Power converter

A power converter, coupled to an inductor, a first capacitor with a first terminal and a second terminal, and a second capacitor, comprising:

• a first switch and a second switch coupled in series and coupled between an input of the power converter and a reference voltage;
• a third switch and a fourth switch, wherein the third switch is coupled between the first terminal of the first capacitor and the fourth switch, the second terminal of the first capacitor is coupled to the reference voltage, the fourth switch is coupled between an output of the power converter and the third switch, a terminal of the second capacitor is coupled between the third switch and the fourth switch, and another terminal of the second capacitor is coupled between the first switch and the second switch through the inductor;
• a fifth switch coupled between the reference voltage and a first common node, wherein the first common node is located between of the inductor and the second capacitor;
• and
• a sixth switch coupled between the first common node and a second common node, wherein the second common node is located between the third switch and the first capacitor;
• wherein a third terminal of the inductor is coupled to the second capacitor and coupled to the first capacitor through the sixth switch, and a fourth terminal of the inductor is coupled between the first switch and the second switch;
• wherein the third terminal of the inductor is directly connected to the sixth switch and the fifth switch;
• in a first phase, the first switch, the third switch, and the fifth switch are turned on, and the second switch, the fourth switch, and the sixth switch are turned off.
