Abstract: Air-cooledhuge-capacityconvertertypically hasa disadvantage in on-site layout, this paperdescribes the designofa distributedmethod, which can effectively avoid the problem with installation and layout, caused by the large size in the area, length and weight of air-cooledhuge-capacityconverter. And
