Title:
CAPACITOR AND POWER CONVERSION DEVICE
Document Type and Number:
Japanese Patent JP2023136977
Kind Code:
A
Abstract:
To reduce the number of components in a power conversion device that requires a ferrite core to reduce manufacturing costs and improve ease of assembly.SOLUTION: A capacitor 1 includes a hollow circular capacitor body 10. A hollow circular ferrite core 3 is provided in a hollow portion 14 of the capacitor body 10 coaxially with the capacitor body 10. The capacitor body 10 includes terminal portions 13P and 13N for P and N poles connected to a semiconductor module 4. The terminal portions 13P and 13N are exposed from the surface of the capacitor body 10 near the hollow portion 14 and protrude toward the axis of the capacitor body 10.SELECTED DRAWING: Figure 1
