POWER SUPPLY APPARATUS
First Claim
1. A power supply apparatus comprising:
- a stack assembly comprising;
a transformer including a primary coil and a secondary coil; and
a first semiconductor device constituting a primary circuit connected to the primary coil of the transformer,one of the transformer and the first semiconductor device being stacked on the other thereof to constitute the stack assembly;
a second semiconductor device constituting a secondary circuit connected to the secondary coil of the transformer;
a choke coil connected to the second semiconductor device;
a base plate having a major surface, the stack assembly, the second semiconductor device, and the choke coil being located on the major surface;
a primary direct-current wire connecting the first semiconductor device to a direct-current power source and drawn out from a first predetermined portion of the stack assembly; and
a primary alternating-current wire connecting the first semiconductor device and the transformer and drawn out from a second predetermined portion of the stack assembly,the primary direct-current wire and the primary alternating-current wire being located to be separated from each other via at least a part of the stack assembly.

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.
