TRANSFORMATION CONTROL DEVICE AND SOLENOID VALVE DRIVING DEVICE

There is provided a transformation control device of a transformation chopper circuit that transforms an input by turning on and off a current using a switch and outputs the transformed input. The transformation control device controls at least an ON/OFF state of a main switch by acquiring an output voltage of the transformation chopper circuit in a case where the main switch is in an ON state, the main switch being turned on in a case where energy is accumulated in an inductor.
