resonant converters as a means of
substantially raising the operating
frequency of converters and thereby
decreasing their weight and size. He
performed early original analyses of
these converters, developed laboratory prototypes, and, working with
GE operating departments, trans-
ferred the technology to products.
Results of this research include a
lightweight, multiple-output dc-dc
resonant converter technology that
was first launched in commercial
communication satellites in the early
1990s (a three-to-one weight reduction compared with conventional
pulsewidth modulation designs), a
1,000-W resonant converter technology used in a U.S. Navy combat control system, high-power, high-voltage
X-ray generator technology that was
used in medical CT applications, and
high-power switching gradient amplifier technology used in GE's MRI
imagers. Through these developments, he has helped move the resonant technology from its infancy
through actual product applications.
The "fundamental approximation"
analysis techniques he developed for
describing resonant power converters
