Mit der vorliegenden Erfindung wird eine Schaltung zur Ansteuerung von zwei oder mehreren elektrischen Verbrauchern geschaffen, die eine Empfängereinheit zur Einspeisung einer Wechselspannung in die Schaltung und jeweils parallel zu der Empfängereinheit angekoppelte Verbraucherpfade aufweist. Jeder Verbraucherpfad weist jeweils einen der Verbraucher und eine Ansteuerungseinheit auf. Durch Variation der Frequenz und/oder der Amplitude der eingespeisten Wechselspannung sind die Verbraucher selektiv über die Ansteuerungseinheiten ansteuerbar.With the present invention, a circuit for Control of two or more electrical Consumers created a receiver unit for Feeding an AC voltage into the circuit and each coupled in parallel to the receiver unit Has consumer paths. Every consumer path points one of the consumers and one control unit on. By varying the frequency and / or the amplitude of the AC voltage fed in are the consumers selectively controllable via the control units.

Vorzugsweise wird in mindestens einem der Verbraucherpfade die Ansteuerungseinheit in Serie zu dem jeweiligen Verbraucher geschaltet.Preferably in at least one of the consumer paths the control unit in series with the respective Consumers switched.
Besonders vorteilhaft erweist sich die erfindungsgemäße Ansteuerung für Verbraucher die eine im Wesentlichen ohmsche Charakteristik aufweisen. Bei frequenzabhängigen Verbrauchern muss der Frequenzverhalten entsprechend mit berücksichtigt werden. The invention has proven to be particularly advantageous Control for consumers the one essentially have ohmic characteristics.

Für die Empfängereinheit kann beispielsweise eine Luftspule und/oder eine Spule mit einem permeablen Kern verwendet werden.For example, an air coil can be used for the receiver unit and / or a coil with a permeable core is used become.
In einer derartigen Schaltung kann nun durch Einspeisung einer Wechselspannung in die Empfängereinheit ein selektives Ansteuern der Verbraucher über die Ansteuerungseinheiten durch Variation der Frequenz und/oder der Amplitude der eingespeisten Wechselspannung erfolgen.

