Isingeniso Seshaja

Amashaja (amashaja) angahlukaniswa abe yimishini yefrikhwensi yezimboni kanye nemishini yemvamisa ephezulu ngokuya ngokusebenza kwesekethe yokuklama. Imishini yemvamisa yezimboni iklanywe ngokususelwa kuzimiso zesekethe ye-analog evamile. Amadivayisi angaphakathi kwamandla omshini (njengama-transformer, ama-inductors, ama-capacitor, njll.) makhulu uma kuqhathaniswa. Ngokuvamile, kunomsindo omncane lapho ugijima ngomthwalo omkhulu, kodwa le modeli inokumelana okunamandla ezimweni zemvelo zegridi yamandla aqinile, futhi ukwethembeka nokuzinza kwayo kunamandla kunemishini yefrikhwensi ephezulu.

Imishini yemvamisa ephezulu isebenzisa ama-microprocessors (ama-CPU chips) njengezikhungo zokucubungula nokulawula, futhi ishisa amasekhethi e-analog ehadiwe eyinkimbinkimbi ibe ama-microprocessors ukulawula ukusebenza kwe-UPS ngendlela yezinhlelo zesofthiwe. Usayizi wehliswa kakhulu, isisindo sincishiswa kakhulu, izindleko zokukhiqiza ziphansi, futhi intengo yokuthengisa iphansi kakhulu. Imvamisa ye-inverter yemishini yohlobo oluphezulu ngokuvamile ingaphezulu kuka-20KHZ. Kodwa-ke, imishini yemvamisa ephezulu ayibekezeleli kahle ngaphansi kwegridi yamandla aqinile nezimo zemvelo, futhi ifaneleka kakhulu ezindaweni ezinamagridi kagesi azinzile, uthuli oluncane, kanye nezinga lokushisa/umswakama ofanele.

Uma kuqhathaniswa namashaja emvamisa yezimboni, amashaja emvamisa ephezulu mancane ngosayizi, alula ngesisindo, aphakeme ngokusebenza kahle (izindleko eziphansi zokusebenza), umsindo uphansi, afanele izindawo zamahhovisi, abiza-okusebenza kahle (intengo ephansi ngamandla afanayo), futhi anomthelela omncane esikhaleni nasendaweni ezungezile. Uma kuqhathaniswa, amashaja efrikhwensi ephezulu asengozini yokuba nomthelela (SPIKE) kanye nempendulo yesikhashana (TRANSIENT) ebangelwa amakhophi, amaphrinta e-laser namamotho. Njengoba i-transformer yeshaja yamafrikhwensi embonini ihlukanisa amapayipi amakhulu kumthwalo, ishaja yefrikhwensi yemboni inganikeza ukuvikeleka okuphephile nokwethenjelwa kakhulu kuneshaja yefrikhwensi ephezulu endaweni enzima yamapayipi amakhulu. Kwezinye izimo ezifana nokwelashwa, ishaja idingeka ukuthi ibe nedivayisi yokuhlukanisa. Okwezimboni, ezokwelashwa, ezokuthutha nezinye izinhlelo zokusebenza, ishaja yefrikhwensi yezimboni iyinketho engcono. Ukukhetha phakathi kwalokhu kokubili kufanele kukalwe ngokuvumelana namakhasimende ahlukene, indawo yokufaka, izimo zomthwalo kanye nezinye izimo.
