Abahlinzeki be-Special frequency converter bayakukhumbuza ukuthi ngokusetshenziswa okwandayo kweziguquli zefrikhwensi, ukusebenza kwazo nobuchwepheshe nakho kukhula ngokushesha, kuboniswa ikakhulukazi kulezi zici ezilandelayo:
(l) I-modularization. Ukwenziwa kwemodular kweziguquli zefrikhwensi ezintsha kwenze inqubekelaphambili enkulu. I-Integrated Power Module (ISPM) yeziguquli zemvamisa yenjongo evamile ihlanganisa amasekhethi alungisa kabusha, amasekhethi okushintshashintshashintshayo, amasekhethi okulawula okunengqondo, amasekhethi okushayela nokuvikela, namasekhethi amandla abe yimojula eyodwa, kuthuthukisa kakhulu ukwethembeka.
(2) Ubungcweti. Ukuze kusetshenziswe kangcono ubuchwepheshe baso bokulawula obuhlukile futhi kuhlangatshezwane nezidingo zokulawula endaweni ngangokunokwenzeka, isiguquli sefrikhwensi esisha sithole amamodeli amaningi akhethekile, afana nefeni, iphampu yamanzi, amamodeli akhethekile ayisiphephetha-moya, amamodeli akhethekile omshini wokubumba umjovo, namamodeli ayisipesheli esikheshi Akhethekile emishini yendwangu, idrayivu yefrikhwensi ephakathi nendawo, i-locomotive traction, njll.
(3) Isoftware esekelwe. Ukusebenza okusekelwe kwisofthiwe yesiguquli sefrikhwensi entsha kungene esigabeni esisebenzayo, futhi imisebenzi edingekayo ingafinyelelwa ngohlelo lwesofthiwe olwakhelwe ngaphakathi. Isiguquli sefrikhwensi sifakwe isoftware ehlukahlukene yokuzikhethela ukuze sihlangabezane nezidingo zokulawula inqubo ekusayithi, njengesofthiwe yokulawula i-PID, isofthiwe yokulawula ukushuba, isofthiwe yokulawula ukuvumelanisa, isofthiwe elandela isivinini, isofthiwe yokulungisa iphutha yesiguquli, isofthiwe yokuxhumana, njll.
(4) Inethiwekhi. Isiguquli sefrikhwensi esisha sifakwe isixhumi esibonakalayo se-RS485, esingahlinzeka ngezindawo zokuxhumana eziningi ezihambisanayo futhi sisekele izinqubo zokuxhumana ezihlukene. Isiguquli sefrikhwensi singalawulwa futhi sisetshenziswe yikhompyutha, futhi singaxhumana namanethiwekhi ahlukahlukene e-fieldbus njenge-Lonworks, Interbus, Device et, Modbus, Profibus, Ethernet, CAN, njll. ngokusebenzisa izinketho. Futhi ingasekela ezimbalwa noma zonke izinhlobo ze-fieldbus ngokusebenzisa izinketho ezinikeziwe.
(5) Umsindo ophansi we-electromagnetic kanye nokuthula. Isiguquli sefrikhwensi esisha samukela indlela ye-SPWM yenkampani yefrikhwensi ephezulu ukuze kuzuzwe ukuthula. Kumjikelezo we-inverter, ubuchwepheshe bamanje bokulawula ukuwela u-zero busetshenziselwa ukuthuthukisa i-waveform, ukunciphisa ama-harmonics, nokuhambisana nezindinganiso zamazwe ngamazwe ngokuhambisana kwe-electromagnetic compatibility (EMC), ukufeza ukuguqulwa kwamandla ahlanzekile.
(6) Isixhumi esibonakalayo somsebenzisi. Ngokungeziwe kumenyu yokudonsela phansi evamile, iphaneli yokusebenza yesiguquli sefrikhwensi entsha iphinde inikeze imisebenzi yokuqapha nokusebenza njengamathuluzi ezithombe namamenyu wesiShayina.
(7) Izinyathelo eziqondisiwe zokususa iphutha. Uhlobo olusha lwesiguquli semvamisa lunomhlahlandlela wangaphakathi wokulungisa amaphutha futhi luqondisa izinyathelo zokususa iphutha zesisebenzisi, ngaphandle kwesidingo sokubamba ngekhanda amapharamitha, okubonisa ngokugcwele ukusebenza kwawo kalula. Ngokuthuthukiswa kobuchwepheshe bokuguqula imvamisa, ukuzilungisa kwamapharamitha okuguqula imvamisa kuzoba okusebenzayo.
(8) Igrafu yethrendi yepharamitha. Ishadi lepharamitha lethrendi lesiguquli sefrikhwensi entsha lingabonisa isimo sokusebenza sesikhathi sangempela, futhi imingcele yokusebenza ingaqashelwa futhi irekhodwe noma kunini phakathi nenqubo yokulungisa iphutha.
