Main Circuit
Lub ntsiab Circuit Court yog lub zog hloov dua siab tshiab seem uas muab qhov sib txawv voltage thiab zaus zog rau lub asynchronous lub cev muaj zog. Lub ntsiab Circuit Court ntawm ib zaus converter tuaj yeem muab faib ua ob pawg: voltage- hom converters, uas hloov DC los ntawm qhov hluav taws xob mus rau AC, thiab nws cov DC circuit filtering siv capacitors; thiab tam sim no - hom converters, uas hloov DC los ntawm qhov tam sim no mus rau hauv AC, thiab nws DC circuit filtering siv inductors. Nws muaj peb ntu: "rectifier" uas hloov lub zog hluav taws xob rau hauv DC lub zog, "smoothing circuit" uas absorbs voltage pulsations generated hauv converter thiab inverter, thiab "inverter" uas converts DC zog rau hauv AC zog.
Rectifier
Diode converters tau dav siv, hloov lub zog loj rau hauv DC lub zog. Ib tug reversible converter kuj yuav tsim siv ob pawg ntawm transistor converters; vim nws cov kev taw qhia fais fab rov qab, rov ua haujlwm yog ua tau.
Smoothing Circuit Court
Lub DC voltage rectified los ntawm lub rectifier muaj ib tug pulsating voltage ntawm rau lub sij hawm lub hwj chim mov zaus. Tsis tas li ntawd, lub pulsating tam sim no tsim los ntawm inverter kuj ua rau DC voltage hloov pauv. Txhawm rau tiv thaiv kev hloov pauv voltage, inductors thiab capacitors yog siv los nqus cov pulsating voltage (tam sim no). Rau cov khoom siv muaj peev xwm me me, yog tias muaj cov npoo txaus hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tseem ceeb, cov inductor tuaj yeem raug tshem tawm, ua rau lub voj voog yooj yim dua.
Inverter
Conversely rau lub rectifier, lub inverter converts DC hwj chim rau hauv AC zog ntawm qhov yuav tsum tau zaus. Los ntawm kev hloov rau 6 lub tshuab hloov pauv ntawm lub sijhawm tau teem tseg, 3-theem AC tso zis tuaj yeem tau txais. Lub sij hawm hloov thiab qhov hluav taws xob waveform yog qhia siv lub zog-hom PWM inverter ua piv txwv.
Lub Circuit Court tswj yog lub Circuit Court uas muab kev tswj cov teeb liab rau lub ntsiab Circuit Court uas muab lub zog (adjustable voltage thiab zaus) rau lub asynchronous lub cev muaj zog. Nws muaj "kev ntsuas hluav taws xob" rau qhov zaus thiab qhov hluav taws xob, "voltage thiab tam sim no nrhiav tau hluav taws xob" rau lub ntsiab Circuit Court, "ceev nrhiav kom tau qhov hluav taws xob" rau lub cev muaj zog, "tsav Circuit Court" uas nthuav tawm cov teeb liab tswj los ntawm kev suav Circuit Court, thiab "tiv thaiv circuits" rau lub inverter thiab lub cev muaj zog.
Kev ntsuas hluav taws xob: Sib piv cov kev ceev sab nraud thiab lub zog torque nrog cov teeb liab tam sim no thiab qhov hluav taws xob los ntawm kev kuaj xyuas Circuit Court los txiav txim qhov tso zis voltage thiab zaus ntawm inverter.
Voltage thiab tam sim no nrhiav tau Circuit Court: Tshawb xyuas qhov hluav taws xob thiab tam sim no, cais tawm ntawm lub peev xwm loj hauv Circuit Court.
Tsav Circuit Court: Circuit Court uas tsav lub ntsiab Circuit Court Cheebtsam. Nws yog cais los ntawm cov tswj Circuit Court thiab tswj lub switching on thiab off ntawm lub ntsiab Circuit Court Cheebtsam.
Kev ntsuas ceev Circuit Court: Lub teeb liab los ntawm lub ntsuas ntsuas ceev (TG, PLG, thiab lwm yam) ntsia ntawm lub asynchronous lub cev muaj zog ncej yog siv los ua lub teeb liab ceev thiab pub rau hauv lub voj voog tswj. Raws li cov lus qhia thiab kev suav, lub cev muaj zog tuaj yeem ua haujlwm ntawm qhov ceev ceev.
Kev tiv thaiv Circuit Court: Nws pom qhov voltage thiab tam sim no ntawm lub ntsiab Circuit Court. Thaum muaj qhov txawv txav xws li overload lossis overvoltage tshwm sim, nws tiv thaiv kev puas tsuaj rau lub inverter thiab asynchronous lub cev muaj zog.
