Application note

Inductive load control with AC switches

Introduction
AC switches are now commonly used as static switches to drive inductive loads such as
magnetic transformers, valves, induction motors, etc.
This application note describes the particular points to focus on when such loads are
controlled by AC switches like Triac, ACS or ACST. For example, there is an explanation of
just when a Triac has to be triggered to reduce the inrush current at turn on.
Typical examples are given for magnetrons u
