Uburyo butandukanye bwo gufunga insinga bushobora kugira ingaruka ku bushobozi bwo gukwirakwiza imiyoboro ya transformer, ibyo bikaba bigira ingaruka ku buryo butaziguye ku mikorere ya transformer. Muri iyi nkuru, tuzibanda ku gipimo cya transformer.
Capacitance ikwirakwizwa ya transformer ni capacitance ya parasite iterwa no kuba hari itandukaniro rishoboka. Ni paramita y'amashanyarazi iboneka cyane, aho capacitance ikwirakwizwa hagati ya insulators ebyiri igihe cyose hari itandukaniro ry'amashanyarazi. Capacitance ikwirakwizwa nta ngaruka igira ku nsinga ku nsinga zo hasi, ariko ingaruka zayo zigomba kwitabwaho ku nsinga zo hejuru.
Ubushobozi bwo gukwirakwiza bwa transformer windings bushobora kugabanywamo ibice bine by'ingenzi:
(1) ubushobozi bwo guhindukira hagati y’imashini. Capacitor ikorwa n’itandukaniro rishoboka hagati y’imashini zegeranye. Nubwo agaciro k’ubushobozi hagati y’imashini imwe ari gato, kongera gushyushya no gusohora umuriro hagati y’imashini bishobora gutuma insinga zishyushya ndetse no kwangirika no kugabanuka k’uruziga rw’insinga zifite elayo mu buryo bukabije mu bihe bifite ingufu nyinshi cyangwa imbaraga nyinshi.
(2) Ubushobozi bwo gukwirakwiza ingufu hagati y’ibice bitandukanye. Ubushobozi bwo gukwirakwiza ingufu hagati y’ibice bitandukanye ni isoko nyamukuru y’ubushobozi bwo gukwirakwiza ingufu, bukora umuyoboro w’amazi urimo gusohora amazi ku murongo wo hejuru, bikongera ibibazo byo kubangamira ingufu za elegitoroniki no kongera imbaraga za voltage kuri transistor ihinduranya ingufu.
3) Ubushobozi bwo guhuza ibyuma. Ubushobozi bwo guhuza ibyuma hagati y’ibikoresho by’ibanze n’iby’inyongera, iby’ibanze n’iby’inyongera bya VCC, n’iby’inyongera na VCC. Iyi capacitor itanga inzira yo guhuza uburyo busanzwe bwo kubangamira ibyuma, bishobora gutuma urusaku ruturutse ku ruhande rw’ibanze rugera ku ruhande rw’inyongera, bigatera ingaruka ku buryo umusaruro uhagarara.
(4) Ubushobozi bwo guhindagurika. Ubushobozi bwo guhindagurika kw'imirongo ijya ku ngingo za rukuruzi, urwego rwo kurinda, cyangwa imiyoboro iterwa n'ibintu nk'uruziga, imiterere, cyangwa imiterere. Nubwo izi capacitor ari nto, zishobora kugira ingaruka ku miterere y'umuvuduko mwinshi munsi y'imiterere yihariye.
Ubushobozi bwo gukoresha transformer mu gukwirakwiza amashanyarazi akenshi burangiza, kandi ingaruka zabwo ku miyoboro ni izi zikurikira:
1. Ibibazo byo guhuza amashanyarazi. Capacitance ikwirakwijwe itanga inzira yo guhuza hagati y’impande zombi n’izombi, bigatera urusaku ku ruhande rwombi kugira ngo ruhuze n’uruhande rwombi binyuze mu mpande zombi, bigatuma habaho impurirane ihuriweho kandi ikangiza ubuziranenge bw’ikimenyetso cy’urukiramende.
2. Kugabanuka k'ubushobozi. Capacitors zikwirakwizwa mu miyoboro zishobora gukora imiyoboro itwara ingufu, bigatuma imbaraga zikora za transformers ziyongera ndetse n'ubushobozi bugabanutse muri rusange. Icya kabiri, inzira yo gusharija no gusohora ingufu zikwirakwizwa yongera igihombo, ubushyuhe bwo kuzunguruka buriyongera, kandi ubushobozi buragabanuka.
3. Kwangirika kw'ubushyuhe. Ubushobozi bwo gukwirakwiza amashanyarazi bushobora gutera ubwinshi bw'amashanyarazi mu gace runaka mu bihe by'amashanyarazi menshi, bigatuma umuriro uva ndetse n'ibikoresho byo gushyushya amashanyarazi bigabanuka.
4. Kugabanuka k'ubushobozi. Ubushobozi bwo gukwirakwiza no gusohora amazi bitera urujya n'uruza rw'amashanyarazi, bigatera imihindagurikire y'amashanyarazi mu buryo bwo guhindura amashanyarazi, bigatuma amashanyarazi arushaho kwiyongera kuri transistor ihindura amashanyarazi ndetse n'igikoresho kikangirika.
Mu mikoreshereze ya frequency nyinshi, capacitance ikwirakwizwa ishobora guhindura imiterere ya circuit ya transformers, bigatuma frequency response itandukana n'agaciro k'igishushanyo mbonera kandi ikagira ingaruka ku buryo circuit ihagaze. Capacitance ikwirakwizwa ishobora kandi kohereza urusaku rw'ingufu kuri terminal y'ibisohoka binyuze mu guhuza, kongera imbaraga z'amashanyarazi no kugabanya ubwiza bw'ibisohoka.
5. Inzitizi mu gushushanya no kwiyongera kw'ibiciro. Kugira ngo hagabanywe ingaruka z'ubushobozi bwo gukwirakwiza, bishobora kuba ngombwa gushushanya izindi RC buffer compensation circuits, ibyo byongera imiterere n'ikiguzi cy'igishushanyo mbonera cy'uruziga. Mu bihe byihuse, kugira ngo hagabanuke ubushobozi bwo gukwirakwiza, bishobora kuba ngombwa gukoresha ibikoresho bihenze cyane byo gukingira no gukora ibintu bigoye mu gushushanya transformers, bityo ikiguzi kikongera.
Mu ma-transformer afite frequency nyinshi, dushobora kugabanya ubushobozi bwo gukwirakwiza bwa transformer twongera intera iri hagati y’ingufu zizunguruka, twongera ubunini bw’ubushyuhe, dukoresheje ibikoresho byo gukingira bidahinduka bya dielectric, tunoza uburyo bwo gukingira, kandi twongera imiterere y’urwego rwo kurinda.
