Ukuqhathanisa ugesi ojwayelekile we-KGPS ophakathi nendawo, amandla kagesi aphakathi kwe-IGBT kanye nogesi omusha onga ugesi we-KGPSSD ophakathi nendawo

1. Ukunikezwa kwamandla okujwayelekile kwe-KGPS SCR parallel IF

Izinzuzo yilezi: ibisetshenziswa kakhulu emashumini ambalwa eminyaka edlule, intengo ephansi, ukugcinwa okulula, kanye nezinsiza ezishibhile.

Ububi buwukuthi: ukusetshenziswa kwamandla aphezulu, ukusetshenziswa kukagesi ngethani ngalinye lensimbi encibilikisiwe kungaphezu kwama-700 degrees. Amandla alungiswa ngokulungisa i-voltage ye-DC, isici samandla siphansi (≤0.85), futhi kukhona ukuphazamiseka kwe-harmonic, okunamazinga ahlukahlukene omthelela ekusebenzeni kwe-capacitor yesinxephezelo samandla asebenzayo esiteshini.

2. Ukunikezwa kwamandla okuvama okumaphakathi kwe-IGBT

Izinzuzo yilezi: ukulungiswa kusebenzisa ukulungiswa kwegagasi eligcwele, futhi indlela yokuhlunga ye-LC eyakhiwe ngama-capacitor nama-inductors yenza isici samandla sifinyelele ngaphezu kwe-0.96, ngokuyisisekelo ngaphandle kokuphazanyiswa kwe-harmonic. Ingxenye ye-inverter ithatha imodi yokusebenza ye-inverter yochungechunge, futhi umthwalo usebenza ngaphansi kwesimo se-voltage ephezulu kanye namanje ephansi, futhi ukulahlekelwa kwethusi kuncane, okuthuthukisa kakhulu ukusebenza kahle. Ukusetshenziswa kukagesi ngethani ngalinye lensimbi encibilikisiwe kungaphansi kwama-degree angu-600.

Ububi buwukuthi: Ukunikezwa kwamandla okuvama okumaphakathi kwe-IGBT kudinga indawo yokusebenza ephezulu.

3. Uchungechunge olusha lokonga amandla lwe-KGPSSD thyristor ukunikezwa kwamandla okuphakathi nendawo

I-KGPSSD i-thyristor ye-thyristor yamandla amaphakathi aphakathi nendawo izuza izinzuzo zemikhiqizo emibili engenhla, isebenzisa amandla okulungisa amagagasi agcwele, futhi isilungisisi sihlala sisesimweni sokusebenza ngokugcwele (okulingana nokulungiswa kwe-diode) phakathi nayo yonke inqubo yokusebenza; isici samandla esisetshenziswa sihlala sisezingeni eliphezulu kakhulu (≧0.96) . Ayikhiqizi ama-harmonics e-oda eliphezulu, ayinakho ukungcola kugridi yamandla, futhi ayiphazamisi ukusebenza kwama-capacitor esinxephezelo samandla asebenzayo esiteshi esincane. Uma kuqhathaniswa namandla ajwayelekile e-thyristor parallel intermediate frequency, yonga cishe u-15%. Ngaphezu kwalokho, izingxenye zishibhile, kulula ukuzithenga futhi kulula ukuzilungisa.
