der nicht-vorveröffentlichten
Im Zusammenhang mit Leistungshalbleiterschaltelementen müssen vorgegebene Anforderungen an Kriech- und Luftstrecken bei der Übertragung der Steuersignale erfüllt werden. Dies kann durch die Verwendung von nicht-standardisierten IrDA-Übertragern (IrDA = Infrared Data Association) oder nicht-standardisierten Optokopplern erreicht werden. Derartige nicht-standardisierte Bauelemente sind jedoch aufwendig und damit teuer.in the Connection with power semiconductor switching elements must be specified Requirements for creepage distances and clearances in the transmission of Control signals fulfilled become. This can be done by using non-standardized IrDA transformers (IrDA = Infrared Data Association) or non-standard optocouplers be achieved. Such non-standardized components are but consuming and therefore expensive.

Davon ausgehend ist es eine Aufgabe der Erfindung, eine elektrische Schaltung zu schaffen, die mit einem geringeren Aufwand die Anforderungen an Kriech- und Luftstrecken erfüllt.From that Starting it is an object of the invention, an electrical circuit to create the requirements with less effort met at creepage distances and clearances.
Die Erfindung löst diese Aufgabe durch eine elektrische Schaltung nach dem Anspruch 1.The Invention solves this object by an electrical circuit according to the claim 1.
Bei der elektrischen Schaltung zur Ansteuerung eines Leistungshalbleiterschaltelements ist ein Steuersignal vorhanden, das zur Ansteuerung des Leistungshalbleiterschaltelements vorgesehen ist. Erfindungsgemäß sind zwei in Serie geschaltete Optokoppler vorgesehen, denen eingangsseitig das Steuersignal zugeführt ist, und die ausgangsseitig ein Signal abgeben, das im wesentlichen dem Steuersignal entspricht.at the electrical circuit for driving a power semiconductor switching element a control signal is present, which is used to drive the power semiconductor switching element is provided. According to the invention are two provided in series optocouplers whose input side supplied the control signal is, and the output a signal that essentially corresponds to the control signal.
Durch die Serienschaltung der beiden Optokoppler werden auch deren Luftstrecken hintereinandergeschaltet. Die gesamte Luftstrecke wird damit verdoppelt. Auf diese Weise ist es ohne einen größeren Aufwand möglich, vorgegebene Anforderungen an Kriech- und Luftstrecken bei der Übertragung der Steuersignale für ein Leistungshalbleiterschaltelement zu erfüllen.By the series connection of the two optocouplers will also their air gaps connected in series. The entire air gap is thus doubled. In this way, it is possible without a major effort, given Requirements for creepage distances and clearances during transmission the control signals for to meet a power semiconductor switching element.
Durch die galvanisch getrennte Spannungsversorgung für den Transistor des ersten Optokopplers und die Diode des zweiten Optokopplers werden entsprechende Anforderungen an Kriech- und Luftstrecken erfüllt.By the galvanically isolated power supply for the transistor of the first Optocoupler and the diode of the second optocoupler are corresponding Requirements for creepage distances and clearances fulfilled.
Dabei können vorzugsweise standardisierte Optokoppler verwendet werden, so dass der Aufwand und insbesondere die Kosten weiter reduziert werden.there can preferably standardized optocouplers are used, so that the effort and in particular the costs are further reduced.
Besonders vorteilhaft ist es, dass die erfindungsgemäße Schaltung modulartig in Serie schaltbar ist. Damit ist es möglich, die Schaltung beliebig zu erweitern und damit die entstehende Kriech- und Luftstrecke beliebig zu verlängern.Especially It is advantageous that the circuit according to the invention in a modular manner Series is switchable. This makes it possible to arbitrarily assign the circuit expand and thus the resulting creepage and clearance arbitrarily to extend.
Bei einer vorteilhaften Weiterbildung der Erfindung weist die Spannungsversorgung für die beiden Optokoppler einen induktiven Übertrager auf. Damit können die entsprechenden Anforderungen hinsichtlich einer galvanischen Trennung erfüllt werden.at an advantageous embodiment of the invention, the power supply for the two optocouplers on an inductive transformer. So that can corresponding requirements with regard to galvanic isolation Fulfills become.
