摘要： 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.

摘要： 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.
