Abstract
This chapter investigates the thermal stress of wind power converter when suffering grid faults. The comprehensive analysis for the electrical and thermal behaviors of power devices undergoing various grid faults is conducted on the 3L-NPC wind power converter. Afterwards, a series of thermal-redistributed modulation methods and a power control strategy which utilizes the zero sequence current are presented to achieve better performance under this adverse condition.
