光伏发电系统中多端口级联DC/DC变换器的短路容错拓扑

A multiport dc/dc converter with cascaded submodules (SMs) can be employed in a photovoltaic (PV) power generation system for its high step-up ratio. Consisting of multiple low-voltage (LV) input ports and one high-voltage (HV) output port, the multiport converter is more likely to suffer short-circuit faults than a two-port converter. To ensure reliable operation of the converter, its short-circu...
