Ukuhlaziywa kanye Nokukhethwa Kwesu Lokulungiswa Kwamandla Induction Isithando Somlilo

Njengoba ngesikhathi senqubo yokushisa yokungeniswa, imingcele elinganayo yomthwalo izoshintsha ngokushisa kanye nokuncibilika kokushaja kanye nezidingo zenqubo yokushisa, ukunikezwa kwamandla okushisa okufakwayo kufanele kukwazi ukulungisa amandla omthwalo. Njengoba ama-resonant inverter ochungechunge enezindlela eziningi zokulungisa amandla ahlukene, sidinga ukwenza izinqumo ezifanele enqubweni yokuthuthukisa ngokuya ngezinhlelo zokusebenza zangempela kanye nezidingo zokusebenza.

Izindlela zokulungisa amandla zohlelo zingahlukaniswa zibe izinhlobo ezimbili: ukulungiswa kwamandla ohlangothini lwe-DC kanye nokulungiswa kwamandla ohlangothini lwe-inverter.

Ukulawulwa kwamandla aseceleni kwe-DC ukulungisa amandla okukhiphayo we-inverter ngokulungisa i-amplitude ye-voltage yokufaka yesixhumanisi se-inverter ohlangothini lwamandla we-DC we-inverter, okungukuthi, imodi yokulawula amandla okulawula amandla kagesi (PAM). Ngale ndlela, umthwalo ungasebenza nge-resonance noma imvamisa yokusebenza eduze ne-resonance ngokusebenzisa izinyathelo zokuvala isigaba.

Kunezindlela ezimbili zokulungisa i-voltage ephumayo yesithando sokushisa sokungeniswa: ukulungiswa okulawulwa yisigaba noma ukulungisa okungalawuleki okulandelwa ukusika.

Ukulawulwa kwamandla ohlangothini lwe-inverter ukushintsha isimo sokusebenza esiphumayo se-inverter ngokulawula izici zokushintsha zamadivayisi wamandla wesixhumanisi se-inverter esilinganisweni se-inverter, ukuze kuqashelwe ukulawulwa kwamandla okukhiphayo we-inverter.

I-inverter side module module ingahlukaniswa ibe yi-pulse frequency modulation (PFM), i-pulse density modulation (PDM), kanye ne-pulse phase shift modulation. Lapho kwamukelwa uhlelo lokulungiswa kwamandla ohlangothini lwe-inverter, ukulungisa okungalawuleki kungasetshenziswa ohlangothini lwe-DC, okwenza kube lula isithando somlilo sokufudumeza esingenisa kabusha futhi sithuthukise isici samandla esiseceleni kwegridi iyonke. Ngesikhathi esifanayo, isivinini sokuphendula sokulungiswa kwamandla ohlangothini lwe-inverter siyashesha kunesohlangothini lwe-DC.

Ukulungiswa kokulawulwa kwesigaba nokulungiswa kwamandla kokushisa kwesithando somlilo kulula futhi kuvuthiwe, futhi ukulawula kulula; ukusebenza kahle nokuthembeka kokunikezwa kwamandla okulungiswa kwamandla e-chopper kuzoncishiswa ezimweni zamandla aphezulu, futhi akufanelekile ukusebenza okujwayelekile kokunikezwa kwamandla. I-Pulse frequency modulation izoba nomthelela omkhulu ku-workpiece yokushisa ngenxa yokuguqulwa kwemvamisa phakathi nenqubo yokulungisa amandla; i-pulse density modulation inozinzo olungeluhle ekusebenzeni kwamandla ezikhathini ze-loop evaliwe, futhi yethula indlela yokulungisa amandla enyathelwe; ukulungiswa kwamandla okushintsha kwesigaba se-pulse Ukwengeza ukulahleka kwamandla, njengokusebenzisa amaswishi athambile, kuzokhuphula inkimbinkimbi yesithando sokushisa esingeniswayo.

Ukuhlanganisa okuhle nokubi kwalezi zindlela ezinhlanu zokulungisa amandla, kuhlanganiswe nomsebenzi walesi sihloko ezimweni zamandla aphezulu, khetha ukusebenzisa ukulungiswa okulawulwa yisigaba se-thyristor ukuze kulungiswe amandla, futhi uthole isixhumanisi esiguquguqukayo se-DC okukhipha amandla kagesi ngokulungisa thyristor conduction angle. Ngaleyo ndlela ushintsha amandla okukhiphayo wesixhumanisi se-inverter. Lolu hlobo lwendlela yokulungisa amandla yesithando sokushisa sokungeniswa silula futhi sivuthiwe, futhi ukulawula kulula.
