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 ...

Renesas was demoing a new approach to working with triacs at the LightSpeed booth at last week’s LightFair in Las Vegas: The circuit uses a Renesas microcontroller to learn each individual triac’s ...

The typical triac lamp dimmer circuit consists of the relatively simple circuit shown in Fig.1. Because the triac acts like two back-to-back silicon controlled rectifiers it can conduct in either ...

The FL7730 circuit is an active PFC controller for single-stage flyback topology application. The device supports both triac and analog dimming.

Here are helpful safety tips when wiring a light dimmer at home to control how much electricity your bulbs consume. Read the product's instructional manual properly before starting the project.
