Modern light dimmers work by changing the duty cycle of the AC voltage which is applied to the lights being controlled. For instance, if the voltage is applied to half of the AC cycle, then the light ...

Abstract: The present investigations relate to the development of TRIAC-DIAC based DC series motor speed controller for mud pumps of industrial drill-rig equipment. This paper deals with mud pumps on ...

Simulating a triac or diac in LTSpice can be a challenge as these parts do not work straight out of the box. This video explains how to experiment with triacs and diacs in LTspice without ...

Re-Engineering a YLFC700 Fan Speed Controller (TRIAC based). This controller was originally sourced from an Xtrodinair Apex 42 Fireplace. The problem with the controller is that the slide ...

Triacs are at the heart of dimming controls for LED lighting. Triacs used in dimmers have normally been characterised and specified for incandescent lamp loads, which have high current ratings for ...

Modern power control systems utilize electronic devices like Thyristors for power switching, phase control, chopper etc. These devices also find applications in inverter design, brilliance control in ...

This light dimmer control has active timing capacitor reset or AC line zero-crossing synchronization. The 13 additional components are garden variety and cost less than $2. Performance at the low end ...

I have built this circuit on a zero PCB for testing it and my board after soldering all the components is looked like as shown in the image below. As you can see, the project looks simple and easy, so ...

This simple DIAC controlled flasher finds various industrial applications as a high-voltage indicator or machine-’on’ indicator. It flashes once every second to give a warning indication and is simple ...
