Thyristors or silicon controlled rectifiers (SCR) as they
are sometimes known may appear to be unusual electronics
components in many ways, but they are particularly useful
for controlling power circuits. As such these electronics
components are often used for applications such as light
dimmers, and there may be thyristor circuits used in many
power supply applications. Thyristors are simple to use and
cheap to buy and often thyristor circuits are easy to build
and use. All these reasons make thyristors ideal components
to consider for many applications.
