A transistor is a key component in electronics, often used as a switch or to amplify a signal from a sensor. NPN (negative-positive-negative) transistors are the most used transistor. An illustration ...

Thyristors are a semiconductor device with an S-shaped current-voltage characteristic. They are a kind of managed keys with a state memory that are turned on when a control signal is applied to the ...

“Two halves make a whole” is a very old and often true maxim. For example, it’s almost always true when said about AC phase angle power control. You rarely want significant alternating half-cycle ...

Physicists in Japan have made a thyristor -- a device that can convert a direct current into an alternating current -- from a single crystal of organic material. In addition to practical applications, ...

Have you ever wondered how some piece of digital technology developed? Or, what led up to some power electronics we take for granted today? Or, why we call something by a name that doesn’t seem to ...
