| Abstract |
In this paper the problem of overvoltages protection in high power IGBT inverters for
traction applications is presented. The turn off operation of the voltage clamped IGBT inverters described. The capability of the clamp circuit in limiting the IGBT turn-off voltage spikes is analyzed and the importance of the clamp diode electrical characteristics are pointed out. Finally, experimental and simulated results allow a direct comparison between standard ultrafast clamp
diodes and optimized clamp diodes. |
