Introduction to Power MOSFETs and Their Applications
INTRODUCTION
The high voltage power MOSFETs that are available today
are N-channel, enhancement-mode, double diffused, Metal-
Oxide-Silicon, Field Effect Transistors. They perform the
same function as NPN, bipolar junction transistors except
the former are voltage controlled in contrast to the current
controlled bi-polar devices. Today MOSFETs owe their
ever-increasing popularity to their high input impedance and
to the fact that being a majority carrier device, they do not
suffer from minority carrier storage time effects, thermal runaway,
or second breakdown. |
