This circuit shows that dimmers intended for use at mains voltage do not always have to contain a triac. Here, a MOSFET (BUZ41A, 500 V/4.5A) in a diode bridge is used to control the voltage across an ...

Dimming of fluorescent lighting offers significant benefits – giving users control of their own lighting, and realizing energy savings. In certain environments dimming is a must, for instance in a ...

From what you would gather from Hackaday’s immense library of builds and projects over several years, the only way to do PWM is with a microcontroller, some code, a full-blown IDE, or even a real-time ...

If you buy something from a Verge link, Vox Media may earn a commission. See our ethics statement. Leviton’s entry into the market splits the pricing between the budget Aqara and the high-end Lutron ...

The ubiquitous triac dimmer can still work with LED lamps, thanks to new ICs. Energy-efficient lighting is in the headlines as we approach the date at which federally mandated efficiency levels for ...

The venerable 555-type timer makes an effective driver for power MOSFETs, but you have to understand the drive situation when selecting the correct variation of the basic timer. This idea shows how ...

DALLAS, USA : Texas Instruments introduced the industry's first floating switch architecture that simplifies the offline linear drive of LEDs in lamps, downlights and fixtures. The AC switched matrix ...
