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 threeterminal 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.
