Title: Yafeng Liao and Resonant Dual Active Bridge Conversion
Introduction
Yafeng Liao is an inventor based in Hangzhou, China, whose patent work concerns power conversion technology. He is associated with Hoymiles Power Electronics Inc. His listed portfolio includes 1 patent.
Latest Patents
Liao’s patent, “Control Method for Resonant Dual Active Bridge Conversion Circuit, Controller, and Converter,” describes a method for controlling a resonant dual active bridge conversion circuit. The method samples the primary- and secondary-side direct-current voltages and the secondary current, then calculates voltage gain from the input and output voltages. It uses the gain to determine intra-bridge phase shift and phase-angle difference values at the resonant frequency, calculates the switching frequency based on secondary current, and generates control signals for switches in both circuits.
Career Highlights
Liao’s listed invention addresses coordinated control of switching frequency and phase relationships in a resonant dual active bridge converter. This approach is intended to guide operation of the converter’s primary and secondary switches.
Collaborations
Liao is associated with Hoymiles Power Electronics Inc. His listed coworker is Bingwen Weng.
