Description
Die vorliegende Erfindung betrifft einen Leistungshalbleiter-Modul aus einer Vielzahl von parallel zueinander geschalteten IGBT-Chips, die jeweils eine Emitter-Leiterbahn, eine Basis-Leiterbahn und eine Kollektor-Leiterbahn wenigstens teilweise gemeinsam miteinander haben, wobei in mindestens eine der Leiterbahnen ein Schlitz eingebracht ist.The The present invention relates to a power semiconductor module of a plurality of parallel IGBT chips, each one Emitter trace, a base trace and a collector trace at least partially in common with each other have, wherein introduced into at least one of the conductor tracks a slot is.
In leistungselektronischen Modulen wird häufig eine Parallelschaltung einer Vielzahl von Bauelementen, wie beispielsweise IGBTs (IGBT = Bipolartransistor mit isoliertem Gate) vorgenommen, um so die Stromtragfähigkeit der Module insgesamt zu erhöhen. Beispielsweise kann die Nennstrombelastbarkeit von IGBT-Hochstrommodulen durch solche Parallelschaltung einer Vielzahl von IGBTs auf weit über 1000 A angehoben werden.In power electronic modules often becomes a parallel connection a variety of devices, such as IGBTs (IGBT = Bipolar transistor with insulated gate), so the ampacity to increase the total number of modules. For example, the rated current carrying capacity of IGBT high current modules by such a parallel connection of a plurality of IGBTs to well over 1000 A raised.
Bei IGBTs wird bekanntlich der Kollektorstrom von einem einen MOS-Kanal steuernden Gatespannungssignal beeinflusst, was es ermöglicht, einen Laststrom nicht nur einzuschalten, sondern diesen auch abzuschalten. Bei derartigen Vorgängen entstehen aber Schaltflanken, bei denen insbesondere beim Abschalten die Stromänderung -di/dt extrem hohe Werte im Bereich von 10 kA/μs annehmen kann.at IGBTs are known to be the collector current from a MOS channel controlling gate voltage signal influences what makes it possible not only turn on a load current, but also turn it off. In such operations arise but switching edges, where in particular when switching off the current change -di / dt can assume extremely high values in the range of 10 kA / μs.
Versuche
haben gezeigt, dass bei der Parallelschaltung von IGBTs während des
Abschaltvorganges hochfrequente Schwingungen auftreten können. Eine
besondere Art dieser Schwingungen ist beispielsweise in
Besonders störend sind bei der Parallelschaltung einer Vielzahl von IGBTs aber Schwingungen, die während des Abschaltvorganges selbst am Ende des sogenannten Miller-Plateaus auftreten können. Das Miller-Plateau bildet sich bekanntlich bei allen Abschaltvorgängen im Verlauf der Gate-Emitterspannung VGE in Abhängigkeit von der Zeit t aus. Es entsteht durch die Rückkopplung der Kollektorspannung über die Kollektor-Gate-Kapazität CCG auf das Gate.Especially disturbing are in the parallel connection of a plurality of IGBTs but vibrations, the while the shutdown itself at the end of the so-called Miller plateau may occur. The Miller Plateau is known to be at all shutdowns in the History of the gate-emitter voltage VGE as a function of time t off. It is created by the feedback the collector voltage over the collector gate capacitance CCG the gate.
Eingehende
Untersuchungen der Erfinder an einer Vielzahl von Leistungshalbleiter-Modulen
der in
Es hat sich gezeigt, dass der entscheidende Mechanismus für die Ausbildung der Plateau-Schwingungen in der Rückkopplung des Kollektorpotentials VCE über die Kollektor-Gate-Kapazität CCG auf die Gatespannung VGE besteht. Der langsame Anstieg des Kollektorpotentials VCE während des Miller-Plateaus bewirkt über diese Rückkopplung einen positiven Verschiebungsstrom auf das Gate des IGBTs, der zunächst stabilisierend wirkt und zur Ausbildung der konstanten Spannung während des Miller-Plateaus führt. Die für die Stärke der Rückkopplung maßgebliche Kollektor-Gate-Kapazität CCG ist dabei allerdings vom Stromfluss durch die einzelnen IGBT-Chips abhängig, da sie sich aus der Summe einer Oxid-Kapazität und einer stromabhängigen Sperrschichtkapazität zusammensetzt: je höher der Stromfluss ist, desto größer wird die Kollektor-Gate-Kapazität CCG, aufgrund der sich verengenden Raumladungszone, die die Sperrschichtkapazität bildet. Ein erhöhter Stromfluss führt so zur Zunahme des positiven Verschiebungsstromes und damit zur Aufsteuerung des Gates des betroffenen IGBTs. Hier aus resultiert ein Mitkopplungseffekt, der in einer Parallelschaltung von mehreren IGBT-Chips Schwingungen erzeugen kann. Um diesen Mechanismus zu ermöglichen, ist es also erforderlich, dass der konstante Gesamtlaststrom des Moduls sich inhomogen auf parallel geschaltete IGBT-Chips verteilen und während der Oszillation zumindest partiell von einem IGBT-Chip zum anderen IGBT-Chip kommutieren kann.It has been found that the decisive mechanism for the formation of the plateau oscillations consists in the feedback of the collector potential VCE via the collector-gate capacitance CCG to the gate voltage VGE. The slow rise of the collector potential VCE during the Miller plateau causes via this feedback a positive displacement current to the gate of the IGBT, which initially acts as a stabilizer and leads to the formation of the constant voltage during the Miller plateau. The for the strength of the return However, CCG is dependent on the current flow through the individual IGBT chips, since it is composed of the sum of an oxide capacitance and a current-dependent junction capacitance: the higher the current flow, the larger the collector gate becomes CCG capacity, due to the narrowing space charge zone that forms the junction capacitance. An increased current flow thus leads to an increase of the positive displacement current and thus to the control of the gate of the affected IGBT. This results in a positive feedback effect, which can generate vibrations in a parallel connection of several IGBT chips. Thus, to enable this mechanism, it is necessary for the constant total load current of the module to be inhomogeneous with parallel IGBT chips and at least partially commutated from one IGBT chip to the other IGBT chip during oscillation.
