Amashaja (amashaja) ahlukaniswe ngokulandela imvamisa yokusebenza kwesekethe yokuklama, engahlukaniswa ngemishini yokuvama amandla kanye nemishini yokuvama okuphezulu.Imishini yefrikhwensi yamandla iklanywe ngokusekelwe ezimisweni zesekethe ye-analog evamile.Amadivayisi wamandla angaphakathi (njengama-transformer, ama-inductors, ama-capacitor, njll.) ) Makhulu ngokuqhathaniswa, ngokuvamile kuba nomsindo omncane lapho egijima ngomthwalo omkhulu, kodwa le modeli inokumelana okuqinile nokumelana nezimo ezinzima zemvelo yegridi, nokuthembeka kwayo. futhi ukuzinza kunamandla kunemishini yama-high-frequency.
Umshini osebenzisa imvamisa ephezulu usebenzisa i-microprocessor (CPU chip) njengesikhungo sokulawula ukucutshungulwa, futhi ushisa amasekhethi e-analog yehadiwe eyinkimbinkimbi ku-microprocessor ukuze ulawule ukusebenza kwe-UPS ngohlelo lwesofthiwe.Ngakho-ke, umthamo uyancipha kakhulu.Isisindo sincishiswa kakhulu, izindleko zokukhiqiza ziphansi, futhi intengo yokuthengisa iphansi kakhulu.Imvamisa ye-inverter yomshini we-high-frequency ngokuvamile ingaphezulu kuka-20KHZ.Kodwa-ke, umshini we-high-frequency unokubekezelelana okungalungile ngaphansi kwegridi yamandla enamandla kanye nezimo zemvelo, ezifaneleka kakhulu ukuzinza kwegridi nothuli.Imvelo enezinga lokushisa eliphansi kanye nomswakama.
Uma kuqhathaniswa nemishini ye-high-frequency: imishini ye-high-frequency kanye ne-micro-frequency: usayizi omncane, isisindo esincane, ukusebenza kahle okuphezulu (izindleko zokusebenza eziphansi), umsindo ophansi, ofanele izindawo zehhovisi, ukusebenza kwezindleko eziphezulu (intengo ephansi ngamandla afanayo) , umthelela esikhaleni nasendaweni ezungezile Okuncane, uma kuqhathaniswa, umthelela (SPIKE) kanye nokusabela kwesikhashana (TRANSIENT) okubangelwa amashaja amaza kakhulu kumakhophi, amaphrinta e-laser, namamotho kuthinteka kalula.
Ezimweni ezinzima, imishini yefrikhwensi yamandla inganikeza ukuvikeleka okuvikeleke kakhulu futhi okuthembekile kunemishini yefrikhwensi ephezulu. Kwezinye izikhathi njengokwelashwa, kuyadingeka ukuthi ishaja ibe nedivayisi yokuhlukanisa.Ngakho-ke, ezimbonini, ezokwelapha, ezokuthutha kanye nezinye izinhlelo zokusebenza, imishini yefrikhwensi yamandla iyisinqumo esingcono.Ukukhethwa kokubili kufanele kucatshangelwe ngokuvumelana namakhasimende ahlukene, indawo yokufaka, izimo zomthwalo kanye nezinye izimo.
Izici zomshini wefrikhwensi yamandla zilula, futhi izinkinga yilezi:
1. Ubukhulu be-input kanye ne-output transformer bukhulu;
2. Ubukhulu besihlungi esiphumayo esisetshenziselwa ukuqeda ama-harmonics aphezulu bukhulu;
3. I-Transformer ne-inductor idala umsindo womsindo;
4. Ukusebenza kwempendulo eguquguqukayo ukulayisha kanye nezinguquko zamandla amapayipi kubi.
5. Ukusebenza kahle okuphansi;
6. Okokufaka akunakho ukulungiswa kwesici samandla, okubangela ukungcoliswa okukhulu kwegridi yamandla;
7. izindleko eziphezulu, ikakhulukazi kumamodeli wamandla amancane, azikwazi ukuqhathaniswa nemishini ye-high-frequency.
