MULTI-REFERENCE-LEVEL WIDE-RANGE GAIN ADJUSTMENT HIGH-TRANSFORMATION-RATIO DC/DC CONVERTER
Document Type and Number:
WIPO Patent Application WO/2023/206953
Kind Code:
A1
Abstract:
Disclosed in the present invention is a multi-reference-level wide-range gain adjustment high-transformation-ratio DC/DC converter, which consists of an N-stage high-transformation-ratio DC/DC converter and a reference level converter, or contains a high-frequency compensation circuit. The N-stage high-transformation-ratio DC/DC converter is used for realizing high-transformation-ratio voltage conversion, the reference level converter is an isolated converter or a non-isolated converter, and the output end thereof can output adjustable voltages having different polarities, or the converter is an independent external power supply. The positive and negative state and the size of the level value of the output end of the reference level converter influence the voltage transformation ratio of the N-stage high-transformation ratio DC/DC converter, and the fluctuation and the wide range change of the voltage of a power supply can be resisted by adjusting the level value. The high-frequency compensation circuit compensates the high-frequency power fluctuation. The present invention improves a traditional switching resonant converter, wide-range gain adjustment of the converter is realized while the voltage transformation ratio of the converter is improved, and the stability of the output voltage of a load side is ensured. If the high-frequency compensation circuit is added, the dynamic response speed can be increased.
