Sun began his professional career in 1984,
designing aircraft electrical systems at the research and development
center of the Xian Aircraft Company in Xian, China. Beginning in
1991, he spent five years at the Institute for Power Electronics
and Electrical Devices at the University of Paderborn, in Paderborn,
Germany. He served as a research assistant, then as a research associate,
while pursuing a doctoral degree. Following completion of his degree,
Sun was a post-doctoral fellow at the Georgia Institute of Technology's
School of Electrical and Computer Engineering from 1996 to 1997.
He then worked at the Advanced Technology Center at Rockwell Collins
in Cedar Rapids, IA, as a senior engineer from 1997 to 1999. Sun
was promoted to principal engineer in 2000, and became a member
of the Rensselaer faculty in 2002.
Sun's primary research areas include power
electronics and electric energy conversion. More specifically, he
is studying high-frequency electric power conversion, including
dc-dc, ac-dc with power factor correction, and dc-ac; high-frequency
magnetic components and integration; power electronic circuits and
systems modeling, analysis, and control; power management for mobile
and portable devices; and power electronics applications in computers,
communications, aerospace, and energy systems.
