摘要： A power switching device includes a power terminal connected to a power supply; a load terminal connected to a load; a power switch connected between said power terminal and said load terminal and arranged to be conductive in a first operating state; a power conductor connected between said power terminal and said load terminal in at least one state, wherein an electrical current through said power conductor changes in response to said power switch being turned off, thereby causing self-induction in said power conductor; and a control unit arranged to control said power switch in real-time on the basis of a real-time level of said voltage across said power conductor so as to turn off said power switch in a continuous or stepwise or pulsed manner to prevent a voltage across said power conductor from exceeding a maximum allowed level.

摘要： A semiconductor device may include first, second, and third semiconductor layers. The first and third layers may have a first dopant type, and the second layer may have a second dopant type. A first region within the third semiconductor layer may have the second dopant type. A second region between the first region and the second semiconductor layer may have the first dopant type. A third region above the second region may have the first dopant type. A fourth semiconductor region adjacent to the third region may have a first concentration of the second dopant type. A source contact region may have a second concentration of the second dopant type adjacent to the third semiconductor region and adjacent to the fourth semiconductor region. The second concentration may be higher than the first concentration.

摘要： A power switching device connected or connectable between a power supply and a load is described. The device may have at least two different operating states, each operating state having a different level of said output voltage associated with it. The power switching device may comprise: a power terminal connected or connectable to said power supply; a load terminal connected or connectable to said load, for providing said output voltage; a power switch connected between said power terminal and said load terminal and arranged to be conductive in a first one of said operating states; a power conductor connected between said power terminal and said load terminal in at least one of said states, wherein an electrical current through said power conductor changes in response to said power switch being turned off, thereby causing self-induction in said power conductor; and a control unit arranged to control said power switch in real-time on the basis of a real-time level of said voltage across said power conductor so as to turn off said power switch in a continuous or stepwise or pulsed manner to prevent a voltage across said power conductor from exceeding a maximum allowed level. A three-phase bridge inverter and a method of operating a power switching device are also described.
