Abstract

The present invention concerns a device for controlling the switching of a first and a second power semiconductor switches providing current to a load in a half bridge configuration. The device comprises: - means for obtaining 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, - means for limiting the current through the second switch during the switching of the second switch from non-conducting to conducting state using the obtained first current value, by modifying the gate signal of the second switch, - means for obtaining 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, - means for limiting the current through the first switch during the switching of the first switch from non-conducting to conducting state using the obtained second current value by modifying the gate signal of the first switch.
