Power supply apparatus

A power supply apparatus comprising:

• an inverter that includes a group of output terminals, generates alternating-current power from direct-current power, and outputs generated power from the group of output terminals;
• a first transformer that transforms alternating-current power output from the group of output terminals;
• a second transformer that is connected to the group of output terminals in parallel to the first transformer, arranged on an opposite side of the first transformer with respect to a straight line passing through a center of the group of output terminals and extending perpendicularly to a plane including the group of output terminals, and transforms alternating-current power output from the group of output terminals;
• a plurality of first conductive lines that connect the group of output terminals and both ends of the first transformer;
• and
• a plurality of second conductive lines that connect the group of output terminals and both ends of the second transformer, wherein
• an area of a first loop formed by the inverter, the first conductive lines, and the first transformer is equal to an area of a second loop formed by the inverter, the second conductive lines, and the second transformer.
