Title:
複合平滑インダクタおよび平滑化回路
Document Type and Number:
Japanese Patent JP6533342
Kind Code:
B2
Abstract:
A composite smoothing inductor 10 that can respond to an increase in demands for downsizing, a shift of a driving frequency toward a high frequency, and the like has a coupling transformer 20, a first smoothing inductor 30, a second smoothing inductor 40 on a substrate 50 in a concentrated manner. Each of two input terminals 11A and 11B is connected to the coupling transformer 20. One output part of the coupling transformer 20 is connected to the first smoothing inductor 30, and another output part of the coupling transformer 20 is connected to the second smoothing inductor 40. The first smoothing inductor 30 and second smoothing inductor 40 are each connected to an output terminal 12. The mutual inductance of the coupling transformer 20 is higher than the self-conductance of the first smoothing inductor 30 and the self-conductance of the second smoothing inductor 40.
