Abstract
(DE)
Die Erfindung betrifft eine Leistungsschalteranordnung (1) umfassend einen Low-Side- Transistor (LSS) und einen High-Side-Transistor (HSS),die so eingerichtet sind, dass sie in jeweils abwechselnden Zeitabschnitten einer Schaltperiode der Leistungsschalteranordnung (1) leitend geschaltet sind oder sperrend geschaltet sind. Ein Source-Anschluss (2) des Low-Side-Transistors (LSS) ist mit einem Lastanschluss (3) verbunden und ein Drain-Anschluss (5) des Low-Side-Transistors (LSS) ist über eine Speicherinduktivität mit einer Versorgungsspannung (Vin) verbunden.Ein Drain- Anschluss (6) des High-Side-Transistors (HSS) ist mit dem Lastanschluss (3) verbundenund ein Source-Anschluss (7) des High-Side-Transistors (HSS) istüber die Speicherinduktivität mit der Versorgungsspannung (Vin) verbunden. Erfindungsgemäß wird eine Leistungsschalteranordnung (1) der genannten Art bereitgestellt, dadurch gekennzeichnet, dass der Low-Side-Transistor (LSS) mindestens zwei Transistor- Segmente (LSS1, LSS2, LSS3) umfasst. Mindestens zwei der Transistor-Segmente weisen in der Verbindung zur Speicherinduktivität einen anderen elektrischen Widerstand (R1, R2, R3) auf. Die Leistungsschalteranordnung (1) ist so eingerichtet, dass mindestens zwei der Transistor-Segmente (LSS1, LSS2, LSS3) während eines Schaltvorgangs der Leistungsschalteranordnung (1) zu einem anderen Zeitpunkt geschaltet werden. Dadurch werden ungewollte Spannungsschwankungen reduziert, ohne dass die Schaltverluste deutlich ansteigen.

The invention relates to a power switch arrangement (1) comprising a low-side transistor (LSS) and a high-side transistor (HSS), which are designed such that the low-side transistor and the high-side transistor are conductingly switched or blockingly switched, each in alternating time periods of a switching period of the power switch arrangement (1). A source terminal (2) of the low-side transistor (LSS) is connected to a load terminal (3) and a drain terminal (5) of the low-side transistor (LSS) is connected to a supply voltage (Vin) via a storage inductance. A drain terminal (6) of the high-side transistor (HSS) is connected to the load terminal (3) and a source terminal (7) of the high-side transistor (HSS) is connected to the supply voltage (Vin) via the storage inductance. According to the invention, a power switch arrangement (1) of the aforementioned type is provided, characterized in that the low-side transistor (LSS) comprises at least two transistor segments (LSS1, LSS2, LSS3). At least two of the transistor segments have a different electrical resistance (R1, R2, R3) in their connection to the storage inductance. The power switch arrangement (1) is designed such that at least two of the transistor segments (LSS1, LSS2, LSS3) are switched at different times during a switching process of the power switch arrangement (1). This reduces unwanted voltage fluctuations without the switching losses significantly rising.

L'invention concerne un arrangement commutateur de puissance (1) comprenant un transistor côté bas (LSS) et un transistor côté haut (HSS), lesquels sont conçus de telle sorte qu'ils sont rendus passants ou rendus bloquants dans des portions de temps alternées respectives d'une période de commutation de l'arrangement commutateur de puissance (1). Une borne de source (2) du transistor côté bas (LSS) est reliée à une borne de charge (3) et une borne de drain (5) du transistor côté bas (LSS) est reliée à une tension d'alimentation (Vin) par le biais d'une inductance de stockage. Une borne de drain (6) du transistor côté haut (HSS) est reliée à la borne de charge (3) et une borne de source (7) du transistor côté haut (HSS) est reliée à la tension d'alimentation (Vin) par le biais de l'inductance de stockage. L'arrangement commutateur de puissance (1) selon l'invention est caractérisé en ce que le transistor côté bas (LSS) comprend au moins deux segments de transistor (LSS1, LSS2, LSS3). Au moins deux des segments de transistor présentent une résistance électrique différente (R1, R2, R3) dans la liaison vers l'inductance de stockage. L'arrangement commutateur de puissance (1) est configuré de telle sorte qu'au moins deux des segments de transistor (LSS1, LSS2, LSS3) sont commutés à un moment différent pendant une opération de commutation de l'arrangement commutateur de puissance (1). Cela permet de réduire les fluctuations de tension indésirables sans augmentation importante des pertes de commutation.
