Abstract
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.
