Abstract

Modular Multilevel Converters deliver small foot-prints and efficiencies above 99% in their half-bridge format, butonly deliver DC-fault blocking with full-bridge sub-modules, andwith an unacceptable penalty in efficiency. The Alternate ArmConverter (AAC) is a hybrid circuit topology using a mixture offull-bridge sub-modules and director switches which is capableof current control through DC faults while maintaining goodefficiency in normal operation. Recently a new operational modehas been proposed, which removes several drawbacks of thepreviously presented topology. Hardware results for the AACoperating in this new mode are demonstrated for the first timein scaled experimental tests. Results showing operation in steady-state as well as dynamic power ramps and fault scenarios,including successful ride through of a DC side fault are presented
