Abstract
A power converter includes an inductor, first through fourth switches, and a control device. The first switch is coupled between a first end of the inductor and ground, the second switch is coupled between an input end and a second end of the inductor, the third switch is coupled between the first end of the inductor and a first output end, and the fourth switch is coupled between the second end of the inductor and a second output end. The control device charges the inductor by turning on the first and second switches. Based on output voltages of the first and second output ends, the control device determines whether the first and second output ends are to be charged or discharged. The second and third switches are turned on for charging the first output end, or the first and fourth switches are turned on for discharging the second output end.
