Okwu mmalite nkeIhe ntụgharị
Ihe inverter bụ ngwaọrụ eletrọnịkị nke na-agbanwe mgbanwe nke ugbu a ka ọ bụrụ ugbu a na-aga kpọmkwem, nke a na-ejikarị enye ike n'ibu.Inverter bụ ngwaọrụ na-agbanwe isi iyi voltaji DC ka ọ bụrụ isi iyi voltaji AC.Enwere ike iji ya na microcomputer ma ọ bụ otu mgbawa microcomputer yana ngwa nhazi mgbaàmà.
Ndị ntụgharịnwere ike kewaa n'ime otu-phase, atọ-phase na full-akwa inverters dị ka ike larịị.Otu akụkụ na ndị inverters nke atọ mejupụtara ihe nzacha, ihe nzacha na ihe nzacha LC, na mmepụta waveform bụ sine ife;zuru-akwa inverters na-emi esịnede rectifier filter circuit, Schottky diode (PWM) sekit na mbanye sekit, na mmepụta waveform bụ square ife.
Ndị ntụgharịenwere ike kewaa ya n'ụdị atọ: ụdị akwụghị ụgwọ, ụdị njikwa mpaghara nwụrụ anwụ (ụzọ ikuku mmiri) na ụdị njikwa mgbanwe (ụzọ ebili mmiri square).Site na mmepe nke teknụzụ ọkụ eletrik, a na-eji inverters eme ihe n'ọtụtụ ebe.
Echiche ndị bụ isi
Ihe inverter bụ ngwaọrụ eletrọnịkị ike nke na-atụgharị ugbu a ka ọ bụrụ nke ọzọ.Ihe ntụgharị ahụ nwere sekit nzacha rectifier, sekit Schottky diode (SOK) na sekit mbanye.
Enwere ike kewaa inverter n'ime inverter na-arụ ọrụ na onye na-emegharị ihe, onye na-emegharị ihe, nke a makwaara dị ka sekit inverter ma ọ bụ voltaji regulator circuit, n'ozuzu site na ntinye ntinye, etiti etiti (LC), nzacha mmepụta (rectifier), wdg, na Inverter nọ n'ọrụ bụ ntụgharị mgbama voltaji ntinye iji nweta voltaji DC kwụsiri ike.
The passive inverter na-enwekarị ihe nkwụghachi ụgwọ capacitor na rectifier akwa, ebe ọrụ inverter nwere nzacha inductor na rectifier akwa.

Nhazi
Dị ka topology nke inverter nwere ike kewaa n'ime: zuru-akwa inverter, push-adọta inverter.
Enwere ike kewaa ya na PWM (modul obosara obosara) inverter, SPWM (modul quadrature signal modulation) inverter na SVPWM (space voltaji vector modulation) inverter.
Dị ka ịkwọ ụgbọala sekit nhazi ọkwa nwere ike kewaa: ọkara-akwa, push-adọta ụdị.
Dị ka ibu ụdị, ọ nwere ike kewaa n'ime otu-phase inverter ike ọkọnọ, atọ-phase inverter ike ọkọnọ, DC Ntụgharị, arụ ọrụ nzacha inverter ike ọkọnọ, wdg.
Dị ka njikwa mode nwere ike kewaa: ugbu a mode na voltaji mode.
