Mit der vorliegenden Lösung wird angestrebt, bei unverändertem Gehäuse die Spannungsbegrenzung bei Abschaltimpulsen sowie die Überspannungsfestigkeit zu verbessern.With the present solution is sought, with unchanged casing the voltage limit for switch-off pulses as well as the overvoltage resistance to improve.
Vorteile der ErfindungAdvantages of invention
Die erfindungsgemäße Entstörvorrichtung mit dem kennzeichnenden Merkmal des Anspruchs 1 hat den Vorteil, dass gegenüber einem Varistor durch eine geeignete Auswahl der Zenerspannung an der bidirektionalen Zenerdiodenstrecke eine recht genaue und damit den jeweiligen Anforderungen des Kraftfahrzeug-Herstellers entsprechende Spannungsbegrenzung von Abschaltimpulsen erzielt wird. Desweiteren wird durch die entsprechende Auswahl der Zenerspannung gegenüber einem Varistor auch die Überspannungsfestigkeit verbessert.The Entstörvorrichtung invention with The characterizing feature of claim 1 has the advantage that across from a varistor by a suitable selection of the zener voltage the bidirectional Zener diode path a pretty accurate and thus corresponding to the respective requirements of the motor vehicle manufacturer Voltage limitation of shutdown pulses is achieved. Furthermore is determined by the appropriate choice of zener voltage over one Varistor also the surge resistance improved.
Durch die in den Unteransprüchen aufgeführten Maßnahmen ergeben sich zweckmäßige Ausgestaltungen und Weiterbildungen des im Hauptanspruch angegebenen Merkmals.By in the subclaims listed activities arise expedient embodiments and further developments of the feature specified in the main claim.
So ist es zur Erzielung einer kostenoptimalen Lösung vorteilhaft, wenn die beiden Z-Diodenstrecken in einer bidirektionalen Zenerdiode vereinigt sind. Alternativ dazu ist es vorteilhaft, zum Beispiel wenn die gegeneinander geschalteten Z-Diodenstrecken unterschiedlich dimensioniert werden sollen, hierzu eine bidirektionale Z-Diode mit je nach Richtung unterschiedlichen Durchbruchspannungen oder zwei diskrete Z-Dioden zu verwenden, welche anodenseitig oder kathodenseitig miteinander verbunden sind und im Bedarfsfall unterschiedliche Durchbruchsspannungen aufweisen können. Die Z-Diodenstrecke mit der höheren Durchbruchsspannung ist dabei vom Minus- zum Pluspotential in Durchlassrichtung geschaltet.So it is advantageous to achieve a cost-optimal solution when the two Z-diode paths are combined in a bidirectional Zener diode. Alternatively, it is beneficial, for example if the against each other switched Z-diode sections are dimensioned differently to do this, a bidirectional Zener diode with depending on the direction different breakdown voltages or two discrete Zener diodes to use which anode side or cathode side with each other are connected and, if necessary, different breakdown voltages can have. The Z-diode path with the higher Breaking voltage is from the negative to the positive potential in the forward direction connected.
Da es sich hierbei um maximal drei Entstörelemente handelt, können diese auch in das bisherige kompakte Gehäuse mit seinen standardisierten Abmessungen eingesetzt und vergossen werden.There These are a maximum of three suppression elements, these can also in the previous compact housing with its standardized Dimensions are used and potted.
