Abstract
In this paper, protection of modular multilevel converter with half-bridge cells against overcurrent faults, which cannot be cleared by the converter, is investigated. Converter design with cell redundancy and a coupled branch reactor is considered. Special consideration is given to a separation of protection and permanent bypass functionality. Critical overcurrent protection design aspects are shown and supported by experimental data. Impact of reactor inductance mismatch in the branches on overcurrent protection design is investigated. This work was carried out within the frame of European FP7 program and its support is gratefully acknowledged.
