Abstract

10kV IGCT has been recently developed and has the potential to push wind turbine systems to higher power and voltage rating. Converters employing IGCTs need snubber and OVP circuit to limit the rate of current's rising and peak over voltage across IGCT during turn on and off state, respectively. The conventional RCD snubber which is used in such power converter dissipates a significant amount of power. In order to reduce the amount of energy lost by conventional RCD snubber, this paper proposes flyback-type snubber. Flyback type snubber not only meets all of the IGCTs characteristics during on and off-state but also significantly saves the power loss. Proposed flyback-type snubber can save up to 73% of the loss in conventional di/dt snubber circuit according to PLECS® magnetic simulation of 3-level NPC GSC. The experiments are performed using IGCT stack. Flyback transformer yields the effectiveness of proposed snubber in wind turbine systems.
