Abstract: A power supply unit includes: a transformer; a primary component that constitutes a primary circuit connected to the transformer; a secondary component that constitutes a secondary circuit connected to the transformer; a choke coil; a base plate including the transformer, the primary component, the secondary component and the choke coil; a metal plate connected to the base plate; and a connecting member connecting the primary component and the transformer. The primary component and the transformer are laminated to constitute a first laminating body. A part of the metal plate is disposed closer to the transformer than the primary component, and the metal plate and the transformer are electrically connected by a ground line. A connection point between the ground line and the metal plate is located closer to the transformer than the primary component.

Abstract: An electric power source device has a transformer, a primary-side semiconductor module, a secondary-side semiconductor module, a secondary-side electrical component, a base plate and a circuit substrate on which substrate-side electrical components are mounted. The primary-side semiconductor module has a larger exterior size than the secondary-side electrical component. The primary-side semiconductor module and the secondary-side electrical component form a stacked section. In the stacked section, the secondary-side electrical component is stacked, in a vertical direction, i.e. a direction of a normal line of a mounting surface of the base plate, on the primary-side semiconductor module. The primary-side semiconductor module is directly mounted on the mounting surface. At least a part of the substrate-side electrical components is arranged inside of the primary-side semiconductor module in a horizontal direction, and inside of a second surface of the stacked section toward the mounting surface along the normal line.
