| Abstract |
A converter cell for a Modular Multilevel Converter (MMC) suitable for the Chain-Link Converter topology is presented. IGCT semiconductors are being used as the main switch technology thanks to features like inherent stable Short Circuit Failure Mode (SCFM) capability very low overall losses superior load cycling capabilitiesThe cell makes use of a single thyristor switch to protect the cell against catastrophic damages in all relevant failure modes. The same thyristor enables continued operation of the chain-link converter after a single cell level failure. A comparison of losses in a STACOM application between IGBT plastic modules and hermetically sealed RC-IGCT press pack devices is presented. |
