Power supply circuit

A power supply circuit, comprising:

• a plurality of output terminals that output voltages;
• and
• a transformer that has a plurality of output windings, the output windings including first, second and third output windings that are coupled to each other, wherein
• each of the first through third output windings has a first terminal and a second terminal, each of the first terminals has a first polarity, and each of the second terminals has a second polarity opposite to the first polarity, and
• the first output winding has first and second center taps, each of the first and second center taps functioning as the first terminal,
• the first terminal of the second output winding is connected to the first center tap via a first capacitor so that a number of turns of the second output winding is equal to a number of turns between the second terminal and the first center tap of the first output winding,
• the first terminal of the third winding is connected to the second center tap via a second capacitor so that a number of turns of the third output winding is equal to a number of turns between the second terminal and the second center tap of the first output winding, and
• the second terminals of the first through third output windings are electrically connected to each other.
