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 ...

Chromalox, Pittsburgh, recently released a revised edition of its SCR Power Theory Training Manual. The free, 40-page illustrated manual on silicon controlled rectifier (SCR) power controllers has ...

Although the silicon controlled rectifier or SCR has been around since 1957, it doesn’t get nearly the love an ordinary transistor does. That’s a shame because they are quite handy when it comes to ...

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 ...

America Semiconductor announced the ASCT625A Series of (SCRs). The 25 A, single-phase SCRs are provided in a standard TO-220A package, and feature a high ability to withstand the shock loading of ...

SCRs (silicon-controlled rectifiers), or thyristors, have higher current and voltage ratings, lower conduction losses, and more robustness than triacs. For these reasons, SCRs are better suited to ...

As electronic sub-systems play a significant role in the reliable and safe operation of the overall product, adding an overvoltage protection (OVP) circuit around the DC/DC step-down regulator may be ...
