD charged, ignites this. This also switches the auxiliary switch SH through. The RC element C1, R3, R4 is made positive and negative by a square wave voltage direction fed. a voltage divider is connected in parallel to the auxiliary switch, formed by a resistor 25 and a voltage-dependent resistor VDR will.
Der btrom über den Hilfsschalter SH wird durch den Widerstand und den Verbrauchen V begrenzt. ar kann verhältnismäßig klein gehalten werden. Daner kann ein verhältnismäßig leistungsschwacher Hilfsschalter SH und eine kleine Drossel D verwendet werden.The btrom via the auxiliary switch SH is determined by the resistor and the consumption V is limited. ar can be kept relatively small. Daner a relatively inefficient auxiliary switch SH and a small choke can be used D can be used.
nnt der llilfsschalter SH durchgeschaltet, fällt am Widerstand eine Spannung ab, die den hondensator C2 über den Widerstand auflädt. Hat der Kondensator C2 die Zündspannung für den Hilfsschalter erreicht, schaltet auch der schalter bV durch, und der Verbraucher V wird mit dem Vollaststrom gespeist.If the auxiliary switch SH is switched through, a will drop across the resistor Voltage that charges the capacitor C2 through the resistor. Has the capacitor C2 reaches the ignition voltage for the auxiliary switch, switch bV also switches through, and the consumer V is fed with the full load current.
daß der Schalter SV durchgeschaltet, wird der Strom über die Drossel D, den Hilfsschalter SH und den Widerstand R1 praktisch zu null.that the switch SV is switched through, the current through the choke D, the auxiliary switch SH and the resistor R1 practically zero.
parallel zum Schalter SV ist noch ein Entstörkondensator C3 geschaltet, der zusätzlich bedämpfende punktion hat.An interference suppression capacitor C3 is connected in parallel to switch SV, who also has a dampening puncture.
bber den Hilfsschalter SH fließt somit bereits vor dem Durchschalten des Schalters SV ein Hilfsstrom, der wesentlich zur Verflachung der sonst steilen Einschaltspannungsanstieges am Verbraucher beiträgt und damit eine wesentliche Entstörung der Gesamtschaltung herbeiführt. Anstatt für die Schalter Triacs einzusetzen, ist es auch möglich, hierfür ihyristoren in intiparallelschaltung zu verwenden.The auxiliary switch SH therefore already flows before switching through of the switch SV an auxiliary current, which is essential to flatten the otherwise steep The switch-on voltage increase at the consumer contributes and thus a significant interference suppression the overall circuit brings about. Instead of using triacs for the switches, it is also possible to use thyristors in intiparallel connection for this purpose.
