Description
Die Erfindung betrifft eine Vorrichtung zur induktiven Übertragung elektrischer Energie mit einem Primärkreis und einem Sekundärkreis, der über einen Gleichrichter mit dem Pluspol und dem Minuspol eines durch die elektrische Energie zu ladenden Energiespeichers verbunden ist, wobei der Gleichrichter ein mit steuerbaren Schaltmitteln gebildeter Vollbrückengleichrichter ist, wobei die steuerbaren Schaltmittel Transistoren mit Substratdioden sind und wobei die Steueranschlüsse der steuerbaren Schaltmittel mit einer Steuerschaltung verbunden sind.The invention relates to a device for the inductive transmission of electrical energy with a primary circuit and a secondary circuit, which is connected via a rectifier to the positive pole and the negative pole of an energy store to be charged by the electrical energy, the rectifier being a full-bridge rectifier formed with controllable switching means, wherein the controllable switching means are transistors with substrate diodes, and the control connections of the controllable switching means are connected to a control circuit.
Eine Vorrichtung zur induktiven Übertragung elektrischer Energie mit einem Primärkreis und einem Sekundärkreis, der über einen Gleichrichter mit dem Pluspol und dem Minuspol eines durch die elektrische Energie zu ladenden Energiespeichers verbunden ist, ist aus der
Die
Aufgrund der den Schaltmitteln parallelgeschalteten (Substrat-) Dioden in den genannten Gleichrichtern kann jederzeit ein gleichgerichteter Strom fließen, wenn von der Primärseite Energie geliefert wird und der Energietransfer zum Energiespeicher nicht aktiv durch die Steuerschaltung verhindert wird. Ein Unterbrechen dieses Energietransfers erfolgt dabei in der Regel durch zusätzliche oder schon vorhandene Schalter im Gleichrichter.Due to the (substrate) diodes connected in parallel to the switching means in the mentioned rectifiers, a rectified current can flow at any time if energy is supplied from the primary side and the energy transfer to the energy store is not actively prevented by the control circuit. This energy transfer is usually interrupted by additional or existing switches in the rectifier.
Die verwendeten Gleichrichterschaltungen haben das Problem, dass auch ohne eine Versorgungsspannung der Gleichrichterelektronik, wie beispielsweise bei einem Abfall der Batteriespannung während des Ladevorgangs, ohne die Kontrolle der Steuerschaltung weiterhin Leistung aufgenommen werden kann. Eine aktive Ladeunterbrechung kann wegen des Ausfalls der Steuerschaltung nicht mehr erfolgen.The rectifier circuits used have the problem that even without a supply voltage for the rectifier electronics, for example in the event of a drop in the battery voltage during the charging process, power can continue to be consumed without the control of the control circuit. An active interruption in charging can no longer take place due to the failure of the control circuit.
Es ist daher die Aufgabe der Erfindung, auch bei einem Ausfall der Steuerschaltung eine Deaktivierung des Gleichrichters zu ermöglichen.It is therefore the object of the invention to enable the rectifier to be deactivated even if the control circuit fails.
Die Aufgabe wird durch eine Vorrichtung gemäß Anspruch 1 gelöst. Eine vorteilhafte Weiterbildung ist im Unteranspruch angegeben.The object is achieved by a device according to claim 1. An advantageous further development is specified in the dependent claim.
Demnach sind bei einer Vorrichtung zur induktiven Übertragung elektrischer Energie mit einem Primärkreis und einem Sekundärkreis, der über einen Gleichrichter mit dem Pluspol und dem Minuspol eines durch die elektrische Energie zu ladenden Energiespeichers verbunden ist, wobei der Gleichrichter ein mit steuerbaren Schaltmitteln gebildeter Vollbrückengleichrichter ist, wobei die steuerbaren Schaltmittel Transistoren mit Substratdioden sind und wobei die Steueranschlüsse der steuerbaren Schaltmittel mit einer Steuerschaltung verbunden sind, die Steueranschlüsse der mit dem Minuspol des Energiespeichers verbundenen Schaltmittel mit einer passiven Sperrvorrichtung verbunden, die mit dem Pluspol des Energiespeichers verbunden ist und die ausgebildet ist, die mit dem Minuspol des Energiespeichers verbundenen Schaltmittel im Falle eines Ausfalls der Steuerschaltung in den leitenden Zustand zu versetzen.Accordingly, in a device for inductive transmission of electrical energy with a primary circuit and a secondary circuit, which is connected via a rectifier to the positive pole and the negative pole of an energy store to be charged by the electrical energy, the rectifier being a full-bridge rectifier formed with controllable switching means, wherein the controllable switching means are transistors with substrate diodes and wherein the control connections of the controllable switching means are connected to a control circuit, the control connections of the switching means connected to the negative pole of the energy store are connected to a passive blocking device which is connected to the positive pole of the energy store and which is designed that to put switching means connected to the negative pole of the energy store in the conductive state in the event of failure of the control circuit.
