Ngenxa yokuthi i-inverter isebenzisa amazinga kagesi ahlukene wokunikezwa kwamandla, kuyadingeka ukunikeza amazinga ahlukene we-voltage lapho ugcina i-inverter.Kodwa-ke, ugesi wangempela wesigaba sesithathu esingu-200v AC noma i-voltage yesigaba sesithathu engu-400v AC ayidingeki ekulungisweni kwezinga lebhodi noma ngisho nokugcinwa kwezinga le-chip (ngaphandle kwalokho, uma uthumela umthwalo).Okudingekayo i-voltage engu-200v kanye ne-400v AC kanye ne-voltage engu-300v kanye ne-500v DC ehambisanayo.Nakuba kunezinhlobo eziningi zamandla kagesi e-DC alungisekayo emakethe, ayabiza futhi umsebenzi wokuvikela awulungile.Eminyakeni eminingi yomsebenzi wokulungisa, umbhali wenze ugesi okhethekile wokulungisa izinga le-inverter chip ngakho kokubili ukuphuma kwamandla kagesi we-AC kanye ne-DC kanye nemisebenzi ephelele yokuvikela.
Indlela yokukhiqiza I ye-inverter yokulungiswa kwamandla kagesi:
Umthethosivivinywa Wezinto Zokusebenza:
1 AC othintana naye 220V 32A Ubuningi: 2
2 I-Transformer 220V ukuya ku-380V 500W Isigaba Esisodwa Ubuningi: 1
3 Inombolo yezinkinobho zokuzivala (indawo SB SB1) 2
4 Imodeli yebhuloho le-Rectifier MDQ100A Ubuningi: 1
5 I-resistor yokushaja (isikhundla RL) 120W60R Ubuningi: 1
6 I-Electrolytic capacitor (isikhundla C1 C2 C3 C4) 400V680UF Ubuningi: 4
7. I-Voltage equalizing resistor (indawo RC1 RC2 RC3 RC4), resistor 2W180k, ubuningi 4
8 DC voltmeter, DC1000V uhlobo lwesikhombi
9 I-resistor yokukhipha (isikhundla RB) 120W60R Ubuningi: 1
Imidwebo:
Indlela II yokwenza ugesi wokulungisa inverter:
Ezinye izitolo zokulungisa izinto, ezinqunyelwe izimo, azinawo amandla okulungisa izigaba ezintathu, okuletha ukuphazamiseka ekugcinweni kwama-inverter, ikakhulukazi i-AC kanye ne-DC voltage regulators (iziqalisi ezithambile) nezinye izinto zikagesi.
Ngemuva kokuhlolwa okuningana kanye nokwenza kahle kwesakhiwo, ugesi wesigaba sesithathu we-inverter wenziwa futhi i-waveform yokuphumayo yahlolwa.Sawubona!I-waveform enhle, iseduze kakhulu nokunikezwa kwamandla.
Njengoba kuboniswe emfanekisweni:
Uma isiguquli sefrikhwensi esinogesi ongu-380V wezigaba ezintathu sihlanganiswa, isifunda sokushaja sokulibaziseka kwe-KT1 sizokwengezwa, futhi amapharamitha aso angafana nalawo esekethe yangaphakathi yokushaja.I-isolation transformer yamukela isilinganiso soguquko esingu-1:1;Uma isiguquli esinamandla okokufaka angu-220V sisetshenziswa, isixhumanisi somkhawulo samanje se-KT1 singashiywa, futhi i-220:380 i-step-up transformer isetshenziswa njengesiguquli sokuhlukanisa.Uma i-R2=R1 ikhethiwe, umthamo wokuxhumana we-KT1 kufanele ube mkhulu kuno-5A.Uma inganele, kufanele kwengezwe i-relay.
Njengoba kudingekile, i-T1T2 ingafaniswa ngokuya ngokuphumayo kwamanje kwesiguquli semvamisa.Ngisebenzisa i-inverter yesandla sesibili, i-isolation transformer kanye ne-reactor engasebenzi futhi kulula ukuyithola.
Uma kunesidingo, isekethe yesihlungi sokulungisa kabusha ingangezwa esigabeni sakamuva ukuze kutholwe ugesi olungisekayo we-DC ongu-0~550V.Lapho i-waveform yokuphumayo ingalungile, zama ukulungisa imvamisa yenkampani yenethiwekhi yesiguquli ukuze ivumelane nesikhathi sokuhlunga se-LC esingaguquki, ukuze uthole ukuphuma kwe-waveform okungcono.
