Title:
MILLIMETER WAVE-BASED SWITCHING POWER SUPPLY
Document Type and Number:
WIPO Patent Application WO/2024/077920
Kind Code:
A1
Abstract:
Disclosed in the utility model is a millimeter wave-based switching power supply, comprising an input voltage circuit, an upper bridge LLC circuit and a lower bridge LLC circuit of a transformer primary winding, a millimeter wave switch control chip, and an output voltage circuit, wherein the upper bridge LLC circuit comprises a first capacitor C1, an inductor L1, and an input end and an output end of the millimeter wave switch control chip; and the lower bridge LLC circuit comprises a second capacitor C2, the inductor L1, and an output end and a grounding end of the millimeter wave switch control chip. A short-distance transmission mode with millimeter waves as carriers is adopted, wireless transmission and signal isolation can be realized by means of an antenna, an optocoupler and an additional isolation layer are not needed, and therefore it can be guaranteed that signal transmission has a high speed, a small time delay, and high efficiency, and is safer.
