Mbido si n'aka radio na-amu amu: ịlele thyristor

Thyristor - a okporo ọkụ mmewere kpụrụ na a okporo ọkụ otu crystal isi na-enwe atọ ma ọ bụ karịa pn-junctions na abụọ anụ ekwu, sị: a steeti ala conductivity, nke a na-akpọ emechi; na a ala nke elu conductivity - oghe.

Novice radio na-amu amu nwere ike ịjụ ajụjụ a: "Olee otú bụ nkwenye nke thyristor" N'isiokwu a, anyị ga-ele anya na nke a usoro nke na-anwale a okporo ọkụ mmewere. Ọzọkwa, anyị na-atụle ihe dị mkpa tester thyristors.

E nwere ọtụtụ ụzọ maka anwale okporo ọkụ ngwaọrụ. Preliminary ego nke thyristor nwere ike rụrụ iji na-esonụ ngwá: a digital multimeter, tester ma ọ bụ ohmmeter. The mita ga-nyeere ke "continuity" nke diodes na tester mode nke iguzogide n'ihe. Na-enyemaka nke ndị a ngwaọrụ bụ omume na-elele ikwu n'ụzọ n'etiti thyristor n'ọnụ ụzọ ámá na cathode na n'etiti ndị anode na cathode. The uru nke ndị na-eguzogide nke okporo ọkụ mmewere nke mgbanwe n'etiti ọnụ ụzọ ámá, cathode ga 50-500 ohms. The uru nke a na-eguzogide bụ mkpokọta otu dị ka atụ na agbara n'ihe. The elu na-eguzogide uru, ndị ọzọ mwute okporo ọkụ thyristor. Na ndị ọzọ okwu, ngwaọrụ ga-a obere ugbu a bara uru na-achịkwa electrode, ka kwapụ mechiri emechi na-emeghe ala. Ezughị oke thyristor nwere a na-eguzogide uru n'etiti ndị electrodes ka anode-cathode n'oge na-atụ na n'oge reverse metering nēche ebighebi.

Preliminary ego nke thyristor enye puru na a abụọ n'aka okporo ọkụ mmewere nwere ike nkejikotara a gbara ọkụ mgbanwe cathode-anode. Atụ ihe dị otú ahụ nsogbu nwere ike ghara kpebisiri ike.

Isi thyristor ego a rụrụ na ihe ndị ọzọ ike isi mmalite. Mgbe ihe dị otú ahụ ime ihe na kpamkpam tutu amama nsogbu nke okporo ọkụ ngwaọrụ. The thyristor abatakwa na-emeghe ala, ma ọ bụrụ na ndị cathode - akara electrode - Ikwu obere usu achọrọ maka oghere mmewere. N'ihi na nke a na atụmatụ a na-aga iji nwalee thyristors. ọtụtụ nwere ike kpọkọtara ndị dị otú ahụ atụmatụ, tụlee ihe kasị elementrị. Iji mee nke a, na-eji a ike esenyịn, egosi oriọna, abụọ switches na resistors. Circuit nwere ike kpọkọta na a ule osisi ma ọ bụ na-ebe wiring. Anakọta atụmatụ mwepu ike (5-25 V) etinyere na cathode nke thyristor. Plus iyi site na-ejikarị emechi isi K1 na via ngosi ìhè na ngwaọrụ anode. Iji mmepụta nke akara electrode itinye resistor, nke abụọ kọntaktị bụ site ejikari oghe button K2 jikọọ n'etiti oriọna na isi K1. Ndị na-eguzogide uru a họọrọ na-atụ anya na nke ugbu a eruba bụ zuru ezu iji rụọ ọrụ na ngwaọrụ. All atụmatụ dị njikere, na-amalite ule. N'ihi na nke a closable isi K2, akara ugbu a ga na-aga site circuit si plus button site K1 na K2 via a resistor, via ya akara electrode na cathode na mwepu isi iyi. Thyristor emepe. K2 button a tọhapụrụ. Egosi oriọna. Push button K1 ejikari emechi, ibu ugbu a site na thyristor circuit bipụ ya, na ọ na-emechi. Oriọna na-apụ, na-circuit na mbụ ala.
