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: In a power converter, an external terminal, a case, and capacitors are arranged to provide a conductive loop. The conductive loop defines thereinside a first region through which magnetic flux of an AC magnetic field penetrates, and a second region through which the magnetic flux penetrates. A magnetic-flux shielding member partly shields at least one of the first region and the second region from penetration of the magnetic flux of the AC magnetic field to adjust at least one of an amount of the magnetic flux penetrating through one of the first region and the second region, and an amount of the magnetic flux penetrating through the other thereof.

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.

Abstract: In a power supply apparatus, one of a transformer and a first semiconductor device is stacked on the other thereof to constitute a stack assembly. The stack assembly, a second semiconductor device, and a choke coil are located on the major surface. A primary direct-current wire, which connects the first semiconductor device to a direct-current power source, is drawn out from a first predetermined portion of the stack assembly. A primary alternating-current wire, which connects the first semiconductor device and the transformer, is drawn out from a second predetermined portion of the stack assembly. The primary direct-current wire and the primary alternating-current wire are located to be separated from each other via at least a part of the stack assembly.
