Ụzọ waya dị iche iche nwere ike imetụta ike nkesa nke winding transformer, nke na-emetụta arụmọrụ nke transformer ozugbo. N'isiokwu a, anyị ga-elekwasị anya na paramita nke transformer.
Ike nke transformer kesara bụ ikike parasitic nke e mepụtara n'ihi na enwere ọdịiche nwere ike ịdị. Ọ bụ paramita eletriki dị ugbu a, ebe enwere ike nkesa n'etiti ihe mkpuchi abụọ ma ọ bụrụhaala na enwere ọdịiche voltaji. Ike nkesa anaghị emetụta sekit na obere ugboro, mana a ga-atụle mmetụta ya na ugboro ugboro dị elu.
Enwere ike kewaa ike nkesa nke windings transformer n'ime akụkụ anọ bụ isi:
(1) ike dị n'etiti ntụgharị. Ihe na-eme ka capacitor nke nwere ike ịdị iche n'etiti ntụgharị dị n'akụkụ. Ọ bụ ezie na uru ike dị n'etiti ntụgharị dị otu obere, ịchaji na ịtọpụ ugboro ugboro n'etiti ntụgharị nwere ike ibute mmebi mkpuchi na ọbụna mmebi na obere sekit nke waya enamel na ọnọdụ voltaji dị elu ma ọ bụ ike dị elu.
(2) Ike dị n'etiti oyi akwa. Ike dị n'etiti oyi akwa dị iche iche n'otu eriri. Ike dị n'etiti oyi akwa bụ isi iyi nke ike dị n'etiti, nke na-emepụta okirikiri oscillation yana inductance na-agbapụta n'ọtụtụ ugboro dị elu, na-eme ka nsogbu nnyonye anya elektrọnik ka njọ ma na-eme ka nrụgide voltaji dịkwuo elu na transistor mgbanwe.
3) Ike dị n'etiti. Ike dị n'etiti praịmarị na nke abụọ, praịmarị na VCC, na nke abụọ na nke VCC windings. Ike a na-enye ụzọ njikọ maka nnyonye anya ụdị nkịtị, nke nwere ike ime ka mkpọtụ sitere n'akụkụ praịmarị gaa n'akụkụ nke abụọ, na-emetụta nkwụsi ike mmepụta.
(4) Ike ndọda. Ike nke windings na cores magnet, oyi akwa nchekwa, ma ọ bụ casings na-akpata site na ihe dịka sekit, nhazi, ma ọ bụ nhazi. Ọ bụ ezie na capacitors ndị a dị obere, ha nwere ike inwe mmetụta na njirimara ugboro ugboro dị elu n'okpuru nhazi ụfọdụ.
Ike nkesa nke windings transformer na-emerụkarị ahụ, mmetụta ya na sekit bụ ndị a:
1. Nsogbu ndakọrịta elektrọnik. Ike kesara na-enye ụzọ njikọ n'etiti windings nke mbụ na nke abụọ, na-eme ka mkpọtụ dị n'akụkụ nke mbụ jikọọ na akụkụ nke abụọ site na capacitance, na-emepụta nnyonye anya ụdị nkịtị ma mebie iguzosi ike n'ezi ihe nke sekit ahụ.
2. Mbelata arụmọrụ. Kapasitọm kesara na sekit nwere ike ịmepụta ọkụ eletrik, na-ebute mmụba na ike mmeghachi omume nke transformers na mbelata na arụmọrụ zuru oke. Nke abụọ, usoro ịchaji na mwepụ nke ike kesara na-eme ka mfu ndị ọzọ dịkwuo elu, na-abawanye okpomọkụ na-agbagharị agbagharị, na-ebelatakwa arụmọrụ.
3. Mmebi mkpuchi. Ike kesara nwere ike ibute oke ọkụ eletrik mpaghara n'ọnọdụ voltaji dị elu, na-ebute mmụba nke mmiri na-agbapụta na ọbụna mmebi ihe mkpuchi.
4. Mbelata nguzosi ike arụmọrụ. Ike kesara na inductance na-emepụta sekit resonant, na-akpata mgbanwe voltaji na ike mgbanwe, na-ebute nrụgide voltaji gabigara ókè na transistor switching ma mebie ngwaọrụ ahụ.
N'ọrụ ugboro ugboro dị elu, ikesasị nwere ike ịgbanwe ụdị sekit nhata nke transformers, na-eme ka nzaghachi ugboro ugboro ghara ịdị na uru imewe ma na-emetụta nkwụsi ike sekit. Ikesasịsị nwekwara ike ibufe mkpọtụ switch na njedebe mmepụta site na njikọ, na-eme ka ripple ike dịkwuo elu ma na-ebelata mma mmepụta.
5. Mmachi imewe na mmụba ọnụ ahịa. Iji gbochie mmetụta nke ikesasị, ọ nwere ike ịdị mkpa imepụta sekit RC buffer ọzọ, nke na-eme ka mgbagwoju anya na ọnụ ahịa nke imewe sekit dịkwuo elu. N'ọnọdụ ugboro ugboro, iji belata ikesasị, ọ nwere ike ịdị mkpa iji ihe mkpuchi dị oke ọnụ na usoro dị mgbagwoju anya iji mepụta transformers, si otú a na-abawanye ọnụ ahịa.
N'ime transformers ugboro ugboro dị elu, anyị nwere ike ibelata ikike nkesa nke transformer site n'ịbawanye anya dị n'etiti windings, ịbawanye ọkpụrụkpụ mkpuchi, iji ihe mkpuchi dielectric na-adịgide adịgide dị ala, imeziwanye ụzọ winding, na ịbawanye nhazi oyi akwa nchekwa.
