具有电流平衡变压器功能的集成耦合电感用于两相同步DC-DC变换器

With the emerging technology of wide-band-gap power semiconductors and modern ferrite materials, the switching frequency of dc-dc converters can be pushed to mega-hertz range to achieve higher power density. In order to deal with a high conduction current, multiphase converters are adopted to distribute the current for both power devices and windings. However, the current unbalance among phases ma...
