I-inverter yochwepheshe idala amathuba angapheli.

Isingeniso seI-Inverter

I-inverter iyisisetshenziswa se-elekthronikhi esiguqula i-alternating current ibe yamanje eqondile, ikakhulukazi esetshenziselwa ukunikeza amandla emthwalweni.I-Inverter iyithuluzi eliguqula umthombo kagesi we-DC ube umthombo wamandla kagesi we-AC.Ingasetshenziswa ku-microcomputer noma ohlelweni lwe-single-chip microcomputer kanye namathuluzi okucubungula amasignali.

Iziguquliingahlukaniswa ngama-inverters esigaba esisodwa, isigaba sesithathu kanye ne-full-bridge ngokusho kwezinga lamandla.Ama-inverters esigaba esisodwa kanye nesigaba sesithathu akhiwe ngama-transformers, izihlungi nezihlungi ze-LC, futhi i-waveform yokuphumayo i-sine wave;ama-inverters ebhuloho eligcwele akhiwe isekethe yesihlungi esilungisa kabusha, isekethe ye-Schottky diode (PWM) kanye nesekethe yedrayivu, futhi i-waveform yokuphumayo iyigagasi lesikwele.

Iziguqulizingahlukaniswa zibe izinhlobo ezintathu: uhlobo olumisiwe lokuvala, uhlobo lokulawula indawo efile (umzila wegagasi elinesine) nohlobo lokulawula lokushintsha (umzila wegagasi lesikwele).Ngokuthuthukiswa kobuchwepheshe bamandla kagesi, ama-inverters asetshenziswa kabanzi emikhakheni ehlukahlukene.

Imiqondo eyisisekelo

I-inverter iyisisetshenziswa se-elekthronikhi samandla esiguqula i-direct current ibe yamanje eshintshanayo.I-inverter iqukethe isekethe yesihlungi esilungisa kabusha, isekethe ye-Schottky diode (SOK) kanye nesekethe yedrayivu.

I-inverter ingahlukaniswa ibe i-inverter esebenzayo kanye ne-passive inverter, i-passive inverter, eyaziwa nangokuthi i-inverter circuit noma i-voltage regulator circuit, ngokuvamile ngesiteji sokufaka, isihlungi sesiteji esimaphakathi (LC), isigaba sokuphuma (rectifier), njll., I-inverter esebenzayo iwukuguqulwa kwesiginali ye-voltage yokufaka ukuze kutholwe i-DC voltage ezinzile.

I-inverter ye-passive ngokuvamile ine-capacitor yesinxephezelo ebhulohweni lokulungisa, kuyilapho i-inverter esebenzayo ine-inductor yesihlungi ebhulohweni lokulungisa.

I-inverter circuit inezinzuzo zobukhulu obuncane, isisindo esincane, ukusebenza kahle okuphezulu nokunye.Iyingxenye ebalulekile yazo zonke izinhlobo zamathuluzi kagesi kagesi.

Ukwahlukanisa

Ngokusho kwe-topology ye-inverter ingahlukaniswa: i-inverter egcwele ibhuloho, i-push-pull inverter.

Ingahlukaniswa nge-PWM (i-pulse wide modulation) inverter, SPWM (quadrature signal modulation) inverter kanye ne-SVPWM (i-space voltage vector modulation) inverter.

Ngokwesigaba sesifunda sokushayela singahlukaniswa: i-half-bridge, push-pull type.

Ngokusho kohlobo lokulayisha, ingahlukaniswa ibe yi-single-phase inverter power supply, izigaba ezintathu ze-inverter power supply, i-DC converter, i-inverter esebenzayo yesihlungi samandla, njll.

Ngokusho kwemodi yokulawula ingahlukaniswa: Imodi yamanje kanye nemodi ye-voltage.

Inkambu yohlelo lokusebenza

Ama-inverters asetshenziswa kakhulu ku-automation yezimboni, imishini yezempi, i-aerospace neminye imikhakha.Isibonelo, ekuzishintsheni kwezimboni, amadivayisi esinxephezelo samandla asebenzayo ikakhulukazi asetshenziswa ezinhlelweni zamandla angalungisa ukuphakelwa kwamandla kagesi aphezulu, athuthukise ukusebenza kahle kokukhiqiza, onge amandla kagesi futhi anikeze ukuhlinzekwa kwamandla okuzinzile okukhiqizwa kwezimboni;ekuxhumaneni, imishini yesinxephezelo samandla asebenzayo ingasetshenziswa ukulungisa ugesi wesistimu ye-low-voltage ukuze uzinzise phakathi kwebanga elifanele futhi uthole ukuxhumana okude;kwezokuthutha, zingasetshenziswa ohlelweni lokuqala lwenjini yemoto kanye nohlelo lokushaja ibhethri lemoto;emishinini yezempi, ingasetshenziswa ekunikezeni amandla kanye nohlelo lokulawula okuzenzakalelayo lwemishini yezikhali;emkhathini, angasetshenziswa enjinini yendiza eqala ukunikezwa kwamandla kanye nokushaja kwebhethri amandla.
