Mr. Tianyu Liu is a skilled product designer at XJ Electric Co., LTD., Xu Chang, China, recognized for his innovative contributions to power electronics and control systems. His research focuses on optimizing dc-dc converters, with a particular emphasis on enhancing the performance and efficiency of resonant converter systems. In his publication titled “Optimizing triple phase-shift modulation for CLLLC resonant converters” in the Journal of Power Electronics, he addresses key challenges such as insufficient low-voltage gain range and the difficulty of achieving wide-range zero-voltage soft switching (ZVS) under traditional modulation schemes. His study proposes an optimized triple phase-shift modulation strategy that effectively analyzes the impact of three phase angles on voltage gain and resonant current RMS, enabling better control and reduced losses. The proposed method, verified through a 1 kW prototype using a multiple-harmonic impedance model, demonstrates superior efficiency and a significantly expanded gain range. Beyond academic research, Tianyu has also applied his expertise in practical engineering through industry projects such as the design of Vehicle-to-Grid (V2G) smart charging piles and rectifier control systems for electric vehicle charging stations, contributing to the advancement of modern power conversion and sustainable energy technologies.
