Title:
POWER CONVERTER AND CIRCUIT BOARD
Document Type and Number:
Japanese Patent JP2020205714
Kind Code:
A
Abstract:
To provide a power converter, and a circuit board constituting the power converter having a structure in which electronic components and magnetic components arranged so as to have different thicknesses or height positions can be mounted on a single substrate without complicated substrate shape, and both electronic components and magnetic components can contact a heat dissipation plate.SOLUTION: A power converter 100 includes circuit boards 10A and 10B, a magnetic component 24, a conductive member 23, heat dissipation plates 40A and 40B, a heat dissipation terminal block 50, and a housing 30. The magnetic component includes a core 24E and a coil pattern 25. The conductive member includes a coil pattern to which a core is attached. The circuit boards 10A and 10B are connected in a heat conductive manner on a main surface 40C of the heat dissipation plate. The heat dissipation terminal block fixes the circuit board and the conductive member so as to face each other at a distance from each other. The housing is in contact with a cooler in a heat conductive manner, and houses the conductive member and the heat dissipation plate. A part of the core is connected in a heat conductive manner to the main surface of the heat dissipation plate.SELECTED DRAWING: Figure 3
