Abstract: A direct-current (DC) voltage conversion device includes an energy providing circuit, a first transistor switch, a second transistor switch, a third transistor switch, a fourth transistor switch, and an output capacitor. The first transistor switch is turned on. The second transistor switch and the fourth transistor switch are turned off.

When the third transistor switch is turned on, the parasitic capacitance discharges the output capacitor to establish the same voltage drops across the parasitic capacitance and the output capacitor. After establishing the same voltage drops across the parasitic capacitance and the output capacitor, the parasitic capacitance of the second transistor switch charges the parasitic capacitance of the fourth transistor switch, thereby establishing a zero voltage drop across the fourth transistor switch and achieving zero voltage switching.
