“…This can be achieved by designing bus bars with consideration of current coupling effects to minimize the stray parameters difference [6], [7], or by synchronizing IGBT switching signals to trigger IGBTs simultaneously [8], as well as adjusting the gate voltages and the gate resistances based on the thermal imbalance [9], [10]. However, these methods can be hardly applied in high power module construction, where a unique gate lead is connected to the several sections of the module [11].…”
