【应用笔记】汽车应用中可控硅 AN871 APPLICATION NOTE 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……
