Unlike the SCR Phase Control Dimmer, I cannot claim ownership of the idea, but I am surprised that it seems to be buried and rarely utilized. This makes a great experimental circuit. Note that there ...

Most LED and CFL-driver circuits rely on coming up with a dimming circuit that can support a wide variety of triac dimmer switch types, but you’ll notice that in a lot of the “dimmable” lights you’ll ...

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 ...

Fairchild Semiconductor introduced the FL7730 single-stage primary side regulation (PSR) controller with power factor correction (PFC) for use with triac and analog dimming compatibilit ...
