Dr. Yinchao Liu | Power Electronics | Research Excellence Award

Zhejiang University, China

Dr. Yinchao Liu is a Ph.D. researcher in the College of Electrical Engineering at Zhejiang University, Hangzhou, China, with research focused on wireless power transfer (WPT in power electronics). He has made notable contributions to series–series (SS) compensated WPT systems through both control strategies and parameter design methodologies. He proposed a monotonic and continuous frequency control method that enables seamless operation across constant-current and constant-voltage charging modes, even under large coil misalignment conditions. This method guarantees frequency monotonicity, maintains inverter zero-voltage switching (ZVS), and keeps the CC-mode operating frequency close to resonance, thereby ensuring high efficiency over wide coupling coefficient ranges. A graphical feasibility analysis was introduced to clearly illustrate the continuous frequency trajectory, followed by a systematic design framework and hardware implementation. Experimental results from 3.3 kW and 2.4 kW prototypes with coupling coefficients ranging from 0.1 to 0.3 validated the robustness and effectiveness of the approach. In addition, he developed a comprehensive multi-objective parameter design methodology for SS-compensated WPT systems that simultaneously satisfies rated output voltage requirements and ZVS operation while explicitly accounting for compensating capacitance tolerances and coupling coefficient variations, providing strong theoretical support for reliable and manufacturable high-power WPT system design.
