| 摘要 |
This power supply device, which generates a supply power to be outputted to an inverter and multiple external supply destinations, is provided with a first power supply transformer having a first primary winding and multiple first secondary windings wound outside of the first primary winding, and a second power supply transformer having a second primary winding electrically connected to one first secondary winding and multiple second secondary windings wound outside of the second primary winding. The multiple second secondary windings are connected to multiple external supply destinations, and among the multiple first secondary windings, the upper gate windings connected to an upper gate power supply circuit which turns ON and OFF a switching element on the upper arm of the inverter are wound at the outermost side so as to be spaced away from the aforementioned one first secondary winding. |
