SCR’s AND TRIACS IN AUTOMOTIVE APPLICATIONS

INTRODUCTION
In power electronics the choice of the switch to be used is always very important for the designer: cost,
reliability, ruggedness and easiness to be driven must be permanently kept in mind. This is specially im-
portant in automotive where the designer has to optimize the numerous switching devices implemented
for a wide field of applications: ignition circuits, various electric motor controls, actuators in security sys-
tems, etc...
In the large family of electronic switches, the thyristor must be considered as a low cost and powerful de-
vice for many func
