Abstract
The modular multilevel converters (MMC) form the backbone of the modern voltage source converter (VSC) based HVDC system due to their unique features. Faults within the MMC affect the performance of the HVDC system. In this paper the fault types that can occur in the MMC are investigated. The reported work focuses on sub-module faults. A nine level MMC was simulated using PSCAD/EMTDC in this investigation.
