Silicon controlled rectifiers (SCRs), also known as thyristors, are semiconductor devices that can be used to switch or control AC current. The thyristor conducts in one direction when triggered by a voltage applied to its gate. It continues to conduct until the current through the thyristor reaches zero. It then blocks any further current until it is triggered again. This makes it useful to control AC power for which the thyristor is triggered during one cycle and blocks again after the cycle current goes to zero.
