Title:
CONVERSION CIRCUIT AND INDUCTOR
Document Type and Number:
WIPO Patent Application WO/2021/077312
Kind Code:
A1
Abstract:
A conversion circuit (100) and an inductor (103), applied to achieve high conversion efficiency of the inductor (103) in a full-load range. The conversion circuit (100) comprises a first charging/discharging circuit (101), a second charging/discharging circuit (102), an inductor (103), and a capacitor (104); the inductor (103) comprises a first input pin (1031), a second input pin (1032), and an output pin (1033), the output pin (1033) is coupled to the capacitor (104), the fist input pin (1031) is coupled to the fist charging/discharging circuit (101) or an input power supply, and the second input pin (1032) is coupled to the second charging/discharging circuit (102); an inductance parameter between the first input pin (1031) and the output pin (1033) is different from an inductance parameter between the second input pin (1032) and the output pin (1033).
