Abstract
A driving circuit controls driving of a switching element by outputting a driving signal to the switching element. The driving circuit includes an air-core transformer having a plurality of primary windings and a secondary winding magnetically coupled to each of the plurality of primary windings. An AC signal is input to each of the plurality of primary windings of the air-core transformer. The plurality of primary windings includes a first primary winding and a second primary winding. There is a phase difference between an AC signal input to the first primary winding and an AC signal input the second primary winding.
