Ebumnuche bụ isi nke thyristor na sekit?

Kacha isi ojiji nke nkịtị silicon nkịtị rectifiers na-achịkwa rectifiers. Sekit rectifier maara nke ọma bụ sekit rectifier na-enweghị nchịkwa. Ọ bụrụ na ejiri silicon na-achịkwa rectifier dochie diode, enwere ike ịmepụta sekit rectifier na-achịkwa. Otu n’ime sekit rectifier na-achịkwa nke otu nkeji kacha mfe. N’oge ezi ọkara okirikiri nke sinusoidal AC voltaji u2, ma ọ bụrụ na njikwa eletrọd nke VS etinyeghị triga pulse ug, VS ka enweghị ike ịgbanwuo. Naanị mgbe u2 nọ na ọkara okirikiri ziri ezi na ihe na-akpali akpali ug na-etinye aka na electrode njikwa, thyristor na-eme ka gbanye ya. Ọ bụrụ na ug rutere n’isi ụtụtụ, thyristor ga-agbanye n’isi ụtụtụ; Ọ bụrụ na ug bịarutere n’oge, thyristor ga-agbanye n’oge. Site n’ịgbanwe oge mbata nke ihe na-akpali akpali ug na ogwe njikwa, nkezi uru ul nke mmepụta voltaji na ibu nwere ike gbanwee. Na nkà na ụzụ, ọkara okirikiri nke alternating current na-emekarị ka ọ bụrụ 180 °, nke a na-akpọ akụkụ eletrik. N’ụzọ dị otú a, na nke ọ bụla ziri ezi ọkara okirikiri nke u2, eletriki n’akuku nwetara site efu uru na oge nke triga usu a na-akpọ akara angle α; Akuku eletrik nke thyristor na-eduzi na ọkara okirikiri nke ọma ka a na-akpọ angle conduction θ. N’ụzọ doro anya, a na-eji ma α na θ na-egosi nhazi ma ọ bụ nkwụsị nke thyristor n’oge ọkara okirikiri nke voltaji na-aga n’ihu. Site n’ịgbanwe njikwa njikwa α ma ọ bụ ihe ntụgharị θ, nkezi uru ul nke pulse DC voltaji na ibu na-agbanwe, na nhazi nke njikwa na-emezu. N’ime sekit rectifier akwa akwa, ọ bụ naanị diode abụọ ka a ga-eji ihe ndozi silicon na-achịkwa iji mepụta sekit rectifier zuru oke.
