Mention module of silicon controlled rectifier, people can think of it is one sort seems the thing at diode, but detailed action often is not special understanding, be in especially the action in circuit is more those who know is very little, relevant knowledge gains ground to everybody below, explain module of silicon controlled rectifier in detail the action in circuit.

 

Silicon controlled rectifier has two kinds commonly in the action in circuit, advocate if can accuse,rectification is mixed without contact switch.
 

 

Generally speaking, module of common silicon controlled rectifier can accuse rectification namely in the utility in circuit, more familiar like everybody diode commutate circuit is belonged to cannot dominate rectification circuit, if can change diode module of silicon controlled rectifier, can form can accuse excitation of timing of rectification circuit, inversion, electric machinery, electric machinery, without contact switch machine the application of the many respects such as automata. In electrical engineering technology, often be half cycle of alternating current 180 degrees, call electric angle, such is in of U2 every half weeks, begin to spark from 0 values the electric point of view that place of pulse arrival instant experiences becomes control horn α ; Be in every canal of half Zhou Neijing brake guides the electric point of view that understand makes guide θ of current flow angle. Apparent, α and θ are to be used state brilliant brake canal is in bear of half cycle to voltage guide connect or block snaps range. Control horny α through the change or guide θ of current flow angle, change the average UL of volts d.c. of the pulse on load, came true to be able to accuse rectification.

 

 

The action of module of silicon controlled rectifier also is rectification not just of course, it still can serve as will use without contact switch, better with facilitating put through quickly or cut off circuit, implementation turns dc into the inversion of alternating current, the alternating current that turns the alternating current of a kind of frequency into another kind of frequency is waited a moment.

 

Can see, it is very big that module of silicon controlled rectifier is returned in the action in circuit, module of silicon controlled rectifier can replace the control component of a few traditions already, for better use a few electric equipment and lay next solid foundations with report.