2. Ukuqondiswa kwentuthuko yesikhathi esizayo yeziguquli zemvamisa
(l) Yenza ngcono ithiyori yokulawula futhi uthuthukise amasu okulawula. Nakuba ukulawulwa kwe-vector nokulawulwa kwetorque eqondile kuye kwathuthukisa kakhulu ukusebenza kwezinhlelo zokulawula isivinini se-AC, zisekhona izindawo eziningi ezidinga olunye ucwaningo. Ubuchwepheshe bokulawula ikusasa labaguquli bemvamisa buzothuthukiswa ngokuqhubekayo ngesisekelo esikhona, kufaka phakathi imodeli yereferensi yobuchwepheshe obuguquguqukayo obususelwa kuthiyori yokulawula yesimanje, ubuchwepheshe bokulawula obuguquguqukayo obuguquguqukayo, ubuchwepheshe bokulawula obulungile, ukulawulwa okungaqondakali okusekelwe kubuchwepheshe bokulawula obuhlakaniphile, amanethiwekhi we-neural, izinhlelo zochwepheshe, inqubo yokuzithuthukisa, ubuchwepheshe bokuzibona iphutha, njll., okwenza iziguquli zemvamisa zibe "zingenangqondo" futhi kulula ukuzisebenzisa.
(2) Ukulawulwa kwedijithali ngokugcwele ngesivinini esiphezulu. Ngokusetshenziswa kwezilawuli zedijithali ezisuselwe kuma-microprocessors angu-32-bit anesivinini esikhulu, ubuchwepheshe obusha bokusebenzisa idivayisi ye-elekthronikhi yamandla, izinhlelo zokusebenza zeWindows, isofthiwe ehlukahlukene ye-CAD, nesofthiwe yezokuxhumana yethulwe kubuchwepheshe bokulawula isiguquli semvamisa, okuvumela ama-algorithms okulawula ahlukahlukene, ukusetha ipharamitha, imisebenzi yokulawula eklanywe ngokukhululekile, amasu wokuhlela okuyingcaca, nobunye ubuchwepheshe bokulawula idijithali okufanele bufezeke.
(3) Ubuchwepheshe bokusetshenziswa kwamandla amasha kagesi. Ngokuthuthukiswa kwamadivayisi amasha okushintsha amandla, cisha ubuchwepheshe be-drive, ubuchwepheshe obubili be-PWM inverter, ubuchwepheshe be-PWM obuguquguqukayo, ubuchwepheshe bokulawula okuzenzakalelayo kwedijithali ngokugcwele, ubuchwepheshe bokwabelana bamanje obuqinile futhi obuguquguqukayo be-Surge absorption technology, ukulawulwa kokukhanya kanye nobuchwepheshe bokucupha i-electromagnetic, kanye ne-conductivity eshisayo kanye nobuchwepheshe bokukhipha ukushisa kuzothuthukiswa ngokushesha.
(4) Umthamo omkhulu kanye nevolumu encane yeziguquli zemvamisa. Ngokuthuthukiswa kwemishini ye-elekthronikhi yamandla amasha, ukusetshenziswa kwamamojula wamandla ahlakaniphile wezingane kanye nomthamo okhulayo kanye nevolumu encane yeziguquli zefrikhwensi kuzobonakala kancane kancane.
(5) Okuningi ngokuhambisana nezidingo zokuvikelwa kwemvelo, ukuba 'umkhiqizo oluhlaza' wangempela. Ubuchwepheshe bokuhambisana kwe-electromagnetic bokuguqula imvamisa buthola ukunakwa okukhulayo. Ngesisekelo sokuxazulula umsindo we-low-frequency converter frequency converters, abantu bahlola izixazululo zemisebe kagesi kanye nezinkinga zokungcoliswa kwe-harmonic zama-converter frequency, futhi bathole imiphumela emihle. Ngikholwa ukuthi esikhathini esizayo esiseduze, iziguquli zemvamisa "zomkhiqizo oluhlaza" zizokhonjiswa kubantu.
(6) Umsebenzi wesiguquli sefrikhwensi esimesha idivayisi yempendulo yamandla ukuguqula amandla emishini (amandla angenzeka, amandla e-kinetic) emthwalweni onyakazayo abe amandla kagesi (amandla kagesi avuselelwe) ngokusebenzisa idivayisi yempendulo yamandla bese uyithumela emuva kugridi yamandla e-AC ukuze isetshenziswe ezinye izisetshenziswa zikagesi eziseduze, ukuze uhlelo lokushayela imoto lukwazi ukunciphisa ukusetshenziswa kwamandla kagesi wegridi ngesikhathi seyunithi eyodwa, ngaleyo ndlela kuzuze umgomo wamandla.
