Title:
VOLTAGE CONVERTER
Document Type and Number:
WIPO Patent Application WO/2023/233912
Kind Code:
A1
Abstract:
This voltage converter converts DC voltage between an input line and an output line. The voltage converter comprises: a variable inductor device disposed between the input line and the output line; a switching device disposed between the input line and the variable inductor device; a capacitor disposed between the output line and the ground line; and a control circuit. The control circuit performs, in accordance with load current that is the current flowing through the output line, switching of the inductance value of the variable inductor device and switching of the control mode of the switching device.
