Light Dimmer
The digital light dimmer is designed to control the light
intensity and on/off times for loads up to 20A at 220V and
can be used as firing circuit for high current SCRs for
larger loads. Control the light intensity from zero to full
power with 100 levels and the on/off time can by adjusted
digitally using the user interface. This design demonstrates
the idea of the digital phase control. This idea used in
many industrial applications as:

1- Light Dimming.
2- DC Motors speed control.
3- AC Motors Soft Starter.
4- Battery Chargers.
