Chang Liu received his B.S. from the Harbin Institute of Technology, China, and his M.S. from Zhejiang University, China, in 2016 and 2021, respectively, both in electrical engineering. From 2016 to 2017, he worked as a test engineer at Huawei Technologies in Shenzhen, China. In 2018, he served as a research assistant at Zhejiang University. Since September 2021, he has been pursuing his Ph.D. in electrical engineering at McMaster University’s Automotive Resource Centre (MARC) under the supervision of Dr. Ali Emadi. His research interests include modulation and control of converters, power converter design, and converter security. 

Full Profile

Chang Liu was born in Zhengzhou, China, and showed an interest in engineering from an early age. When he enrolled at the Harbin Institute of Technology (HIT) in 2012, studying engineering felt like a natural choice.

In his sophomore year, he led a student team in the Electronic Design Competition hosted by the College of Electrical Engineering at HIT. They designed a rotating clock powered by a DC motor, microprocessor, and LEDs. In 2016, for his bachelor thesis under Prof. Chengjun Liu, Chang developed an angle measuring system based on an absolute inductosyn. He proposed a new type of winding structure, which was later applied in a company-sponsored project.

After graduating from HIT, Chang joined Huawei Technologies in Shenzhen, China, as a test engineer for new product introduction (NPI). Shortly after joining, he became a team leader, responsible for introducing a new product into manufacturing. Working with world-leading technologies deepened his drive for innovation and professional growth.

In 2018, Chang joined Prof. Yan Deng’s research group at Zhejiang University as a research assistant. He later began his master’s studies in power electronics at the same university. During this time, he participated in several major research projects, including one under the Key R&D Program of China and another with the State Grid Corporation of China (SGCC).

His master’s thesis focused on modulation and control techniques for an inverter with a dual DC port. He proposed a modified space vector modulation that mapped the power flow of the two DC ports into the phase and length of a virtual vector. He also built a 3-kW prototype to verify his concept experimentally. During his master’s studies, Chang authored or co-authored five papers and earned two patents. In 2021, he received his M.S. with the Outstanding Graduate Student Award.

Since 2021, Chang has been pursuing his Ph.D. at McMaster University, Canada, under the supervision of Dr. Ali Emadi. His research extends beyond inverter design and control to include power converter security. Outside of research, he enjoys basketball, table tennis, and flight simulation.
