ABB 5SHY35L4512 Asymmetric integrated gate
There are two wiring methods for improving the commutation of electric motors: armature reverse and magnetic field reverse. The former uses two sets of large capacity thyristor rectifiers to supply power to the motor armature, while the magnetic field is supplied by a set of small capacity thyristor rectifiers; The latter only uses a set of large capacity thyristor rectifiers to supply power to the motor armature, while the magnetic field is supplied in reverse parallel by two sets of small capacity thyristor rectifiers. The reverse connection of the armature has a fast action speed, but requires the use of an additional set of large capacity thyristor rectifiers;
Bidirectional thyristors, also known as three-terminal bidirectional thyristors, abbreviated as TRIAC MOS, are structurally equivalent to two unidirectional thyristors connected in reverse. These thyristors have bidirectional conduction function, and their on/off state is determined by the control pole G. Adding positive or negative pulses to the control pole G can make it conduct in the forward or reverse direction. one thousand four hundred and fifty-six
Controllable silicon has the advantages of small size, high efficiency, and long service life. In automatic control systems, it can be used as a high-power driver to control high-power equipment with small power. It has been widely used in AC/DC motor speed control systems, power regulation systems, and servo systems
