The first and second emitters are connected to the
In a DC-DC converter, the alternating current generated in the secondary winding of the transformer is rectified by a rectifier and supplied to the load via a smoother by applying rectangular wave input signals with mutually opposite phases to the bases of the transistors. A first capacitor is connected between the collector of the first transistor and the base of the second transistor, and a second capacitor is connected between the collector of the second transistor and the base of the first transistor. DC-DC converter.
