Sometimes, the control circuit has also to be insulated from the mains voltage. This occurs, for example, when the MCU reference is not the same than the AC switch reference. This is the case with new ...

The problem of compatibility lies in how the triac dimmer circuit interacts with the input circuitry of the LED driver. Figure 2 – Basic LED driver circuit blocks. The single stage LED driver example ...

It’s a wonderful thing to see a clever hack repair instead of disposing of a product. The best repair approach is finding exact replacement components, but sometimes exact components can’t be… ...

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 J MAX of 125°C will not be ...
