Nekukurumidza kusimudzira kwemagetsi emagetsi tekinoroji uye tekinoroji yekudzora komputa, shanduko yetekinoroji yemagetsi drive yakasimudzirwa.Ac kumhanya kudzora panzvimbo yeDC kumhanya kudzora, komputa yedhijitari yekudzora pachinzvimbo cheanalog kutonga yave maitiro ekusimudzira.Ac motor frequency conversion speed regulation ndiyo nzira huru yekuchengetedza simba, kunatsiridza maitiro ekugadzira, kugadzirisa mhando yechigadzirwa, uye kugadzirisa nharaunda yekushandisa.Variable frequency speed regulationnekuita kwayo kwepamusoro, simba repamusoro, pamwe nekumhanyisa kudzora uye kuita mabhureki uye nezvimwe zvakawanda zvakanaka zvinoonekwa seanovimbisa zvakanyanya kumhanya mutemo.
The yapfuurahigh-voltage inverter, inoumbwa ne thyristor rectifier, thyristor inverter uye mamwe madivayiri, ine zvikanganiso zvakawanda, huru harmonics, uye ine simba pane gidhi remagetsi uye motokari.Mumakore achangopfuura, mamwe maturusi matsva akagadzirwa achachinja mamiriro ezvinhu aya, akadai IGBT, IGCT, SGCT uye zvichingodaro.Iyo yakakwira voltage inverter inoumbwa navo ine mashandiro akanaka uye inogona kuona PWM inverter uye kunyange PWM kugadzirisa.Kwete chete ma harmonics madiki, asiwo iyo simba chinhu chinovandudzwa zvakanyanya
Ac frequency conversion speed regulation tekinoroji isanganiswa yemagetsi akasimba uye asina simba, michina uye yemagetsi yekubatanidza tekinoroji, kwete chete kubata nekushandurwa kwesimba rakakura (kugadzirisa, inverter), asiwo kubata nekuunganidzwa kweruzivo, shanduko uye kutapurirana. , saka inofanira kukamurwa kuva simba uye kutonga zvikamu zviviri.Iyo yekutanga inofanirwa kugadzirisa matambudziko ehunyanzvi ane chekuita neakakwira voltage uye yakakwira ikozvino, uye iyo yekupedzisira inofanirwa kugadzirisa software uye matambudziko ekudzora hardware.Naizvozvo, remangwana repamusoro-voltage frequency shanduko yekumhanyisa regulation tekinoroji ichagadziridzwawo mune izvi zviviri zvinhu, kuita kwayo kukuru ndekwe:
(1) Thehigh voltage variable frequencyichavandudza munzira yesimba repamusoro, miniaturization uye kureruka.
(2) Thehighvoltage variable frequency driveichakura mumativi maviri: yakananga mudziyo yakakwira voltage uye yakawanda superposition (mudziyo wakatevedzana uye unit unit).
(3) Midziyo mitsva yemagetsi semiconductor ine yakakwira voltage uye yakakwira ikozvino ichaiswa mukatihigh voltage variable frequency drive
(3) Panguva ino, IGBT, IGCT, SGCT icharamba ichiita basa guru, SCR, GTO ichabuda mumusika we inverter.
(4) Iko kushandiswa kwevector control, flux control uye yakananga torque control tekinoroji isina kumhanya sensor inokura.
(5) Ziva zvizere digitaalinen uye otomatiki: parameter self-setting tekinoroji;Process self-optimization tekinoroji;Kutadza kuzviongorora tekinoroji.
(6) Iko kushandiswa kwe32-bit MCU, DSP uye ASIC zvishandiso, kuti uwane yakakwirira chaiyo uye yakawanda-inoshanda inverter.
(7) Maindasitiri anotsigira ane hukama ari kuenda kuhunyanzvi uye budiriro huru, uye kupatsanurwa kwevashandi kuchave pachena.
