chopper
any of several types of transistors having four semiconducting layers and therefore three p-n junctions; the thyristor is a solid-state analogue of the thyratron vacuum tube, and its name derives from the combination of the two words thyratron and transistor. A common form of thyristor is the silicon-controlled rectifier (SCR), used to convert alternating current (AC) to direct current (DC) and widely used as a component of devices that control motor speeds, liquid levels, temperatures, and pressures.
