Title:
複合平滑インダクタおよび平滑化回路
Document Type and Number:
Japanese Patent JP7050456
Kind Code:
B2
Abstract:
To provide a composite smoothing inductor that can meet increasing demands for downsizing and higher driving frequency.SOLUTION: A coupling transformer 20 comprises a transformer core 24 having a through-hole penetrating in the first direction and made of a magnetic material. A first smoothing inductor 30 comprises a first core having a through-hole and made of a magnetic material. A second smoothing inductor 40 comprises a second core having a through-hole and made of a magnetic material, and a composite smoothing inductor 10 comprises a first coil C1 passing through the inside of the through-hole of the transformer core 24 and passing through the inside of the through-hole of the first core and a second coil C2 passing through the inside of the through-hole of the transformer core 24 while maintaining the insulation state and passing through the inside of the through-hole of the second core.SELECTED DRAWING: Figure 3
