(1) Izinzuzo ze-adaptha yamandla
I-adaptha yamandla iwukunikezwa kwamandla okuguqula imvamisa emile okuhlanganisa izingxenye zamandla ze-semiconductor. Kuwubuchwepheshe bokuguqula imvamisa emile obuguqula imvamisa yamandla (50Hz) ibe ifrikhwensi emaphakathi (400Hz ~ 200kHz) nge-thyristor. Inezindlela ezimbili zokuguqula imvamisa: i-AC-DC-AC frequency conversion kanye ne-AC-AC frequency conversion. Uma kuqhathaniswa nesethi ye-generator yamandla yendabuko, inezinzuzo zemodi yokulawula eguquguqukayo, amandla amakhulu okukhiphayo, ukusebenza kahle okuphezulu, ukuguqulwa kwemvamisa yokusebenza okulula, umsindo ophansi, ivolumu encane, isisindo esincane, ukufakwa okulula nokusebenza okulula nokugcinwa. Isetshenziswe kabanzi ezintweni zokwakha, i-metallurgy, i-National Defence, ujantshi, i-petroleum nezinye izimboni. I-adaptha yamandla inokusebenza kahle okuphezulu kanye nemvamisa eguquguqukayo. Ubuchwepheshe obuyinhloko kanye nezinzuzo ze-adaptha yamandla yesimanje zimi kanje.
(2) Imodi yokuqala ye-adaptha yamandla yesimanje isebenzisa imodi yokuqalisa ethambile yokushanela ifrikhwensi enguziro ngendlela yesinye isasasa ukuya ekuzijabuliseni. Kuyo yonke inqubo yokuqala, isistimu yokulawula imvamisa kanye nesistimu yamanje kanye ne-voltage regulation clop-loop ilandelela ukushintsha komthwalo ngaso sonke isikhathi ukuze ibone isiqalo esithambile esifanelekile. Le modi yokuqala inomthelela omncane ku-thyristor, okulungele ukwandisa impilo yesevisi ye-thyristor. Ngesikhathi esifanayo, inezinzuzo zokuqala kalula ngaphansi komthwalo okhanyayo nonzima, Ikakhulukazi lapho isithando somlilo sokwenza insimbi sigcwele futhi sibanda, singaqalwa kalula.
(3) Isekethe yokulawula ye-adaptha yamandla yesimanje isebenzisa isekethe yokulawula amandla e-microprocessor kanye ne-inverter Ф Isekhethi yokulungisa i-angle ingakwazi ukuqapha ngokuzenzakalelayo izinguquko ze-voltage, zamanje kanye nemvamisa nganoma yisiphi isikhathi phakathi nokusebenza, ihlulele ukushintsha komthwalo, ilungise ngokuzenzakalelayo ukufaniswa kokuvinjelwa komthwalo kanye nokuphuma kwamandla okungaguquki, ukuze kufezwe injongo yokonga isikhathi, ukonga amandla nokuthuthukisa isici samandla. Inokonga amandla okusobala kanye nokungcoliswa kwegridi yamandla amancane.
(4) Umjikelezo wokulawula we-adaptha yamandla yesimanje yakhelwe isofthiwe ye-CPLD. Ukufakwa kohlelo lwayo kuqedwa ngekhompyutha. Inokushaya kwenhliziyo okuphezulu, ukumelana nokuphazamiseka, isivinini sokuphendula ngokushesha, ukulungisa iphutha, futhi inemisebenzi eminingi yokuvikela njengokunqanyulwa kwamanje, ukunqanyulwa kwe-voltage, i-overcurrent, overvoltage, ukungasebenzi kahle kanye nokuntuleka kwamandla. Ngenxa yokuthi ingxenye ngayinye yesifunda isebenza njalo phakathi kwebanga eliphephile, impilo yesevisi ye-adaptha yamandla ithuthukiswa kakhulu.
(5) I-adaptha yamandla yesimanje ingahlulela ngokuzenzakalelayo ukulandelana kwesigaba somugqa ongenayo wezigaba ezintathu ngaphandle kokuhlukanisa ukulandelana kwesigaba sika-a, B kanye no-C. ukulungisa iphutha kulula kakhulu.
(6) Amabhodi wesekethe wama-adaptha amandla esimanje wonke enziwa ngokushisela okuzenzakalelayo kwe-wave crest, ngaphandle kokushisela okungamanga. Zonke izinhlobo zezinhlelo zokulawula zisebenzisa umthethonqubo we-elekthronikhi ongathinteki, ongenawo amaphuzu wephutha, izinga lokwehluleka eliphansi kakhulu kanye nokusebenza okulula kakhulu.
(7) Ukuhlelwa kwama-adaptha amandla
I-adaptha yamandla ingahlukaniswa ngohlobo lwamanje kanye nohlobo lwe-voltage ngokuya ngezihlungi ezihlukene. Imodi yamanje ihlungwa nge-DC smoothing reactor, engathola i-DC eqondile ngokuqhathaniswa. Umthwalo wamanje uyigagasi elingunxande, futhi umthamo womthwalo ucishe ube yi-sine wave; Uhlobo lwe-voltage lusebenzisa ukuhlunga kwe-capacitor ukuze kutholwe i-DC voltage eqondile. I-voltage emikhawulweni yomibili yomthwalo iyigagasi elingunxande, futhi amandla okulayisha acishe abe yi-sine wave.
Ngokwemodi ye-resonance yokulayisha, i-adaptha yamandla ingahlukaniswa ngohlobo lwe-resonance ehambisanayo, uhlobo lwe-resonance yochungechunge kanye nochungechunge oluhambisana nohlobo lwe-resonance. Imodi yamanje ivame ukusetshenziswa kumasekhethi e-parallel resonant resonant; Umthombo wamandla kagesi usetshenziswa kakhulu kumjikelezo we-resonant inverter.
