摘要： A method and an arrangement are provided for balancing the switching transient behavior of parallel connected power semiconductor components. The method includes providing a switch signal to the parallel connected power semiconductor components for changing the state of the components, forming control signals for each of the parallel connected components from the switch signal, and determining, during the change of state of the power semiconductor component, the voltage induced to an inductance in the main current path of the component in each of the parallel connected components. The method also includes comparing each of the induced voltages with a predetermined threshold voltage, measuring time differences between the time instants at which the induced voltages crosses the threshold voltage, and modifying one or more of the control signals on the basis of the measured time differences in the respective following state change for balancing the switching transient behavior.
