Abstract (en)
[origin: US2020169252A1] A power-switch-system (PSS) having a low-side transistor (LSS) and a high-side transistor (HSS), which are switchable to be conductive or switched to be blocking in respectively alternating time-segments of a switching-period of the PSS. A source-terminal of the LSS is connected to a load-terminal, and a drain-terminal of the LSS is connected to a supply-voltage via a storage-inductor. A drain-terminal of the HSS is connected to the load-terminal, and a source-terminal of the HSS is connected to the supply-voltage via the storage-inductor. Provided is a PSS of this kind, the LSS having at least two transistor-segments. At least two of the transistor-segments have a different electrical resistance in the connection to the storage-inductor. The PSS provides that at least two of the transistor-segments are switched at a different point in time during a switching operation of the PSS to reduce unwanted voltage fluctuations, without markedly increasing switching losses.
