Eli nqaku likuthatha nzulu kule mida mithathu, lityhila ikamva letekhnoloji ye-transformer.

Isahluko Sokuqala: IiTransformers zeSolid-State—Ukusuka kwi "Iron Mass" ukuya kwi "Power Router"

1.1 Isiphelo sabaGuquli beSiqhelo

Iitransformer eziqhelekileyo zintle kwaye zincinci.

Zintle ngokulula kwazo: i-iron core kunye nee-coils ze-copper, i-electromagnetic induction, akukho zinto zihambayo, zithembekile kangangeminyaka emininzi. Zilinganiselwe kolo lula lufanayo: zinokuguqula i-voltage kuphela ngokungashukumiyo. Azikwazi ukulawula ukuhamba kwamandla, azikwazi ukulungisa ii-waveforms, azikwazi ukulawula ukuhamba kwe-bidirectional, azikwazi ukudibana ngqo ne-DC.

Kwixesha leegridi zendlela enye kunye nemithwalo ezinzileyo, le mida yayingabalulekanga. Kodwa igridi yanamhlanje yahlukile ngokupheleleyo—amandla elanga nawomoya ayatshintshatshintsha kakhulu, izithuthi zombane zitshaja ngendlela engalindelekanga, amaziko edatha afuna uzinzo olugqithisileyo, kwaye icala lokuhamba kwamandla alisalungiseki. Indlela engasebenziyo yeetransformer zesiqhelo iya isiba nzima ngakumbi.

1.2 IiTransformers zeSolid-State: Ukuchaza ngokutsha ukuba yintoni iTransformer

Ii-Solid-state transformers (ii-SST) zitshintsha ngokupheleleyo umdlalo.

Umgaqo wabo wokusebenza wahluke ngokupheleleyo kwiitransformer zesiqhelo: okokuqala, ukulungisa i-AC engenayo ukuya kwi-DC; emva koko kusetyenziswa izixhobo ze-elektroniki zamandla ukuguqula i-DC ibe yi-AC ephindaphindayo (amawaka ukuya kumakhulu amawaka e-hertz); ukudlula kwitransformer encinci ephindaphindayo; kwaye ekugqibeleni ukulungisa okanye ukuguqula kwakhona kwisiphumo esifunekayo.

I-frequency ephezulu yeyona nto ibalulekileyo. Ubungakanani be-transformer buhambelana ngokuphambeneyo ne-frequency yokusebenza—i-frequency ephezulu ithetha i-core encinci. I-transformer efuna amakhulu eekhilogram ze-iron core kwi-50 Hz inokufuna kuphela i-magnetic core enobukhulu besundu kwi-kilohertz eziliqela. Leyo yimfihlo engasemva kwamandla e-SST okwenzanciphisa ubungakanani ukuya kuthi ga kwi-90%xa kuthelekiswa noyilo oluqhelekileyo.
