SCR SCR can be achieved in the circuit AC non-contact control, a small current to control high current, and not as controlled as the spark generated when the relay, and the fast, long life and reliability. In speed, dimming, voltage regulators, thermostats, and other various control circuits has its presence. SCR is divided into one-way and two-way, the symbol is different. There are three-way thyristor SCR PN junction, from the outermost P and N poles leads to two electrodes, called the anode and cathode, by the middle of the P-pole leads to a control electrode. Way thyristor has its unique features: When reverse voltage anode, or positive anode voltage control pole but no voltage when it is not turned on, and an anode and a control electrode connected to a positive voltage at the same time, It will be turned on. Once turned on SCR T405-600T, control voltage has lost its control action, with or without control voltage thyristor T405-800T, regardless of how the polarity of the control voltage SCR 2P4M, stays in lead state. To shut off, and only the anode voltage is reduced to a critical value, or reverse. Most triac pin is sequentially T1, T2, G from the left to right (the electrode pins down, there is a character of one side of the face). When the trigger pulse applied to the control electrode G of the size or time changes, will be able to change the size of on-current. SCR SCR module chip from X point of view, can be divided into controlled rectifier module and two categories; distinction from the specific uses can be divided into: ordinary thyristor modules (MTC \ MTX), ordinary rectifier module (MDC), ordinary thyristor rectifier hybrid module (MFC), fast thyristor, rectifier and hybrid module (MKC \ MZC), non-insulated thyristor rectifier and hybrid modules (also known as the welding machine-specific modules MTG \ MDG), the three-phase bridge rectifier output thyristor modules (MDS), single-phase (three-phase) rectifier bridge modules (MDQ), single-phase half-bridge (Three Phase Bridge) module (MTS) and Schott base module.
