Lamp dimmers and their circuits must be compact, energy efficient and able to operate reliably in confined spaces. Lamp brightness is varied by controlling the conduction time of each half-cycle of ...

In general terms, dimmers are devices that vary light level (intensity) of lamps by controlling the amount of power that is delivered to the lamp. Dimming can be controlled by either manual or ...

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

Several different technologies and designs are available among solid-state switches today. The major families are the standard Triacs (triode for alternating current), the snubberless Triacs, and the ...
