Maitiro ekuona inodzorwa kugadziriswa ne SCR (thyristor)?

Iyo inonyanya kushandiswa kweyakajairwa silicon inodzorwa rectifiers inodzorwa kugadzirisa. Iyo yakajairika diode rectifier wedunhu isingadzoreki rectifier redunhu. Kana iyo diode ikatsiviwa nesilicon inodzorwa rectifier, inodzorwa inodzoreredza wedunhu inogona kuumbwa. Ini ndinodhirowa yakapfava imwe-chikamu hafu-wave inodzoreka rectifier wedunhu. Munguva yehafu yakanaka kutenderera kwe sinusoidal AC voltage U2, kana danda rekudzora reVS rikasapinza iyo inokonzeresa pulse Ug, VS haisati yabatidzwa. Chete kana U2 iri muchikamu chakanaka chehafu uye chinokonzeresa pulse Ug chikaiswa padanda rekudzora, thyristor inokonzereswa kuti ibatike. Dhirowa waveform yayo, iwe unogona kuona kuti chete kana iyo trigger pulse Ug yasvika, iyo voltage UL inobuda pamutoro RL. Ug inosvika mangwanani, uye SCR inovhurwa kare; Ug inosvika kunonoka, uye SCR inobatidzwa kunonoka. Nekushandura nguva yekusvika kweiyo trigger pulse Ug padanda rekudzora, avhareji kukosha UL (nzvimbo yenzvimbo ine shaded) yemhepo inobuda pamutoro inogona kugadziriswa. Muinjiniya yemagetsi, hafu yekutenderera yealternating ikozvino inogadzika se 180 °, iyo inonzi magetsi angle. Nenzira iyi, mune imwe neimwe yehafu yakanaka yeU2, kona yemagetsi inowanikwa kubva kune zero kukosha kusvika panguva ye trigger pulse inonzi control angle α; kona yemagetsi iyo thyristor inobata mune imwe neimwe yakanaka hafu inotenderera inonzi conduction angle θ. Zviripachena, ese ari maviri α uye θ anoshandiswa kuratidza conduction kana kuvharira huwandu hwe thyristor panguva yehafu yekutenderera yemhepo yekumberi. Nekushandura kona yekudzora α kana iyo conduction angle θ, avhareji kukosha UL yepulse DC voltage pamutoro inoshandurwa, uye inodzoreka kugadzirisa kunoitika.
