Analysis ntawm Parallel Resonant Inverter rau Intermediate zaus fais fab mov

Parallel resonant inverter, nws load yog parallel resonant load. Feem ntau yuav tsum muaj qhov chaw tam sim no los muab lub zog. Hauv induction cua sov, qhov tam sim no feem ntau yog tsim los ntawm lub rectifier thiab lub inductor loj. Vim yog tus nqi inductance loj, nws tuaj yeem kwv yees tias qhov tam sim no ntawm qhov kawg ntawm lub inverter yog tsau. Hloov pauv thiab tig tawm cov khoom siv tswj tau ntawm lub inverter tuaj yeem tau txais ib qho kev hloov square yoj tam sim no ntawm qhov tso tawm ntawm lub inverter. Lub amplitude ntawm qhov tam sim no nyob ntawm tus nqi tam sim no ntawm cov tswv yim ntawm lub inverter, thiab qhov zaus nyob ntawm lub cuab yeej. kev khiav hauj lwm zaus. Raws li pom nyob rau hauv daim duab 2.4, lub inverter uas txuas cov nyiaj capacitor thiab load coil (L thiab R) nyob rau hauv parallel raws li lub load ntawm lub inverter choj yog hu ua ib tug parallel resonant inverter. Ib tug loj inductance Ld txuas nrog series nrog DC fais fab mov nyob rau hauv parallel inverter, yog li cov load tam sim no tas li thiab tsis cuam tshuam los ntawm kev hloov ntawm load impedance. Thaum lub hwj chim load tsis yog 1, lub reactive voltage tivthaiv ntawm lub load yuav muab ntxiv rau lub switching ntaus ntawv. Txhawm rau tiv thaiv IGBT los ntawm kev puas tsuaj los ntawm qhov hluav taws xob rov qab, lub diode ceev yuav tsum tau txuas nrog cov IGBT. Txawm hais tias siv IGBT module, vim tias muaj kev tiv thaiv kev sib txuas ceev diode sab hauv, IGBT yuav tsis tuaj yeem tiv thaiv qhov rov qab voltage, thiab series ceev diode tsis tuaj yeem raug tshem tawm, txwv tsis pub lub cuab yeej yuav raug puas tsuaj los ntawm cov circulating tam sim no los ntawm nws. rov qab voltage. Raws li qhov voltage thiab tam sim no theem kev sib raug zoo ntawm lub load tank Circuit Court, lub parallel inverter yuav ua hauj lwm nyob rau hauv peb ua hauj lwm lub xeev: resonance, inductive thiab capacitive xeev. Vim muaj lub neej ntawm kev tsis sib xws loj LD, txhawm rau ua kom cov txheej txheem tam sim no, sab saud, sab saud thiab tom qab ntawd tig, uas yog, yuav tsum muaj sib tshooj RT. Qhov ntev ntawm lub sij hawm sib tshooj sib tshooj yog ze ze rau lub inverter tso zis thaiv inductance. Qhov loj dua qhov inductance, lub sijhawm ntev..
