Introduction
The technology in the area puter modeling and simulation is
growing at a rapid pace. puters e faster and more capable,
new software provides greater capability. This progress in technology is
of great benefit to design engineers and to panies that employ
them. This book is intended to show how to harness the capability of
computer modeling and the simulation of power circuits.
Why Simulate?
On more than one occasion, I have been asked (usually by my superi-
ors) why there always seems to be a quest for newer, puters
and software. Why are so many precious budget dollars requested for
conferences and training seminars? After giving this question a great
deal of thought, I have the following conclusions:
Simulation saves money. Design flaws that are not detected until
the production cycle may delay schedules and significantly increase
production costs. Simulation is an aid to the early detection of these
errors. Monte Carlo and worst-case simulations help to ensure max-
imum production yield. With the help of simulation, expensive parts
and systems can be effectively debugged without the possibility of
destroying them.
Simulation saves time. Circuits can be simulated on puter
much more quickly than they can be built and evaluated.
Simulation measures the immeasurable. Computer simulation al-
lows engineers to evaluate a circuit with the worst-case values or
difficult environmental conditions. It would be quite a challenge to
build a circuit that passes all worst-ponent values, or

tion allows these types of conditions to be easily evaluated.
Simulation promotes safety. Simulation a
