Abstract :
In this paper, an active gate control method for high power IGBTs in wind power generation system is investigated. With this method, the turn off voltage of the high power IGBTs using Trench-/Field-Stop technology can be clamped at proper level. The implementation of the control strategies is also introduced, which has been used in the practical wind power generation system. It is based on the control of the gradient and the magnitude of the IGBTs turn-off voltage. Simulation and experimental results show that the turn off voltage and its gradient of the high power IGBTs can be controlled properly.
