Title:
RESONANCE CONVERTER
Document Type and Number:
WIPO Patent Application WO/2023/219128
Kind Code:
A1
Abstract:
Provided are m-number of lower conversion circuits (10 1-m) constituting an LLC resonance converter in which operations are performed by turning on and off an upper switch element (QH) and a lower switch element (QL) together with a resonance inductor (Lr). Also provided are n-number of upper conversion circuits (10m+1-m+n) constituting the LLC resonance converter in which primary windings (T1) and resonance capacitors (Cr) are operated by turning on and off the upper switch element (QH) and the lower switch element (QL) together with the resonance inductor (Lr). Further provided are: a lower adjustment inductor (Lpd) connected in parallel to the primary windings (T1) of the m-number of lower conversion circuits (10 1-m); and an upper adjustment inductor (Lpu) connected in parallel to the primary windings (T1) of the n-number of upper conversion circuits (101-m).
