具有受控直流侧故障阻断能力的模块化多电平变换器

Fault current characteristics in dc systems depend largely on the response, and hence also the topology, of the ac-dc converters. The presently used ac-dc converter topologies may be categorized into those with controlled or uncontrolled fault-blocking capability and those lacking such capability. For topologies of the former category, generic models of the dc-side fault response have not yet been...
