module application range is very wide, mainly used in power supply equipment, is also common in life, but you know the current MTC thyristor module application?
To explain below, and see it together.
MTC thyristor module can be used in ac circuits, can also be used in the dc.
USES when dc dc can be shut off under the MTC thyristor, MTC thyristor module in the conduction of the primary loop where the fault, to meet the conditions of the primary loop current is less than its maintain current can be shut off, the general MTC thyristor module to maintain current in a few ma & ndash;
Dozens of ma range.
Control circuit, due to the alternating current had zero moment, MTC primary loop current is less than to maintain current thyristor module, thus can satisfy the shut off.
Can also be used to produce reverse current in a dc circuit makes the primary loop current moment less than maintaining current, and was shut off.
Communicate in MTC thyristor module control application is very wide, unijunction transistor ac voltage regulation circuit is a kind of typical ac voltage regulation circuit.
Regulating principle is: by changing the unijunction transistor trigger pulse of conduction Angle to control thyristor conduction time, to realize ac voltage regulation.
This circuit, the unijunction transistor is in ac circuits, through the half-wave rectifier and step-down to obtain working power supply.
Usually in regulating circuit, trigger circuit is produced by control circuit, control circuit work in dc.
In fact, don't need to explore whether dc control ac, as long as know MTC control principle of SCR module, its basic principle is to use the conduction of MTC thyristor trigger pulse control module, with smaller current control larger current to trigger the load of work.
