High power thyristor
module mentioned, people will think it is something similar to the diode, but the effect often is not particularly understand in detail, especially the role of the circuit is more little, below, silicon controlled rectifier manufacturer as to popularize the knowledge you, in detail the role of high power thyristor module in a circuit.
The role of thyristor in circuit, generally there are two, mainly controlled rectifier and non-contact switch.
Controlled rectifier: in general, common high power thyristor module used in the circuit is controlled rectifier, as everyone is familiar with diode rectifier circuit is controlled rectifier circuit, if you can swap diode for high power thyristor module, can constitute a controlled rectifier circuit, inverter, motor speed, motor excitation, non-contact switch machine, automatic control, and other applications.
In electrotechnics, alternating current (ac) half a cycle of 180 degrees, often referred to as the electrical point of view, so the U2 are each half cycle, from zero to trigger pulse arrival instant of electric Angle as control Angle alpha;
In each is half weeks thyristor conduction Angle of electric conduction Angle theta.
Obviously, the alpha and theta are used for high power thyristor module in the forward voltage under half cycle of the scope of the conduction or block.
By changing the control Angle alpha or conduction Angle theta, change the pulse dc voltage on load average UL, controlled rectifier is realized.
Non-contact switch: the effect of high power thyristor module, of course, is not only a rectifier, high power thyristor module also can be used as a non-contact switch, in order to better connect or cut off the circuit quickly, realize the dc into ac inverter, a frequency of the alternating current into another frequency alternating current (ac), and so on.
It can be seen that the role of high power thyristor module in circuit is very big still, high power thyristor module already can replace some traditional control element, to better use some electrical equipment and power to lay a solid foundation.
Zhejiang rectifier co. , LTD. , the production of various kinds of specifications models of thyristor module, MTC thyristor modules, solid state relay module, rectifier bridge module, such as supporting the radiator products, sincerely look forward to the cooperation with various companies and procurement staff, provide affordable, quality and reliable electronic components.
