Title:
SWITCHING POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/171202
Kind Code:
A1
Abstract:
A circuit element 10a has parallelized resonance circuits. A resonance capacitor Crkq in a q-th one of the parallelized resonance circuits is connected at one end in series to a resonance reactor Lrq and a primary winding N1q of a transformer Trq. The resonance capacitor Crkq of the q-th one of the parallelized resonance circuits is connected at the other end to a resonance capacitor Crkq of a q-th one of parallelized resonance circuits in another circuit element 10a so as to configure, from a Pk-number of circuit elements, a k-dimensional multiphase LLC converter having a phase difference of 360°/Pk.
