一种基于三有源桥的多端口直流电力电子变压器

This article deals with a modular input-independent output-series (IIOS) multiport dc power electronic transformer (MDCPET). The IIOS structure allows for the connection of multiple dc units, such as photovoltaic (PV) arrays, storage devices, and dc loads, directly to the medium-voltage dc (MVdc) bus. This topology offers splendid galvanic isolation and less power conversion stages between dc unit...
