AN307使用可控硅对感性负载 AN307 APPLICATION NOTE USE OF TRIACS ON INDUCTIVE LOADS INTRODUCTION Although triac circuits are now well known by designers. The use of these components for inductive loads requires certain precautions which should not be neglected of optimum use is to be made of them. That is the purpose of this article which reviews the various triac control modes and recalls the principles which guarantee its correct operation. Phenomena Occurring when the Circuit is Closed The triac is known as a component which is essential in controlling power from an AC source (mains). In most cases, the circuit has an inductive componen……
