TRIAC analog control circuits for inductive loads
Introduction
The TRIACs of today are well suited to the requirements of switching inductive loads.
TRIAC control circuits must be particularly well tuned to be both economical and applicable
to inductive loads.
The purpose of this document is to present different methods of TRIAC control with their
applications and to analyze their relative advantages and disadvantages.
A simple circuit offering all the guarantees of reliability is proposed for inductive loads.