Die obigen theoretischen Überlegungen werden durch die folgende experimentell gewonnene Erkenntnis gestützt: Wenn unterschiedlich gestaltete Varianten von IGBT-Chips direkt miteinander verglichen werden, so tritt eine Neigung zu Plateau-Schwingungen bei Vorhandensein einer großen Kollektor-Gate-Kapazität CCG auf. Dies ist beispielsweise dann der Fall, wenn ein großer Zellabstand zwischen den einzelnen IGBTs vorliegt oder bei einem konstanten Zellabstand die Kanallänge der IGBTs reduziert wird. Beide Maßnahmen führen nämlich zu der Ausbildung einer relativ großen n–-leitenden Zone unterhalb des Gateoxids, welche für die Bildung der Kollektor-Gate-Kapazität CCG maßgeblich ist.The above theoretical considerations are supported by the following experimentally obtained finding: When differently designed variants of IGBT chips are directly compared with each other, there is a tendency for plateau oscillations in the presence of a large collector gate capacitance CCG. This is the case, for example, when there is a large cell spacing between the individual IGBTs or the channel length of the IGBTs is reduced at a constant cell spacing. Namely, both measures lead to the formation of a relatively large n - -conducting zone below the gate oxide, which is decisive for the formation of the collector-gate capacitance CCG.

Ausgehend von einem derartigen Stand der Technik ist es nun Aufgabe der vorliegenden Erfindung, einen Leistungshalblei ter-Modul aus einer Vielzahl von parallel zueinander geschalteten IGBT-Chips zu schaffen, bei dem ein partielles Hin- und Herkommutieren des Laststromes zwischen parallel-geschalteten IGBT-Chips vermieden wird, um so den Mechanismus der Mitkopplung zu unterdrücken, eine Gefährdung einzelner IGBT-Chips wegen Überbelastung zu vermeiden und EMV-Verträglichkeit des Moduls zu gewährleisten.outgoing From such a prior art, it is now the object of the present Invention, a Leistungshalblei ter module of a variety of parallel to each other to create IGBT chips, in which a partial back and forth commutation of the load current between parallel-connected IGBT chips is avoided, so the mechanism to suppress the positive feedback, one endangering individual IGBT chips due to overload to avoid and EMC compatibility of the module.
Diese Aufgabe wird bei einem Leistungshalbleiter-Modul der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass der Schlitz verzweigt ist.These Task is in a power semiconductor module of the aforementioned Type according to the invention thereby solved, that the slot is branched.
Die Erfindung ermöglicht so eine überraschend einfache Lösung der eingangs erläuterten Probleme: durch eine ohne weiteres zu realisierende Designregel für die Auslegung der Leiterbahnen von Emitter und/oder Basis und/oder Kollektor auf dem Substrat können Plateau-Schwingungen am Ende des Miller-Plateaus beim Abschalten des Moduls zuverlässig verhindert werden, ohne sonstige weitere Änderungen an dem Modul vornehmen zu müssen, die unter Umständen andere Nachteile nach sich ziehen könnten.The Invention allows such a surprise simple solution the problems explained at the outset: by a design rule that can be readily implemented for the design the tracks of emitter and / or base and / or collector on the substrate can Plateau vibrations at the end of the Miller plateau when the module is switched off reliable be prevented without making any other changes to the module to have that in certain circumstances could cause other disadvantages.

Selbst-verständlich sind auch Kombinationen der einzelnen Maßnahmen miteinander, also Schlitze in der Kollektor-Leiterbahn und der Emitter-Leiterbahn möglich. Gegebenenfalls können auch Schlitze in der Basis-Leiterbahn vorgesehen werden.The stray inductances be technically simple by introducing the branched Slots generated in the affected tracks.
