A current going through the first power semiconductor is sensed by a first and a second current derivative sensing means, the current going through the second semiconductor is sensed by a third and a fourth current derivative sensing means, when the current going through the first power semiconductor increases, the first current derivative means providing a positive voltage and the second current derivative means providing an opposite negative voltage, when the current going through the second power semiconductor increases, the third current derivative means providing a positive voltage and the fourth current derivative means providing an opposite voltage and the system reduces the voltage on the gate of the first power semiconductor if the first and third current derivative means provide voltages of same sign and reduces the voltage on the gate of the second power semiconductor if the second and fourth current derivative means provide voltages of same sign.

Power module and method for manufacturing power module

The present invention concerns a device and a method for controlling the switching from a conducting state to a non conducting state or from a non conducting state to a conducting state of a semiconductor power switch providing current to a load, the device receiving an input signal that is intended to drive the semiconductor power switch. The invention: &#x2014;senses the derivative of the drain to source current going through the semiconductor power switch in order to obtain a voltage representative of the sensed derivative of drain to source current, &#x2014;amplifies the voltage representative of the sensed derivative of drain to source current, &#x2014;adds the amplified voltage representative of the derivative of the sensed drain to source current to the input signal during a given time period.
