I-Solid State High Frequecy Working Principle

Okubizwa ngokuthi "i-solid state high frequency" yingoba isebenzisa ama-transistors(MOS field effect transistors noma IGBT)njengezingxenye ze-inverter eziyinhloko.Ngokungafani namashubhu e-vacuum angenalutho(ingaphakathi ligcwele igesi ehloniphekile, ngakho-ke lingabizwa ngokuthi "igesi"),ama-transistors aqinile.

I-Solid state high frequency iwumkhiqizo obuyekeziwe we-vacuum tube frequency high, futhi umjikelezo wayo oyinhloko ufana ne-thyristor medium frequency, kodwa uhlukile ku-vacuum tube frequency high. Umgomo wayo oyisisekelo umi kanje: 

I-AC yezigaba ezintathu ezijwayelekile (i-380V kanye ne-frequency 50HZ e-China) iguqulelwa ku-voltage eguquguqukayo i-pulsating DC ngokusebenzisa i-rectifying circuit(SCR noma i-diode kanye ne-IGBT), le DC iyahlungwa noma i-flat wave ibe yi-DC eshelelayo, bese ingena ebhulohweni eliguquguqukayo (lisebenzisa i-transistor yamandla amakhulu i-MOSFET noma i-IGBT) ukuze ibe yamanje yamafrikhwensi aphezulu. Lesi sakamuva se-high frequency current sinikezwa ku-tank circuit load resonance singasetshenziselwa ukushisa kwensimbi.Amayunithi wamandla ebhuloho le-Inverter amukela isakhiwo se-modular.amamojula wamandla wepheya ngalinye ayafana.kodwa inani lamamojula wamandla asetshenziswayo liyahlukahluka kuye ngamandla wemishini.Kungakhathaliseki ukuthi okokusebenza kukhulu noma kuncane, isakhiwo ngokuyisisekelo siyafana.Isifunda se-resonant tank sisechungechungeni noma i-voltage ephezulu yesimo esihambisanayo futhi ayikho ifomu lokukhipha amandla.

Uma kuqhathaniswa namashubhu evacuum aphezulu, izinzuzo zemishini yemvamisa ephezulu zimi kanje:

1.Ikhwalithi enhle yokushisela: ukuqhathanisa kukhombisa ukuthi amapayipi ensimbi ashiselwe imishini yefrikhwensi ephezulu anobubanzi obuhlanganisiwe nokushisa, kanye nama-burrs ambalwa angaphakathi nangaphandle.

2.Ukonga amandla:ukuhlola kukhombisa ukuthi ukucaciswa okufanayo kwesishiseli kungonga ugesi ongaphezu kwama-25% uma kuqhathaniswa nemishini yeshubhu ye-vacuum

3.Ukonga amanzi:ngenxa yokulahlekelwa okuncane.akudingi amanzi amaningi okupholisa.ngakho kusebenzisa amanzi angaphansi kuka-50% kunemishini ye-vacuum tube enemininingwane efanayo.

4.Usayizi omncane nesisindo esilula:ngenxa yobukhulu obuncane bezingxenye eziyinhloko(MOSFET) futhi azikho izilawuli ze-welding transformer.filament.matching coils.gate circuits.etc. Ngakho ivolumu iyonke ingaphezu kuka-50°/4. incane kunemishini yeshubhu ye-vacuum yokucaciswa okufanayo

5.Kulula ukusebenza: ayikho i-voltage, i-voltage ephezulu ingeqi ama-volts angamakhulu ambalwa, ngakho-ke ngeke kubangele ukulimala komuntu
