Namuhla sihlola ukusetshenziswa komsebenzi wesifunda wangempela we-inductor, kumjikelezo wangempela ukusetshenziswa kwama-inductors ngokusebenzisa ukumelana kwe-low-frequency kuya ku-high-frequency, ngokusebenzisa ukumelana kwe-DC ezicini ze-AC zomklamo wamasekethe ahlukene, Okulandelayo sibheka i-inductor kumgomo wokusebenza kwe-DC-DC boost circuit.

1. Ukushintsha u-S kuvaliwe:

Njengoba kuboniswe kuMfanekiso 1, lapho inkinobho S ivaliwe, a, b, d akha iluphu evaliwe, ukunikezwa kwamandla ka-E nge-inductor kukhiqiza i-current encane kuya enkulu, ngalesi sikhathi t1 (njengomfanekiso 2 t1 → t2 ) imvamisa yamanje ijwayele ukuba seduze ne-high-frequency, ngokomthetho we-corrugator (ukwandisa i-anti-decrease ngokufanayo), i-inductor ikhiqiza i-current induced in the direction of the opposite current of the original current i, yamanje eyenziwe ivimbela ushintsho ku i, i-inductor idale ukuqondiswa kwamanje kwe-b → a, okusho ukuthi amandla akhona ku-inductor abe kumandla kazibuthe agcinwe kuze kube ngu-t2 lapho i-i yamanje inkulu, amandla okuvimbela nawo amakhulu, amandla kazibuthe agciniwe ku-inductor nayo inkulu kakhulu. Khona-ke i-t2 ngemva kokuba i-current ijwayele ukushelela, imvamisa yamanje ijwayele i-DC, ukuvinjelwa kwe-inductor kuba buthaka, amandla amanje ngokweqile ngokushintsha, ukwakheka kwe-loop evaliwe kugeleza ku-pole negative.Ungahlola izingxenye ezifanayo kusuka kuUhlu Lonke Lomkhiqizoukusetshenziswa kumasekhethi e-DC-DC.

2. Ukushintsha u-S nqamula:

Njengoba kuboniswe ku-Figure 3, lapho inkinobho S inqanyuliwe, a, b, d ayenzi iluphu evaliwe, ukunikezwa kwamandla ka-E kugeleza ku-inductor yamanje ngokushesha ukusuka ku-i enkulu kuya enkulu, ngalesi sikhathi t3 (njengakuMfanekiso 4 t3 → t4) imvamisa yamanje ivamise ukuba seduze ne-high-frequency, ngokomthetho we-corrugator (ukwandisa ukunqanda ukuncipha okufanayo), i-inductor ikhiqiza i-inductive current iqonde ohlangothini olufanayo ne-current i yasekuqaleni, i-current induced. ivimbela ukushintsha, isiqondiso se-inductor eyenzelwe i-a → b, okusho ukuthi ukunikezwa kwamandla I-current i in the inductor izobe isiphendule amandla kazibuthe aqala ukuguqulelwa ekubeni amanje, isiqondiso samanje ngokusebenzisa i-diode a → b → c → d, okungukuthi, i-voltage endaweni engu-b ye-electromotive force e-inductor eyenziwe kanye kanye ne-voltage yasekuqaleni yokuphakela amandla kagesi E, zihlangene nge-diode D1 ukuya ku-capacitance C yokushaja egcinwe, futhi ngesikhathi esifanayo, okukhiphayo. I-voltage kumthwalo we-U0, uma ungacabangi ukwehla kwe-voltage ye-diode, U0 = E + e. eyenga i-voltage ingavezwa ngosayizi wefomula A: Le fomula ikhombisa ukuthi usayizi we-voltage owenziwe kanye nosayizi we-inductance, izinga loshintsho lwamanje ngesikhathi seyunithi lingacutshungulwa ngokuqhubekayoIsikhungo Esishaukuze uthole imininingwane yobuchwepheshe.

Ngakho-ke ngalesi sikhathi i-voltage U0 iphakeme kune-voltage yokuhlinzeka E. Kuze kube ngu-t2 lapho i-yamanje incane kakhulu, amandla okuvimbela nawo amancane kakhulu, amandla kazibuthe agcinwe ku-inductor futhi ngokuyisisekelo ukuphela kokuguqulwa okusheshayo. Okulandelayo, ngokusebenzisa iswishi ihlale ivaliwe, inqanyuliwe, ungahlala ukhipha i-voltage U0, futhi i-voltage U0 iphakeme kune-voltage yokuhlinzeka ngo-E, ukuze udlale inhloso yokukhulisa.
