Uhlalutyo lweParallel Resonant Inverter ye UBonelelo lwaMandla oMbane waMazinge aPhakathi

I-inverter ye-resonant ehambelanayo, umthwalo wayo ngumthwalo ohambelanayo. Ngokuqhelekileyo umthombo wangoku uyafuneka ukunika amandla. Ekufudumeni kwe-induction, umthombo wangoku uhlala uqulunqwe ngumlungisi kunye ne-inductor enkulu. Ngenxa yexabiso elikhulu le-inductance, linokuqikelelwa ukuba i-current in the input end of inverter is fixed. Ngolunye uhlobo ukukhanyisa kunye nokucima izixhobo ezilawulwayo kwi-inverter kunokufumana i-square wave wave ngoku kwimveliso ye-inverter. I-amplitude yangoku ixhomekeke kwixabiso langoku legalelo le-inverter, kwaye i-frequency ixhomekeke kwisixhobo. ukusebenza rhoqo. Njengoko kuboniswe kuMzobo 2.4, i-inverter edibanisa i-capacitor yembuyekezo kunye ne-coil yomthwalo (L kunye no-R) ngokufana nomthwalo webhuloho ye-inverter ibizwa ngokuba yi-parallel resonant inverter. I-inductance enkulu ye-Ld ixhunyiwe kwi-series kunye ne-DC power supply inverter parallel inverter, ngoko ke umthwalo wangoku uhlala uhleli kwaye awuchatshazelwa kukutshintsha komthwalo womthwalo. Xa umthamo wamandla omthwalo ungekho 1, icandelo lombane elisebenzayo lomthwalo liya kongezwa kwisixhobo sokutshintsha. Ukuze uthintele i-IGBT ukuba yonakaliswe yi-voltage ye-reverse, i-diode ekhawulezayo kufuneka idibaniswe kwichungechunge kunye ne-IGBT. Nokuba imodyuli ye-IGBT isetyenzisiwe, kuba kukho i-anti-parallel diode ekhawulezayo ngaphakathi, i-IGBT ayiyi kumelana ne-voltage eguqukayo, kwaye i-diode ekhawulezayo yochungechunge ayinakucinywa, ngaphandle koko isixhobo siya konakaliswa ngumbane ojikelezayo obangelwa yinkqubo yayo. umva wombane. Ngokwamandla ombane kunye nobudlelwane besigaba sangoku sesekethe yetanki yomthwalo, i-inverter ehambelanayo inokusebenza kumazwe amathathu asebenzayo: i-resonance, inductive kunye ne-capacitive state. Ngenxa yobukho be-inductance enkulu Ld, ukuze kugcinwe ukuqhubela phambili kwangoku, ngexesha lenkqubo yokuguqulwa, iibhulorho eziphezulu kunye nezisezantsi I-IGBT ingalo kufuneka ilandele umgaqo wokuqala wokuvula kwaye emva koko ucime, oko kukuthi, kufuneka kubekho ixesha elidityanisiweyo RT. Ubude bexesha lokutshintshwa kwe-overlap lihambelana ngokusondeleyo ne-inverter output wiring inductance. Inkulu inductance, ixesha elide..
