Title: Wenbo Sun and Direct Power AC/DC Conversion

Introduction

Wenbo Sun is an inventor based in Dongguan, China. His patent work includes a direct power AC/DC converter designed to convert grid power into DC output through a dual-branch architecture.

Latest Patents

Sun is associated with 1 patent: “Direct Power AC/DC Converter.” The apparatus uses two branches that operate alternately and independently. In the first branch, an active half-bridge (AHB) switching network receives AC grid power and supplies AC power through a series resonant impedance to a transformer’s primary winding. The transformer’s secondary winding connects through a synchronous rectification switching device to the DC output.

The second branch uses a diode bridge to convert the AC grid power into DC power, which is supplied to a second AHB switching network. That network connects through another series resonant impedance to a separate primary winding of the transformer. The design combines the two conversion paths within one apparatus.
