Title:
COUPLING INDUCTOR AND SWITCHING CIRCUIT
Document Type and Number:
Japanese Patent JP2020047907
Kind Code:
A
Abstract:
To provide a multi-phase coupling inductor capable of achieving stable performance and size and cost reductions.SOLUTION: A coupling inductor 10 is used for a multi-phase switching circuit of interleave method. The coupling inductor 10 is configured to constitute an inductor unit 1 formed from a core 7 and a winding 8 wound around two positions of the core 7. Three inductor units 1 are arranged on an inductor installation surface and the two windings 8 wound around the common core 7 of the respective inductor units 1-3 are connected to each of different phases of the switching circuit.SELECTED DRAWING: Figure 3
