The project is designed to control the speed of an induction motor such as fans, by using a standard TV remote. In home automation application, convenience of remotely controlling the speed of the fan ...

The project is designed to control AC power to a load by using firing angle control of thyristor. Efficiency of such power control is very high compared to any other method. The project is designed to ...

Precision temperature control circuits for small thermal loads like oscillator crystals and voltage references tend to be fairly easy to design. This is because simple, well-behaved, linear-output ...

America Semiconductor’s 25RIA Series of medium power, phase control thyristors are single-phase silicon controlled rectifiers (SCR) supplied in a standard TO-48 package. With a current handling ...

SCR speed controllers that supply 180Vdc motors from 240Vac mains are wonderfully robust, but have the drawback that they always present fast-rising voltage edges to the motor’s armature at a 100Hz ...

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 ...

Last month I talked about the problem of subsynchronous resonance (SSR) and the dynamic stabilizer as a solution. The stabilizer was basically an early thyristor-controlled reactor (TCR) device that ...
