What is the role of the SCR? One role is controlled thyristor rectifier, which is the most basic and most important SCR role. We know it can be done only diode rectifier circuit rectifier function, and not controllable, but once the diode for doing SCR SCR T435-600T, they constitute a controlled rectifier circuit. In a basic single-phase half-wave controlled rectifier circuit, when a sinusoidal AC voltage in the positive half cycle, the control electrode is applied only when the trigger pulse thyristor, thyristor trigger was only turned on, the load will have voltage output, so you can trigger pulse arrival time on the pole by changing the control to further regulate the average value of the output voltage to the load, to the role of controlled rectifier. Triac Schematics - aka "Triac" triac is a kind of monocrystalline silicon base material for P1N1P2N2 four three-terminal device SCR C106D, are developing on the basis of the ordinary and SCR into the AC switch device, the English name of the TRIAC that triac AC switch of Italy, was invented in 1957. Triac unidirectional conductivity switch can replace two parallel SCR reverse polarity, and only a trigger circuit. SCR has a turn-on and turn-off of two states, to distinguish from the appearance are: bolt-shaped, flat-shaped and flat-bottom shape categories. Because triac thyristor characteristics similar vacuum, so called silicon transistor gate through the international flow tube, called SCR T; and because thyristor controlled rectifier initially be applied aspects, it is also known as silicon controlled rectifying elements, referred to as the thyristor SCR.
