Kuti uone kushanduka kwekumhanya kwemota, inverter tekinoroji inoshandiswa zvakanyanya mukuputika-proof mota.Semudziyo, iyo inverter inogona kushandura magetsi emagetsi emagetsi (50Hz kana 60Hz) kuita akasiyana frequency AC magetsi ekupa, kuitira kuti uwane iyo inoshanduka yekumhanyisa kushanda kwemota.Chigadzirwa chacho chinosanganisira dunhu rekutonga rekutonga guru guru;Rectifier circuit yekushandura alternating current kuti itungamirire ikozvino;Iyo DC yepakati redunhu inoshandiswa kutsvedzerera uye kusefa inobuda yeinogadzirisa rekiti;Inverter redunhu, rinoshandiswa kushandura yakananga ikozvino kuita alternating ikozvino.Mune mamwe ma frequency converter ayo anoda kuita akawanda ma operation, zvakare zvinodiwa kuve neCPU yekuverengera torque uye inoenderana nedunhu.Nekushandura magetsi ekupa frequency ye stator winding yemotor, variable frequency speed regulation inogona kuona chinangwa chekudzora kumhanya.
Inverter Zvinoenderana neyakasiyana nzira dzekuisa, inogona kukamurwa kuita voltage rudzi inverter uye yazvino mhando inverter, PAM control inverter, PWM control inverter uye yakakwira carrier frequency PWM control inverter, V / f control inverter, slip frequency control inverter uye vector control inverter, General inverter, high performance yakakosha inverter, high frequency inverter, single phase inverter uye matatu phase inverter, nezvimwe.
Mune frequency converter, VVVF inoreva kushandura voltage uye frequency, ukuwo CVCF ichireva inogara voltage uye inogara frequency.Mumagetsi eAC anoshandiswa munyika dzepasirese, mungave mudzimba kana mafekitori, voltage uye frequency zvinowanzoita 400V/50Hz kana 200V/60Hz(50Hz).Chishandiso chinoshandura magetsi akadaro kuita voltage kana frequency variable AC magetsi anodaidzwa kuti "frequency converter".Kuti ugadzire mavhiriji anosiyana uye ma frequency, chishandiso chekutanga chinoda kushandura alternating ikozvino kunanga ikozvino (DC).
Iyo frequency converter inoshandiswa kudzora mota uye inogona kushandura zvese voltage uye frequency.Zvinoenderana nekumhanya kwekutaura kweiyo AC mota, kumhanya n inoenderana nefrequency f, uye kumhanya kwemota kunogona kugadziridzwa chero frequency f yashandurwa.Naizvozvo, iyo frequency converter inoona yekumhanyisa mutemo nekushandura mota magetsi emagetsi frequency, inova yakanyanya kunyatsoshanda uye yakakwira performance performance regulation zvinoreva.
Mukuvandudzwa kwema frequency converters, nzira dzakasiyana dzekudzora dzakashanduka, kusanganisira:
Sinusoidal pulse width modulation (SPWM) control mode, apo 1U/f=C;
Voltage space vector (SVPWM) control mode;
Vector control (VC) maitiro;
Yakananga torque control (DTC) maitiro;
Matrix intersection - intersection control mode, nezvimwe.
Pamusoro, iyo innovative application ye inverter mukuputika-proof mota inotsanangurwa.Kuburikidza neinverter tekinoroji, kumhanya kwemota kunogona kuchinjika, kuunza kushanda kwepamusoro uye yakakwirira kuita kwemagetsi mhinduro kumunda weindasitiri.
