Because the triac acts like two back-to-back silicon controlled rectifiers it can conduct in either direction. Therefore, the triac dimmer circuit cuts both halves of the ac sine wave input, as ...

Designing an AC circuit for controlling LED light output is very simple when using the newest triac designs, such as the Littelfuse Q6008LH1LED or Q6012LH1LED Series, because the only components ...

A triac is used in a discrete phase-control circuit to control the speed of a vacuum-cleaner motor. Confirm by calculating for worst-case conditions that the triac's T JMAX of 125°C will not be ...

These deficiencies result from the fact that the vast majority of dimmers installed in the US are based on the triac-based two-wire leading edge phase cut circuit developed in the 1960s intended for ...

These devices are all triggered thanks to a gate current, but this current could be sunk from or sourced to the gate, depending on the technology or design. The triggering circuit has then to take ...
