A Structured Approach to
Power Line EMI Filter Design
Daniel M. Mitchell
Rockwell International
Abstract: This tutorial presents detailed design
algorithms for proven EMI input filter configurations for
switching regulated power supplies. Lagrangian multipliers
are used to minimize input filter volume subject to the
constraints of (1) compliance with conducted emissions
requirements (using switching regulator noise models) and
(2) overall filter/regulator system stability/performance
goals (using small-signal models).

Passive Lossless Snubbers
for High Frequency PWM Converters
Sam Ben-Yaakov and Gregory Ivensky
Ben-Gurion University of Negev
Abstract: This tutorial covers the theoretical
aspects of passive lossless snubbers for switches and
diodes, covering both "classical" and new snubber
topologies. The main focus is on the practical aspects of
the design including resonant components and analysis of the
limitations that the snubbers impose. A specific design
example of a snubber for a 1 kW boost converter operating as
an active power factor front-end is discussed in detail and
experimental results are presented.

Advanced Single Stage
Power Factor Correction Techniques
Fred C. Lee and
Jinrong Qian
Virginia Power Electronics Center
Abstract: This tutorial will provide an overview
of single stage power factor correction techniques. The
integrated single stage PFC technique will be discussed. The
concept of charge pump PFC techniques, unity power factor
conditions for both voltage source and current source charge
pump PFC converters will be introduced and discussed. A
family of charge pump PFC topologies and experimental
results will be presented.
