Title:
POWER CONVERSION CIRCUIT, SEMICONDUCTOR DEVICE, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/241622
Kind Code:
A1
Abstract:
This power conversion circuit comprises: a first capacitor having one end connected to an input terminal and the other end connected to a reference potential; a second capacitor having one end connected to an output terminal and the other end connected to the reference potential; an inductor which has one end connected to the one end of the first capacitor, and the other end connected to the one end or the other end of the second capacitor, accumulates magnetic field energy by allowing at least a part of an input current and the current output from the first capacitor to flow as a first current, and induces, with the magnetic field energy, a second current that causes the second capacitor to store electric charges; and a switching element that turns on and off in a substantially constant cycle, wherein the turn-on period of time during one cycle is almost constant, the first current flows through the inductor when turned on, and the switching element turns off when the second current flows through the inductor.