Hierdurch ist es möglich, auch ohne die Steuerschaltung einen Ladestrom über den Gleichrichter zu verhindern.This makes it possible to prevent a charging current via the rectifier even without the control circuit.
Wenn über den Primärkreis Energie übertragen wird, setzt im Sekundärkreis sowie durch den Gleichrichter, der jetzt passiv und ohne Steuerung arbeitet, ein Stromfluss ein. Der Stromfluss bewirkt einen Spannungsaufbau an der positiven Seite des Gleichrichters, welcher im gleichen Moment zur Steuerung der Schalter über die passive Sperrvorrichtung verwendet wird. Durch das Ansteuern der Schalter mit einer hierdurch erzeugten Hilfsspannung der passiven Sperrvorrichtung wird der Gleichrichter gesperrt, wodurch ein Energietransfer unterbunden wird. Der Gleichrichter kann nur mit vorhandener Versorgungsspannung der Steuerschaltung und aktivem Abschalten der Hilfsspannung aktiviert werden. Es wird also eine Lösung mit einer passiven Sperrvorrichtung vorgeschlagen, die ausgebildet ist, den Gleichrichter zu verriegeln, ohne dass eine Versorgungsspannung der Steuerschaltung vonnöten ist. Um den Ladevorgang zu gewährleisten, muss zu jeder Zeit der Gleichrichter aktiv offengehalten werden können. Fällt die Versorgungspannung ab oder kann der Gleichrichter durch einen anderen Fehlerfall nicht offengehalten werden, sperrt dieser sofort.When energy is transmitted via the primary circuit, a current flow begins in the secondary circuit and through the rectifier, which now works passively and without control. The current flow causes a voltage build-up on the positive side of the rectifier, which is used at the same time to control the switches via the passive blocking device. By activating the switch with an auxiliary voltage of the passive blocking device generated thereby, the rectifier is blocked, whereby an energy transfer is prevented. The rectifier can only be activated when the supply voltage of the control circuit is available and the auxiliary voltage is actively switched off. A solution is therefore proposed with a passive locking device which is designed to lock the rectifier without the need for a supply voltage for the control circuit. To ensure the charging process, the rectifier must be able to be actively kept open at all times. If the supply voltage drops or the rectifier cannot be kept open due to another fault, it locks immediately.
In einer vorteilhaften Ausbildung der erfindungsgemäßen Vorrichtung ist die passive Sperrvorrichtung mit der Serienschaltung aus einem Pull-Up-Widerstand und einer Zenerdiode gebildet, die zwischen dem Plus- und dem Minuspol des Energiespeichers verschaltet ist, wobei die Steueranschlüsse der mit dem Minuspol des Energiespeichers verbundenen Schaltmittel mit dem Verbindungspunkt des Pull-Up-Widerstands und der Zenerdiode verbunden sind.In an advantageous embodiment of the device according to the invention, the passive blocking device with the series circuit is formed from a pull-up resistor and a Zener diode is connected between the positive and the negative pole of the energy store, the control connections of the switching means connected to the negative pole of the energy store being connected to the connection point of the pull-up resistor and the Zener diode.
Hierdurch werden die mit dem Minuspol des Energiespeichers verbundenen Schaltmittel geschlossen, so dass der Sekundärkreis über deren Durchlasswiderstände quasi kurzgeschlossen ist, sobald die Spannung am Ausgang des Gleichrichters, also am Pluspol des Energiespeichers die Schaltspannung des Schaltmittels überschreitet.This closes the switching means connected to the negative pole of the energy store, so that the secondary circuit is virtually short-circuited via its forward resistances as soon as the voltage at the output of the rectifier, i.e. at the positive pole of the energy store, exceeds the switching voltage of the switching means.

Several secondary circuit coils and several secondary circuit capacitors can also be provided.
Im Idealfall befinden sich sowohl der Primärkreis PK als auch der Sekundärkreis SK für die Frequenz der Wechselspannung der Wechselspannungsquelle UP in Resonanz, sodass möglichst viel Energie vom Primärkreis PK zum Sekundärkreis SK übertragen werden kann.In the ideal case, both the primary circuit PK and the secondary circuit SK are in resonance for the frequency of the alternating voltage of the alternating voltage source U P , so that as much energy as possible can be transferred from the primary circuit PK to the secondary circuit SK.
