ABSTRACT:
Disclosed is a variable DC voltage device wherein one terminal of a DC power supply, a switch, a first coil of a transformer, a second coil mounted on a core of the transformer with the same polarities with those of the first coil, a diode for preventing a shortcircuiting of the DC power supply when the switch is closed and the other terminal of the DC power supply are connected in series in the order named; a load is interconnected between the junction between the first and second coils and the other terminal of the power supply; and a compensation circuit is provided for restoring to an initial state the flux variation caused when the switch is closed, whereby the load is controlled by the alternate opening and closing of the switch.
