Abstract
A soft switching system DC-DC converter includes a switching element, a transformer or a reactor, and a controller configured to control a switching operation of the switching element; and carries out the switching operation of the switching element in a state that a voltage or a current to be applied to the switching element is zero. In a case where a required output value of the DC-DC converter is lower than the minimum output over which soft switching is established, the controller controls the operation of the switching element so that an operation period in which an output of the DC-DC converter becomes the minimum output or higher and a stop period in which the output becomes zero are alternately repeated.
