Namhlanje siphonononga ukusetyenziswa komsebenzi wesekethe wangempela we-inductor, kwisekethe yokwenyani kukusetyenziswa kwee-inductors ngokuxhathisa okuphantsi-frequency ukuya kwi-high-frequency, ngokuxhathisa kwe-DC kwiimpawu ze-AC zoyilo lweesekethe ezahlukeneyo, Ngokulandelayo sijonga i-inductor kwi-DC-DC yokukhuthaza umgaqo wokusebenza wesekethe.

1. Ukutshintsha u-S kuvaliwe:

Njengoko kubonisiwe kwi-Figure 1, xa iswitshi S ivaliwe, a, b, d yenza i-loop evaliweyo, unikezelo lwamandla u-E ngokusebenzisa i-inductor luvelisa i-current encinci ukuya enkulu, ngeli xesha t1 (njengoMfanekiso 2 t1 → t2 ) i-frequency yangoku ithande ukuba kufutshane ne-high-frequency, ngokomthetho we-corrugator (ukwandisa i-anti-ukwehla okufanayo), i-inductor ivelisa i-current induced kwicala elichaseneyo langoku i-original current i, i-current induced iphazamisa utshintsho kwi-inductor. i-i, i-inductor eyenzelwe ulwalathiso lwangoku lwe-b → a, okuthetha ukuba unikezelo lwamandla lwangoku kwi-inductor ukuya kumandla omagnetic agcinwe kude kube ngu-t2 xa umsinga ungowona mkhulu, amandla othintelo nawo awona makhulu, amandla ombane agciniweyo. kwi-inductor nayo inkulu. Emva koko i-t2 emva kokuba i-current ithande ukugudisa, i-frequency yangoku ithandeka kwi-DC, i-inductor obstruction iyancipha, i-excess current ngokusebenzisa i-switch, ukubunjwa kwe-loop evaliweyo ihamba kwi-pole negative.Yonke Uluhlu lwemvelisoukuze zisetyenziswe kwiisekethe ze-DC-DC.

2. Tshintsha u-S qhawula:

Njengoko kuboniswe kwi-Figure 3, xa i-S switch inqanyuliwe, a, b, d ayifaki i-loop evaliweyo, umbane wombane u-E uhamba nge-inductor yangoku ngokukhawuleza ukusuka kwi-inductor enkulu ukuya kwi-i enkulu, ngeli xesha t3 (njengoko kuMfanekiso 4). t3 → t4) i-frequency yangoku ithande ukuba kufutshane ne-high-frequency, ngokomthetho we-corrugator (ukwandisa ukuchasana nokunciphisa okufanayo), i-inductor ivelisa i-inductive current kwicala elifanayo njenge-original current i-induced current. Ithintela utshintsho, isalathiso se-inductor esenzelwe umsinga kwi- → b, nto leyo ethetha ukuba unikezelo lwamandla Okwangoku i-inductor iya kuba ijike amandla ombane aqale ukuguqulelwa ekubeni akhoyo, icala lomsinga kwidiode a → b → c → d, okt, amandla ombane kwindawo b ye-inductor eyenzelwe amandla e-electromotive e kunye nombane wokuqala wobonelelo lwamandla u-E, zikunye ngediode D1 ukuya kwi-Capacitance C yokutshaja egciniweyo, kwaye kwangaxeshanye, imveliso. i-voltage kumthwalo we-U0, ukuba awuyi kuqwalasela ukuhla kwe-voltage ye-diode, U0 = E + e. eye yabangela ukuba amandla ombane abonakaliswe ngobungakanani befomula ye-A: Le fomyula ibonisa ukuba ubungakanani bombane obunyanzeliswayo kunye nobungakanani be-inductance, isantya sotshintsho lwangoku ngexesha leyunithi inokuphononongwa ngakumbiIziko elitshakwimibono yobugcisa.

Ngoko ngeli xesha i-voltage ye-U0 iphezulu kune-voltage yokubonelela nge-E. Kuze kube ngu-t2 xa i-current i incinci, amandla okuthintela nawo awona mancinci, amandla ombane agcinwe kwi-inductor nawo ngokusisiseko uguqulo olukhawulezayo ekupheleni. Okulandelayo, ngokusebenzisa iswitshi ehlala ivaliwe, iqhawulwe, ungasoloko ukhupha i-voltage engu-U0, kwaye i-voltage U0 iphezulu kunombane wokubonelela ngo-E, ukuze udlale injongo yokunyusa.
