Description
This evaluation board is a traditional design
solution for the control of a mono-phase motor or
any AC load-based motor. The solution is based
on phase-angle adjustment with a simple three-
terminal AC circuit (TRIAC) and a microcontroller
as a driver. These electronic devices are typically
used in home appliances or in industrial
applications, for various purposes such as motor
regulation and light dimming.
