The PIC controls dimming by delaying the time the triac fires, which trims the peaks off of the AC waveform. The PIC is powered by a large capacitor while the triac is conducting, preventing it ...

On that board he found a variable resistor combined with a capacitor which control a triac, actuating the speed of a drill. [Ben’s] solution works great and isolates the drill from the control ...

Description: control applications such as heating, lighting, and motor speed controls.Typical applications are AC solid-state switches, industrial power tools, exercise equipment, white goods and ...

These motors are often used for fans and can be varied in speed with TRIAC controls. AC Synchronous Motor Synchronous motors operate at constant speed up to full load. The rotor speed is equal to the ...
