Enkola ya chajingi ya chajingi kye ki?
Enkola y’okucaajinga eya chajingi .
Ekitundu kino kiraga omusingi gw’okucaajinga ogw’ebisannyalazo nga kyawula ebyokulabirako by’ensengekera za topologiya ez’enjuyi za chajingi ez’oludda olumu n’ez’enjuyi ebbiri.
topology y’okucaajinga ey’oludda olumu .
Charger etegeera okukyusa wakati wa AC ne DC ng’eyita mu byuma eby’amasannyalaze eby’amasannyalaze. Tekyewalika, ebyuma eby’amasannyalaze eby’amasannyalaze bireeta amaanyi agakola, era amaanyi agasukkiridde agakola gayinza okuvaako enkyukakyuka za vvulovumenti z’amasannyalaze, okukendeeza ku mutindo gw’amasannyalaze, n’okwongera okufiirwa layini. Omugerageranyo gw’amaanyi agakola n’amaanyi agalabika mu nkulungo gutegeezebwa nga ensonga y’amaanyi. Okuziyiza amaanyi agasukkiridde agakola agaweebwa enkomerero-omukozesa ku mudumu gw’amasannyalaze, obukwakkulizo obukakali ku nsonga y’amasannyalaze buteekebwawo ku masannyalaze gombi ag’okusulamu n’aga makolero, ebiseera ebisinga tebiri wansi wa 0.8~0.9. Emu ku nkola ezikolebwa ye tekinologiya wa PFC (power factor correction), asobola okumalawo obucaafu bwa harmonic okuva mu byuma eby’amasannyalaze eby’amasannyalaze n’okulongoosa ensonga y’amasannyalaze agayingira.
Tekinologiya wa PFC ow'omuggo omu (0}}Single{-Full full-Bridge PFC awaayo enkizo nga ensengekera ennyangu, obulungi obw'amaanyi, n'okusitula okusikirizibwa kwa waggulu-Frequency nga kuliko emirundi ebiri-okusikirizibwa, ekigifuula esaanira okukozesebwa okw'amaanyi okwa waggulu-. Omutendera gumu-ogujjula-omutala PFC converter nga gwesigamiziddwa ku nsengekera ya bridge mu bujjuvu-eragiddwa mu kifaananyi 11-21. Ekola mu masaza abiri:Okutambuza emikono waggulu ne wansi .neOkwolekera okutambuza emikono .. Mu kiseera ky’okutambuza emikono waggulu ne wansi, akasannyalazo mu input inductor kasituka. Mu kiseera ky’okutambuza emikono okw’enjawulo, akasannyalazo mu input inductor kagwa. Enkola y’okufuga etereeza omugerageranyo (enzirukanya y’emirimu) ey’obudde bw’okutambuza emikono waggulu n’egya wansi mu nsengekera y’okucaajinga n’okufuluma kwa inpuctor eyingiza okutereeza obunene bwa current mu input inductor, ekifuula input current a sine wave mu phase ne voltage eyingizibwa. Kino ku nkomerero kimalawo waggulu-order current harmonics era kituuka ku power factor correction.
Okwekenenya enkola y’okutambula kw’amasoboza, kiyinza okulabibwa nti mu kiseera ky’okutambuza emikono waggulu n’okunsi, vvulovumenti okubuna-enkyusa ya frequency eya waggulu eri 0, era capacitor ya ffilta efuluma egaba amaanyi ku mutwalo; Mu kiseera ky’okutambuza emikono egy’enjawulo, Transformer eya waggulu-ekyusa amaanyi agaterekeddwa mu input inductor n’egiwa .
Amasoboza agava mu waya y’okuyingiza gakyusibwa ne gateekebwa ku ludda olw’okubiri olwa tulansifooma. Oluvannyuma lw’okutereeza n’okusengejja emirundi mingi-, kiwa amaanyi ku mutwalo. Nga tutereeza duty cycle ya system, output voltage esobola okukyusibwa, okukuuma output voltage ku rated value. Mu nsengekera emu ey’okukola, inpuctor inductor emaliriza enzirukanya bbiri eza charge ne discharge, era high-frequency transformer ecamuka emirundi ebiri, nga endagiriro z’okusikirizibwa ebbiri ziri ku kikontana. Kino kikozesa omusingi gwa magineeti mu ngeri y’okusika-okusika, okulongoosa omuwendo gw’okukozesa omusingi gwa magineeti ogwa tulansifooma.
topology y’okucaajinga ey’ebitundu bibiri .
Ekifaananyi 11-22 kiraga ensengekera ya topologiya y’enkulungo enkulu ey’okucaajinga n’okufulumya chajingi ey’enjuyi ebbiri, omuli ekisengejja kya PWM eky’ekika kya PWM ekya PWM ekya PWM n’ekikyusa DC/DC eky’enjawulo eky’enjawulo eky’omutala n’omukyusa DC/DC ow’oludda olubiri.
Ensonda z’amasannyalaze ssatu-Phase AC zitera okukozesebwa mu makolero aga waggulu -Voltage ne High-amaanyi. Bidirectional kitegeeza nti amaanyi agakulukuta gayinza okuva ku ludda lwa giridi okutuuka ku bbaatule y’emmotoka, oba okuva ku ludda lwa bbaatule okutuuka ku ludda lwa giridi. Ekitundu ekisatu-kitundu kya phase-ekiziyiza-Ensibuko ya PWM etereeza mu kifaananyi kika kya bidikizo bibiri eby’okutereeza PWM, ekirina ebirungi ng’okutuuka ku ntambula y’amasoboza ag’enjuyi ebbiri, okuddamu okw’amaanyi okw’amaanyi, n’okukola obulungi-embeera y’embeera. bwe kiba mu .Embeera y’okutereeza ., amasoboza gakulukuta okuva ku ludda lwa giridi, akasannyalazo ka sinusoidal, era phase yaayo y’emu ne vvulovumenti ya giridi; bwe kikola mu .Embeera y’okukyusakyusa ., Amasoboza agaterekeddwa mu bbaatule y’emmotoka ey’amasannyalaze galiisibwa okudda ku giridi y’amasannyalaze, ate ekisengejjero ky’amasannyalaze ku mabbali n’amayengo ga kasasiro byombi biba bya sinusoidal, nga enjawulo ya phase ya 180℃.
Bidirectional DC/DC converter erina enkizo nga FAST DYNATIC RESPONS, high energy conversion efficiency, n’ebyuma by’amasannyalaze ebitono. Nga bwe kiragibwa mu kifaananyi 11-22, chajingi bw’eba ecaajinga bbaatule y’emmotoka ey’amasannyalaze, switch .S1ali mu kukola, ate switch .S2bulijjo kivaako. N’olwekyo, ekitereeza PWM eky’enjuyi ebbiri kikola mu mbeera y’okutereeza, era ekikyusa DC/DC eky’enjuyi ebbiri kiri mu ddaala-embeera ya buck wansi, era amasoboza gakulukuta okuva ku ludda lwa giridi okutuuka ku ludda lwa bbaatule; Battery bweba efulumya, switch .S2is off, switch .S1is conducting, bidirectional DC/DC converter eri mu mutendera-Up boost state, era bidirectional PWM rectifier ekola mu active inversion state, era amaanyi agaterekeddwa mu bbaatule galiisibwa okudda ku power grid okuyita mu rectifier.
