Abstract
A bi-directional voltage converter having a first switch, a second switch, an inductor, a third switch, a fourth switch and a fifth switch connected in parallel with the third switch. The first switch is connected between an input terminal and a first switching terminal, the second switch is connected between the first switching terminal and a reference ground, the inductor is connected between the first switching terminal and an output switching terminal, the third switch is connected between the output switching terminal and a system terminal, the fourth switch is connected between the output switching terminal and the reference ground. When the bi-directional voltage converter is regulated to work in a buck charging mode or a boost discharging mode, the first and second switches are controlled to conduct on and off complementarily, the third and fifth switches are maintained at on state, the fourth switch is maintained at off state.
