Title:
A DC-TO-DC CONVERTOR
Document Type and Number:
WIPO Patent Application WO/2021/212322
Kind Code:
A1
Abstract:
The present disclosure provides a DC-DC convertor utilizing soft-switching controlling scheme. The convertor comprises a filter inductor and a transformer having a magnetic core assembly, a primary winding wound on the magnetic core assembly, and a secondary winding. The secondary winding winds on the magnetic core assembly at a distance from the primary winding, the distance making an amount of leakage inductance generated from the primary winding not less than inductance of a resonant inductor. Size of the convertor is reduced due to the integration of the magnetic components.
