The subject of power electronics is concerned with solid state devices for the
d
control and conversion of electrical power. These silicon devices are designed
u
for the transfer current from one part of an electrical circuit to another and the
c
synthesis of voltage and current waveforms. Power electronics has a wide range
t
of applications, from the small systems used in electrical appliances to the very i
o
large systems for the supply and distribution of electricity.
n

Containing useful concepts and the building blocks that go into making a t
o
power converter operate successfully, this book provides a description of the

characteristics of different types of power semiconductor devices and their P
application to power converter circuits. Applications to power transmission, o
electric drives, and medical equipment are also included to illustrate the wide
w
range of power electronics in both small- and high-power circuits.
