Title:
MAGNETIC INTEGRATED CIRCUIT AND POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/028804
Kind Code:
A1
Abstract:
Provided in the embodiment of the present invention are a magnetic integrated circuit and a power conversion device. The magnetic integrated circuit comprises: a number N of magnetic devices spacedly arranged, N input windings, a first output loop, and a second output loop. The i-th magnetic device comprises: a magnetic center column; a narrow-side column; a wide-side column; a first magnet yoke and a second magnet yoke disposed at both ends of the narrow-side column; and a third magnetic yoke and a fourth magnetic yoke disposed at both ends of the wide-side column. The i-th magnetic device is any one of the N magnetic devices. The j-th input winding is disposed on the magnetic center column of the i-th magnetic device. The j-th input winding is any one of the N input windings, and the N input windings are connected in parallel. Both i and j are positive integers, and N is a positive integer greater than or equal to two. By implementing the embodiment of the present invention, output voltage can be increased without changing an input coil, and output coil loss can be reduced.
