| description | Methods and systems for HVDC and/or MVDC power transmission and/or distribution, using circuit breakers where a series-connected stack of fully-bidirectional bipolar junction transistors is the initial interrupter in the current path. Preferably these transistors are operated with two pre-turnoff phases, to deplete minority carrier population and thus provide a faster transition to complete turnoff.
L'invention concerne des procédés et des systèmes pour la transmission et/ou la distribution de puissance HVDC et/ou MVDC, à l'aide de disjoncteurs dans lesquels un empilement connecté en série de transistors bipolaires à jonctions entièrement bidirectionnels est l'interrupteur initial dans le chemin de courant. De préférence, ces transistors fonctionnent avec deux phases avant mise hors tension, pour appauvrir la population de porteurs minoritaires et permettre ainsi une transition plus rapide vers la mise hors tension complète. |
