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
