From time to time I get requests to make some high power switching, so I decided to design a digital dimmer module that could handle a lot of different situations. The original requirements laid down ...

Mechanical relays, contactors, and switches control the flow of electricity by the mechanical action of two conducting elements. The physical contact of two conducting elements creates a path for ...

To understand the technology associated with practical LED dimming we first have to look at the technology associated with triac-based incandescent lamp dimmers. The typical triac lamp dimmer circuit ...

We are all familiar with the snap-on phenomenon of inexpensive TRIAC dimmers that are often used to control incandescent lamps –turn the pot until the light comes (snaps) on and then reduce the ...
