Abstract: An electric power conversion apparatus includes a main DC-to-DC converter and an electric power conversion unit. The main DC-to-DC converter is configured to perform voltage conversion between a first-voltage section that operates at a first voltage and a second-voltage section that operates at a second voltage. The electric power conversion unit is connected with the first-voltage section and includes an electric power conversion section and an auxiliary DC-to-DC converter. The electric power conversion section is configured to perform electric power conversion between the first-voltage section and a third-voltage section that operates at a third voltage. The auxiliary DC-to-DC converter is connected in parallel with the main DC-to-DC converter. The auxiliary DC-to-DC converter shares a common configuration section with the electric power conversion section. The common configuration section is constituted of at least part of the electric power conversion section.

Abstract: An electric power source device has a transformer, primary side semiconductor components, secondary side semiconductor components, a choke coil, a base plate and first circuit substrate and one or more second circuit substrates. The transformer has a primary side coil and a secondary side coil. The primary side semiconductor components form a primary side circuit connected to the primary side coil. The secondary side semiconductor components form a secondary side circuit connected to the secondary side coil. The choke coil has a smoothing circuit for smoothing an output voltage. The transformer, the primary side semiconductor components, the secondary side semiconductor components and the choke coil are formed on the base plate. The first circuit substrate is arranged parallel to the base plate. The second circuit substrate is arranged parallel to a normal line of the first circuit substrate.

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.

Abstract: A power-supply apparatus is provided which includes a transformer, a primary semiconductor unit, a secondary semiconductor unit, and a secondary electronic device. Each of the primary semiconductor unit and the secondary semiconductor units has a plurality of semiconductor devices installed therein. The transformer, the primary semiconductor unit, the secondary semiconductor unit, and the secondary electronic device are electrically joined through connecting conductors. The transformer is laid on the primary semiconductor unit to make a first stack. Similarly, the secondary electronic device is laid on the secondary semiconductor unit. This permits the power-supply apparatus to be reduced in overall size thereof and minimizes adverse effects of electromagnetic noise to ensure the high efficiency in power supply operation.
