High efficiency DC/DC converter with high conversion ratio
First Claim
1. A DC/DC converter comprising:
- a power switch for selectively switching an electrical connection between one side of a power supply and anodes of a first diode and a second diode;
a first capacitive element whose one side is connected to a cathode of the first diode;
a second capacitive element whose one side is connected to a cathode of the second diode;
a first-first switch for selectively switching an electrical connection between the other side of the first capacitive element and the other side of the power supply; and
a second-first switch for selectively switching an electrical connection between the other side of the first capacitive element and one side of the second capacitive element,wherein the first-first switch is turned on while the second first switch is turned off, and the first-first switch is turned off while the second-first switch is turned on.

Abstract
A high efficiency DC/DC converter with high conversion ratio is provided. The DC/DC converter includes a power switch for selectively switching an electrical connection between one side of a power supply and anodes of a first diode and a second diode, a first capacitive element whose one side is connected to a cathode of the first diode, a second capacitive element whose one side is connected to a cathode of the second diode, a first-first switch for selectively switching an electrical connection between the other side of the first capacitive element and the other side of the power supply, and a second-first switch for selectively switching an electrical connection between the other side of the first capacitive element and one side of the second capacitive element.
