适用于高压直流应用的新型混合级联DC-DC变换器

A dc-dc converter is essential for interconnecting HVdc networks of different voltage levels. This letter introduces a new family of dc-dc converters consisting of semiconductor switches and stack of submodules, which is named as hybrid-cascaded dc-dc converter (HCDC). This concept shows very attractive capital costs and low power losses. In this letter, the detailed operating principle of the HCD...
