Over on YouTube [Lockdown Electronics] reviews an old bit of kit known as the Silicon Controlled Rectifier (SCR). Invented in the 1950s the SCR is a type of thyristor and they were popular back in the ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

Check out this link for On Semiconductor’s datasheet for a line of “Zero-Cross Optocoupled Triac Drivers.” The ability to zero-cross when turning on AC line voltage to some loads may be advantageous.

Makerfabs has recently introduced Matouch 1.28-inch ToolSet_AC Dimmer an open-source ESP32-based AC voltage controller for dimming lights or adjusting motor speeds using phase-cut dimming. Built ...

Fig 1. This efficient pre-regulator for a dc power supply uses an optical feedback loop to minimize dissipation rather than the traditional optically isolated TRIAC drivers. Fig 2. The PSpice ...

Abstract: This paper presents the simple and low-cost design of an automatic power factor correction (APFC) system for single phase domestic loads. The proposed design uses TRIACs to switch the ...
