Ukuhlaziywa Kwe-Parallel Resonant Inverter Yokunikezwa kwamandla Okumaphakathi Okumaphakathi
Ukuhlaziywa kwe-Parallel Resonant Inverter ye Ukunikezwa kwamandla okuvama okumaphakathi
I-inverter ye-resonant ehambisanayo, umthwalo wayo ufana nomthwalo we-resonant. Ngokuvamile umthombo wamanje uyadingeka ukuze unikeze amandla. Ekushisiseni kokungeniswa, umthombo wamanje uvame ukwakhiwa isilungisisi kanye ne-inductor enkulu. Ngenxa yenani elikhulu le-inductance, kungalinganiselwa ukuthi okwamanje ekugcineni kwe-inverter kulungisiwe. Ukuvula nokuvala ngokunye ukuvala amadivaysi alawulekayo ku-inverter kungathola igagasi lesikwele elishintshanayo lamanje ekuphumeni kwe-inverter. I-amplitude yamanje incike kunani lamanje lokokufaka kwe-inverter, futhi imvamisa incike kudivayisi. imvamisa yokusebenza. Njengoba kuboniswe kuMfanekiso 2.4, i-inverter exhuma i-capacitor yesinxephezelo kanye nekhoyili yomthwalo (L no-R) ngokuhambisana njengomthwalo webhuloho lokuguqula ubizwa ngokuthi i-parallel resonant inverter. I-inductance Ld enkulu ixhunywe ochungechungeni ne-DC power supply inverter parallel, ngakho-ke umthwalo wamanje uhlala njalo futhi awuthinteki ngokushintsha komthwalo we-impedance. Uma isici samandla okulayisha kungesona esingu-1, ingxenye ye-voltage esebenzayo yomthwalo izongezwa kudivayisi yokushintsha. Ukuze uvimbele i-IGBT ukuthi ingalinyazwa i-voltage ehlehlayo, i-diode esheshayo kufanele ixhunywe ochungechungeni ne-IGBT. Ngisho noma kusetshenziswa imojula ye-IGBT, ngoba kukhona i-anti-parallel diode esheshayo ngaphakathi, i-IGBT ngeke imelane ne-voltage ehlehlayo, futhi i-diode esheshayo yochungechunge ayikwazi ukukhanselwa, ngaphandle kwalokho idivayisi izolimazwa amandla ajikelezayo okubangelwa amandla ayo. i-voltage ehlehlayo. Ngokobudlelwano besigaba sikagesi kanye nesigaba samanje sesekethe yethangi lomthwalo, inverter efanayo ingase isebenze ezifundeni ezintathu zokusebenza: i-resonance, inductive kanye ne-capacitive states. Ngenxa yobukhona be-inductance enkulu Ld, ukuze kugcinwe okuqhubekayo okuqhubekayo, ngesikhathi senqubo yokuguqulwa, amabhuloho aphezulu naphansi Ingalo ye-IGBT kufanele ilandele isimiso sokuqala ukuvula bese ivala, okungukuthi, kufanele kube khona ukugqagqana isikhathi RT. Ubude besikhathi sokugqagqana sokushintsha buhlobene eduze ne-inverter ye-wiring inductance. I-inductance inkulu, isikhathi eside..
