Nyocha nke Parallel Resonant Inverter maka Nnyenye ike ugboro ugboro

Parallel resonant inverter, ya ibu bụ yiri resonant ibu. A na-achọkarị isi iyi dị ugbu a iji nye ike. Na kpo oku induction, isi iyi dị ugbu a na-ejikarị ihe ndozi na nnukwu inductor. N’ihi nnukwu uru inductance, enwere ike ime ka ọ dị ugbu a na njedebe ntinye nke inverter. Ịgbanye ọzọ na ịgbanyụ ngwaọrụ ndị a na-achịkwa na inverter nwere ike nweta ihe ntụgharị ihu igwe dị ugbu a na mmepụta nke inverter. Njupụta nke ugbu a na-adabere na uru dị ugbu a nke ntinye nke inverter, na ugboro ole na-adabere na ngwaọrụ ahụ. ugboro ugboro. Dị ka e gosiri na Figure 2.4, inverter nke na-ejikọta capacitor nkwụghachi ụgwọ na eriri ibu (L na R) n’otu aka ahụ ka a na-akpọ ibu nke àkwà mmiri inverter a myirịta resonant inverter. A na-ejikọta nnukwu inductance Ld n’usoro na ọkụ ọkụ DC na ntụgharị ntụgharị, ya mere ibu dị ugbu a na-adịgide adịgide ma ọ dịghị emetụta mgbanwe nke impedance ibu. Mgbe ihe ike ibu na-abụghị 1, a ga-agbakwunye akụkụ voltaji reactive nke ibu ahụ na ngwaọrụ mgbanwe. Iji gbochie IGBT mebie site na voltaji ntụgharị, a ga-ejikọta diode ngwa ngwa n’usoro na IGBT. Ọbụlagodi na a na-eji modul IGBT eme ihe, n’ihi na enwere diode ngwa ngwa na-emegide ihe n’ime, IGBT agaghị anabata voltaji a na-atụgharị, na enweghị ike ịkagbu usoro diode ngwa ngwa, ma ọ bụghị ya, ngwaọrụ ahụ ga-emebi site na ikesa ugbu a kpatara ya. agbara voltaji. Dị ka voltaji na nke ugbu a na-adọ mmekọrịta nke ibu tank circuit, ndị yiri inverter nwere ike na-arụ ọrụ na atọ na-arụ ọrụ na-ekwu: resonance, inductive na capacitive steeti. N’ihi ịdị adị nke nnukwu inductance Ld, iji mee ka ihe na-aga n’ihu na-aga n’ihu, n’oge usoro mgbanwe ahụ, àkwà mmiri dị elu na nke dị n’okpuru ogwe aka IGBT ga-agbaso ụkpụrụ nke mbụ ịgbanwuo wee gbanyụọ, ya bụ, e kwesịrị inwe oge ndakọrịta RT. Ogologo oge nfegharị ahụ nwere njikọ chiri anya na inductance mmepụta wiring inverter. Ka inductance ka ukwuu, ka oge na-aga.
