Thanks for your time. I received the B.S., M.S. degrees in Electrical Engineering and Automation from Xi’an Jiaotong University (XJTU) and Huazhong University of Science and Technology (HUST), China, in 2009&2012 respectively, the Chinese top-ranked universities in Electrical Engineering field. During that time, I learned professional knowledge in EE major, gained solid base knowledge for further research.I think power electronics (PE) is a very promising and indispensable discipline and is crucial in solving energy problems. ● I have been working for nearly 12 years with sufficient industrial & first-hand experiences in PE field, including PE digital control algorithm, power stage hardware design, time-critical embedded software architecture design and development, time synchronization network development experiences, proficient in C programming language, VHDL, MATLAB and Python, which are all used in relevant projects.● I am proficient in classical control theory, modern control theory , modern power electronics which can be seen in my transcripts, also I learned nonlinear control theory, MPC algorithm based on optimal control theory. I am familiar with PE underlying hardware characteristics, just like switch, inverter nonlinearity characteristics, etc. All of these make me gain a deeper understanding in PE digital control. I am also very interested in applying intelligent control algorithm to PE field, such as reinforcement learning & deep learning, etc. ● I am proficient in MBD development process with C code automatic generation which is a very effective and rapid way for verifying control algorithm, proficient in DSP and SOC chip architecture, e.g. TI DSP Series (283X8/2837x/280049), SOC (Zynq2020/TI Jacinto/ AM243x), FPGA, Speedgoat&dSPACE RCP&HIL platform. ● I having global research and work experience, many expert around me come from Germany, Japan and the United States in Midea Group.● I am an energetic person with excellent learning ability. I enjoy hiking, long-distance race (Marathon results 3h15min), tennis. GRE score is 335(Q170+V165) +3.5. Meanwhile, I realized there are also insufficient theoretical knowledge to support me to do further research.
