description	This disclosure proposes procedures and systems for discharging system capacitors and de-energizing power transmission systems having Modular Multilevel Converter (MMC) topologies by intelligent control of MMC cell components including configuration of bypass and insert switches using integrated DC choppers to effectively de-energize MMC cell capacitors and/or DC-link capacitors under operating conditions such as after a normal stop, for protection against over-voltages, dumping turbine energy, and under certain hardware fault conditions. La présente invention concerne des procédures et des systèmes pour décharger des condensateurs de système et des systèmes de transmission de puissance hors tension ayant des topologies de convertisseur multiniveau modulaire (MMC) par commande intelligente de composants de cellules MMC comprenant la configuration de commutateurs de dérivation et d'insert à l'aide de découpeurs CC intégrés pour désactiver efficacement des condensateurs de cellules MMC et/ou des condensateurs de liaison CC dans des conditions de fonctionnement telles qu'après un arrêt normal, pour la protection contre les surtensions, la décharge d'énergie de turbine, et dans certaines conditions de défaut de matériel.
