Abstract：The RCD active gate control circuit for series connected IGBTs is researched in order to balance the IGBT’s collector-emitter voltage dynamically. The principle of the RCD active gate control circuit and parameters selection guide of the circuit elements is introduced. The function of each element is analyzed with the help of equivalent circuit under different switch states of IGBT, and the design method of RCD active gate control circuit is proposed to meet the voltage balancing requirement. The feasibility of the proposed method is verified by an experimental system, and the results show that voltage balancing is well achieved whether gate signal of IGBTs in a series stack is synchronous or not.