Aus dem Vorangegangenen wird damit ersichtlich, dass ein Vorteil der erfindungsgemäßen Ansteuerung insbesondere in der Einfachheit, Robustheit und Kleinheit bei einer Ausführung der Schaltung liegt.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung.Further advantages, features and details of the invention emerge from the description below more preferred Exemplary embodiments and with reference to the drawing.
Fig. 1 zeigt eine stark miniaturisierbare Ansteuerung von zwei (im Wesentlichen) ohmschen Verbrauchern über eine induktive Schnittstelle. Generell handelt es sich bei dem vorliegenden System um eine implantierbare Ansteuereinheit für zwei oder mehr (ohmsche) Verbraucher, die auf kleinstem Bauraum realisierbar ist. Fig. 1 shows a highly miniaturizable controlling two (substantially) resistive loads via an inductive interface. In general, the present system is an implantable control unit for two or more (ohmic) consumers, which can be implemented in the smallest of spaces.
In eine Empfängerspule 10 kann durch eine (nicht gezeigte) extrakorporale Sendeeinheit eine Wechselspannung eingespeist werden. Jeweils parallel zu der Empfängerspule 10 sind zwei Verbraucherpfade 20A und 20B angeschlossen. Jeder Verbraucherpfad 20A und 20B weist dabei jeweils einen Verbraucher 30A und 30B, sowie eine Ansteuerungseinheit 40A und 40B auf.An AC voltage can be fed into a receiver coil 10 by means of an extracorporeal transmitter unit (not shown). Two consumer paths 20 A and 20 B are connected in parallel to the receiver coil 10 . Each consumer path 20 A and 20 B each has a consumer 30 A and 30 B, as well as a control unit 40 A and 40 B.
Durch Variation der Frequenz und/oder der Amplitude der eingespeisten Wechselspannung lassen sich über die Ansteuerungseinheiten 40A und 40B die Verbraucher 30A und 30B selektiv ansteuern.By varying the frequency and / or the amplitude of the AC voltage fed in, the consumers 30 A and 30 B can be selectively controlled via the control units 40 A and 40 B.
In dem in Fig. 1 dargestellten bevorzugten Ausführungsbeispiel werden die Ansteuerungseinheiten 40A und 40B durch selektive Filter für die jeweils eingespeiste Wechselspannung realisiert. Im einfachsten Fall können die Ansteuerungseinheiten 40A und 40B - wie in Fig. 1 beispielhaft dargestellt - ein Hochpassfilter und ein Tiefpassfilter sein.In the preferred exemplary embodiment shown in FIG. 1, the control units 40 A and 40 B are implemented by selective filters for the alternating voltage fed in in each case. In the simplest case, the control units 40 A and 40 B - as shown by way of example in FIG. 1 - can be a high-pass filter and a low-pass filter.
Im Betrieb der Schaltung nach Fig. 1 und bei in etwa gleich großen Verbrauchern 30A und 30B mit im Wesentlichen ohmscher Charakteristik wird bei hohen Frequenzen der in die Empfängerspule 10 eingespeisten Wechselspannung der Tiefpass 40A hochohmig und der Hochpass 40B niederohmig. Hierdurch fällt an dem (ohmschen) Verbraucher 30A eine geringere Leistung und an dem (ohmschen) Verbraucher 30B eine höhere Leistung ab. Entsprechend wird bei niedrigen Frequenzen der Tiefpass 40A niederohmig und der Hochpass 40B hochohmig, so dass an dem Verbraucher 30A eine höhere Leistung und an dem Verbraucher 30B nur eine geringere Leistung abfällt. Hierdurch wird ersichtlich, wie durch Wahl der Frequenz der in die Empfängerspule 10 eingespeisten Wechselspannung die Leistungsaufnahme in den Verbraucherpfaden 20A und 20B gesteuert werden kann.In operation, the circuit of FIG. 1 and at approximately the same size consumers 30 A and 30 B with a substantially resistive characteristic of fed into the receiver coil 10 AC voltage of the low-pass is 40 A high impedance at high frequencies and the high-pass filter 40 B low impedance. As a result, a lower power drops at the (ohmic) load 30 A and a higher power drops at the (ohmic) load 30 B. Correspondingly, at low frequencies, the low-pass filter 40 A becomes low-resistance and the high-pass filter 40 B becomes high-resistance, so that a higher output drops at the consumer 30 A and only a lower output at the consumer 30 B. This shows how the power consumption in the consumer paths 20 A and 20 B can be controlled by selecting the frequency of the AC voltage fed into the receiver coil 10 .
Es ist ohne weiteres ersichtlich, dass durch Variation der Amplitude der in die Empfängerspule 10 eingespeisten Wechselspannung entsprechend die Leistungsaufnahme in den Verbraucherpfaden 20A und 20B gesteuert werden kann.It is readily apparent that by varying the amplitude of the AC voltage fed into the receiver coil 10 , the power consumption in the consumer paths 20 A and 20 B can be controlled accordingly.
Anstelle der in Fig. 1 dargestellten Hoch- und Tiefpassfilter können die Ansteuerungseinheiten 40A und 40B auch durch beliebige andere frequenzselektive Filter, wie Bandpässe oder Bandsperren, ausgeführt werden.Instead of the high-pass and low-pass filters shown in FIG. 1, the control units 40 A and 40 B can also be implemented by any other frequency-selective filter, such as band-pass filters or band-stop filters.
Sollen zu den zwei Verbraucherpfaden 20A und 20B noch weitere Verbraucherpfade 20i (mit i = C, D, E, . . .) hinzutreten, so werden auch diese jeweils parallel zu der Empfängerspule 10 angeschlossen, wobei jeder Verbraucherpfad 20i dabei jeweils einen Verbraucher 30i und eine Ansteuerungseinheit 40i aufweist.If additional consumer paths 20 i (with i = C, D, E,...) Are to be added to the two consumer paths 20 A and 20 B, these are also connected in parallel to the receiver coil 10 , with each consumer path 20 i in each case has a consumer 30 i and a control unit 40 i.
Anstelle der reinen Serienschaltung von Verbraucher 30 und Ansteuerungseinheit 40 kann auch ebenso, bei geeigneter Wahl der Filterelemente, eine gemischte Serien- und Parallelschaltung der Ansteuerungseinheit 40 zu dem Verbraucher 30 treten. Instead of the pure series connection of consumer 30 and control unit 40 , a mixed series and parallel connection of the control unit 40 to the consumer 30 can also occur with a suitable choice of the filter elements.
Die Empfängerspule 10 kann insbesondere eine einfache Luftspule oder auch eine Spule mit einem permeablen Kern, wie z. B. Eisen oder Ferrit, sein.The receiver coil 10 can in particular a simple air coil or a coil with a permeable core, such as. B. iron or ferrite.
In einer bevorzugten Ausführungsform der vorliegenden Erfindung in dem eingangs angeführten Mikroaktuator sind die beiden Verbraucher 30 in Fig. 1 durch Formgedächtnis- Legierungsdrähte (FGLs) realisiert. Über die Ansteuerungseinheiten 40 lassen sich die FGLs nun selektiv durch eine in die induktive Schnittstelle der Empfängerspule 10 eingekoppelte Wechselspannung ansteuern.In a preferred embodiment of the present invention in the microactuator mentioned at the outset, the two consumers 30 in FIG. 1 are realized by shape memory alloy wires (SMA). Via the control units 40 , the SMA can now be selectively controlled by an AC voltage coupled into the inductive interface of the receiver coil 10 .
