具有高过载能力的模块化换相变换器

This letter proposes a novel modular commutation converter with high-overload capability for high-voltage dc transmission. The combination of single-switching-device modules (SDMs) and high-switching SDMs exploits the soft-switching characteristics of the topology and the high surge-current capability of integrated gate-commutated thyristors, enabling the converter to achieve short-term high-overl...
