Patent ID: 7602156

Claim:
A boost converter, comprising: a first boost conversion unit, comprising: a first coil, having a first end coupled to a first voltage level; a first switch component, coupled between a second end of the first coil and a second voltage level, for selectively connecting the second end of the first coil to the second voltage level; a second switch component, wherein the first switch component and the second switch component are not turned on simultaneously; and a capacitor, having a first end coupled to the second switch component and a second end coupled to the second voltage level, wherein the second switch component is coupled between the second end of the first coil and the first end of the capacitor for selectively connecting the second end of the first coil to the first end of the capacitor; and a second boost conversion unit, comprising: a second coil, having a first end coupled to the first voltage level; a third switch component, coupled between a second end of the second coil and the second voltage level, for selectively connecting the second end of the second coil to the second voltage level; and a fourth switch component, coupled between the second end of the second coil and the first end of the capacitor, for selectively connecting the second end of the second coil to the first end of the capacitor, wherein the third switch component and the fourth switch component are not turned on simultaneously; wherein the first coil and the second coil are coupled to each other, and when the first switch component is turned on, the fourth switch component is turned on simultaneously, and when the third switch component is turned on, the second switch component is turned on simultaneously.
