Application Number: JP,2022-208015
Category (FI): H02M3/28@Y,H05K7/20@B,H05K9/00@L
Stage: PROBLEM TO BE SOLVED: To downsize a power supply device while securing both heat radiation performance and shielding performance.SOLUTION: A power supply device includes: a first board B1 with a transformer T; a first shield plate H1 stacked on the first board B1 through a lower heat transfer member Sd having prescribed thickness; a second board B2 with one or more choke coils C1..., stacked on the first shield plate H1 through an intermediate heat transfer member Sm having prescribed thickness; and a second shield plate H2 stacked on the whole or a part of the choke coils C1... through an upper heat transfer member Su having prescribed thickness. Heat radiation openings Rsd for radiating at least heat generated by the transformer T are formed in the first shield plate H1, the lower heat transfer member Sd, the intermediate heat transfer member Sm, the second board B2 and the second shield plate H2, and the first shield plate H1 and the second shield plate H2 are connected to a ground part G1 of the first board B1 and a ground part G2 of the second board B2 through one or more conductive parts.SELECTED DRAWING: Figure 1 (Grant)
