Itekhnoloji yokugunyazisa ye izixhobo zokufudumeza ezikwi-frequency ephezulu

Ukugunyaziswa kwe izixhobo zokufudumeza ezikwi-frequency ephezulu

Yesiqhelo kufuneka ibe yesiqhelo phambi kokusetyenziswa.Jonga i-inverter ngokulandela la manyathelo alandelayo:

① vala kuphela unikezelo lwamandla kwindawo yolawulo (qaphela: musa ukuvala iswitshi enkulu yomoya wesekethe enkulu), cofa umnyango wekhabhathi.

Iqhosha lokuqala eliguquliweyo (iqhosha eliluhlaza), lungisa iqhosha lohlengahlengiso lwamandla ngasekunene ukuya kwindawo ephezulu, kwaye ujonge nge-oscilloscope yemigca emibini ukuba isiginali yedrive kwipali yolawulo yemodyuli nganye ye-IGBT iqhelekile (i-pulse imalunga ne-50% yesikwere wave, ububanzi be-pulse

Umphezulu umalunga ne + 15V, ikhefu limalunga ne-8V. Imigca enyukayo nehlayo ingaphakathi kwe-1 μS, kunye nengalo yebhulorho ibe mbini phezulu naphantsi.

Ummandla ofileyo we-IGBT gate pulses mkhulu kune-2 Μs) kwaye uqinisekisa ukuba i-IGBT yesiginali ye-drive yengalo yebhulorho efanayo i-isophase (iimpazamo eziphezulu kunye nezantsi mazingabi ngaphezu kwe-0.5 Μs) kunye ne-IGBT ye-drive signal ye-high and low. iingalo zebhulorho kufuneka zibuyiselwe umva.

Ukuhlolwa kwe-② yokuhlaziya i-pulse.Cofa iqhosha lokuqala, amasango amathathu e-SCR kufuneka abe ne-pulse ene-amplitude enkulu kune-1.8V, ububanzi be-pulse kunye ne-pulse frequency malunga ne-10kHz.

③ Uvavanyo lokumelana noxinzelelo. Vala isekethe enkulu yokutshintsha umoya (musa ukuvala iswitshi yolawulo lombane) Ngeli xesha, jonga i-DC voltmeter pointer inyuka kancinci ukuya ngaphezulu kwe-500V, jonga ukuba isixhobo siqhelekile (akukho sandi esingaqhelekanga, Akukho vumba, kwaye akukho kuphazamiseka kwesixhobo), gcina ngasekunene kangangemizuzu eli-10, kuxhomekeke kwisixhobo esiqhelekileyo, isitshixo samandla esiphambili sinokucinywa.

Uxinzelelo ngokuzenzekelayo luyehla luye kwiqanda.

④ izixhobo zokufudumeza eziphakamileyo, landela la manyathelo alandelayo ukuqalisa i-inverter.

Qhagamshela amanzi okupholisa kwaye ujonge ukuba ijelo ngalinye lamanzi okupholisa liqhelekile na. Lungisa i-counterclockwise yeqhosha lohlengahlengiso lwamandla kwindawo ephantsi, vala iswitsha yempompo, iswitsha yokulawula amandla kunye nokutshintsha kwamandla amakhulu, Qaphela xa i-DC voltmeter iphakama ukuya phantse kwi-500V nge Ukutshaja Cinezela iqhosha lokuqalisa ukulibazisa imizuzwana emi-2 kwi-inverter elungileyo Itafile nganye iya kuba nemiyalelo ehambelana nayo, ngokuthe ngcembe yonyuse uhlengahlengiso lweqhina lewotshi, kwaye imiyalelo ye-DC yangoku kunye nemitha yamandla iya kunyuka kwangoko kwaye ifikelele kwixabiso elinikiweyo. ngoku ekusebenzeni okuqhelekileyo.Abasebenzi abathunyelwe ngumvelisi wezixhobo ukuba balungise ixabiso lokumisela ukhuseleko kwixabiso elifunekayo (isixhobo silungelelaniswe ngokusisiseko ngaphambi kokushiya umzi-mveliso, kwaye sinokuhlengahlengiswa ngokufanelekileyo ngokwendawo).

Inkcazelo ye ⑤ motherboard potentiometer

P1—— ishunisela ihuku yendlela yamaza yangoku ephakathi kufutshane nesine iliza kwaye ishiye malunga nee-engile ezingama-200.

I-P2—— ilungelelanisa ubungakanani bexesha eliphakathi lokuthintela ubungakanani bexabiso.

I-P3— FM yangoku yamkela ubungakanani bexabiso.

I-P8—— ilungelelanisa ubungakanani bexabiso lokhuselo lwangoku.

I-P9— I-FM yangoku ubungakanani bexabiso lokukhusela.

P10—— Ulungelelwaniso lweTheyibhile yeFrekhwensi.

Shuswa kula manyathelo alandelayo.

Kuqala lungisa iqhosha lohlengahlengiso lwamandla ngokunxamnye newotshi kwisikhundla esisezantsi, cinezela iqhosha lokumisa umva, kwaye umise isandi esiphakathi rhoqo ngokukhawuleza.Cima iswitsha yamandla engundoqo, jonga i-DC voltage meter yehla ukuya kwi-zero, uze ucime isitshixo sonikezelo lwamandla olawulo. kunye nempompo yamanzi

Tshintsha.

Inkcazo yesibane somqondiso wepaneli yolawulo ephambili ye-⑦ izixhobo zokufudumeza ezikwi-frequency ephezulu:

Inkcazo ye-⑧ yesibane somqondiso wepaneli yokhuseleko lwangaphandle:

⑨ isilumkiso: Emva kokuba umbane oyintloko uvaliwe okanye uguqulwe, awuvunyelwe ukuvavanya nayiphi na inxalenye nge-oscilloscope okanye itafile, ngaphandle koko ukungaphumeleli kuya kwenzeka ngenxa yokufikelela kwiiparamitha ngaphandle kokuphela kovavanyo lwesixhobo.
