Patent ID: 11469681

Abstract:
A power supply device includes a first output unit that outputs a first alternating current, a second output unit that outputs a second alternating current, and a current combining unit that combines the first alternating current and the second alternating current. The current combining unit includes a first bus bar, a second bus bar, a first conductive member welded to a first surface of the first bus bar and connected to the first output unit, a second conductive member that is welded to a second surface of the first bus bar, penetrates the second bus bar, and is connected to the second output unit, a third conductive member welded to a first surface of the second bus bar and connected to the second output unit, and a fourth conductive member that is welded to a second surface of the second bus bar, penetrates the first bus bar, and is connected to the first output unit. The second surface of the first bus bar faces the second surface of the second bus bar.
