This SCR phase control works much like the common TRIAC dimmer, but has numerous advantages including increased current capability, robustness and absence of minimum voltage “snap-on.” A complementary ...

Fig. 1: The silicon-controlled rectifier One major aspect of development in broadcast transmitter technology and power electronics is in the area of power control. On the traditional transformer, we ...

SCRs are the switching devices for this unusual DC to DC converter that is suited for the ubiquitous 5V USB power source as well as numerous other applications. This novel power circuit topology uses ...

Permanent magnet dc motors need a chunky inductor in series with them if they are fed from an SCR (thyristor) based mains power controller. It is (probably!) possible to safely interface an Arduino to ...

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 ...
