Device and method for controlling switching

Device for controlling the switching of a first and a second power semiconductor switches providing current to a load in a half bridge configuration, characterized in that the device comprises:

• first obtainer to obtain a first current value through the first switch or the load just before the switching of the first switch from conducting to non-conducting state,
• first limiter to limit the current through the second switch during the switching of the second switch from non-conducting to conducting state using a reference value derived from the obtained first current value, by modifying the gate signal of the second switch,
• second obtainer to obtain a second current value through the second switch or the load just before the switching of the second switch from conducting to non-conducting state,
• second limiter to limit the current through the first switch during the switching of the first switch from non-conducting to conducting state using another reference value derived from the obtained second current vain;
• by modifying the gate signal of the first switch.
