MODULAR MULTILEVEL CONVERTERS

A converter arm (50A) for a modular multilevel converter is described. The converter arm (50A) includes a plurality of series-connected submodules (521, 522,..., 52n). Each submodule includes a plurality of semiconductor devices, each semiconductor device including at least a controllable semiconduc...

description	A converter arm (50A) for a modular multilevel converter is described. The converter arm (50A) includes a plurality of series-connected submodules (521, 522,..., 52n). Each submodule includes a plurality of semiconductor devices, each semiconductor device including at least a controllable semiconductor switch (S1, S2, ..., S4), an energy storage device (C), and first and second alternating current AC terminals (54, 56). At least one of the plurality of submodules is an active submodule (522, ..., 52n) and at least one of the plurality of submodules is a redundant submodule (521). Each redundant submodule (521) further includes an inserting switch (58) connected between the respective first and second AC terminals (54, 56). The inserting switch (58) includes a fast-acting circuit breaker adapted to be opened in response to a detected fault in an active submodule and an optional contactor.
