Amandla kagesi - izinhlobo zayo kanye nokusetshenziswa

Enye yezinkinga eziyinhloko ezibhekene kokubili abathanda abanolwazi futhi imfundamakhwela ukuklama amadivayisi kagesi kanye umsakazo, amandla. Ukuze izidingo idatha futhi ithuthukiswe ezifana umthombo wamandla (SP) idivayisi.

Lapho ekhetha thuluzi kufanele inake ezicini eziningana ezibalulekile, okuyinto kunqunywa izimo zokusebenza, izidingo zokuphepha, properties kanye imithwalo ezinye izinto. Ngaphezu kwalokho, isidingo acabangele izinhlobo amadivaysi ezinjalo, ezifana supply amapayipi - kungaba namandla, amandla aphakathi nendawo noma micropower.

Ngokuyinhloko udinga ukuba banake ukuhambisana kwemigomo izidingo kudivayisi zedivayisi sikagesi. Okuphakela amandla has inombolo ethile izici ezifanayo ukuhlela: ukusetshenziswa wamanje, voltage, amandla adingekayo (evamile noma ngokulinganisa) ezingeni ekulinganiseni voltage, ezivunyelwe (futhi ubuncane bayo kanye seqiwe), ezingeni voltage yezwakala.

Futhi, amandla supply has ezinye izimfanelo nezici kungithinte ukusebenza kwawo futhi ububanzi. Ngokwesibonelo, ukuba khona noma ukungabi khona isivikelo, isisindo nobukhulu balezi idivayisi.

Amandla kagesi - iyingxenye ebalulekile kunoma iyiphi idivayisi ye-elekthronikhi. Kusho kokubili amandla aphansi nezamabanga aphakeme ukunikezela kufanele nakanjani ibe naso ukuze ihambisane nezidingo ezisebenza ngokunabileko imishini futhi izingxenye zalo ingxenye. Uma idivayisi ezifana emthombeni wamandla, okunye okukhethwa kukho kokushaya kuyofika ingafinyeleleki, kungaholela nokungezwani e umkhiqizo futhi umonakalo zayo.

Kukhona ukubukwa eziningana imithombo yenethiwekhi amandla:

- ne epholisayo, noma Damping Resistor (okuthiwa transformerless);

- yomugqa, okuyinto ahlelwe ngokuvumelana isikimu classical (rectifier transformator-, kulandele filtration futhi sinjalo);

- ephezulu voltage high-imvamisa ishayela;

- yesibili ishayela (transformer wesifunda ukusebenza amaza okusezingeni eliphezulu Izihlungi - Converter);

- yama yodwa ugesi;

- komugqa FE.

Ukuthuthukiswa iyona elula kunazo futhi ifinyeleleke hobbyists. Avame elisetshenziswa kumadivayisi amancane naphakathi, ezifana amashaja, amabhethri, amandla ompompi, mkhosi, nokunye. Futhi lapha akunakubangelwa umthombo ungaphazanyiswa ugesi (UPS).

Nokho, lapho usebenzisa amagugu samanje ezingaphezu kweyodwa ampere, ukuphumelela leli thuluzi, njengoba komugqa okuphakela amandla ngokucijile kwehle ngo yezizathu ezihlukahlukene:

- sinjalo isici iyoba engazinzile ngenxa oscillations we amapayipi voltage;

- imisinga okusezingeni eliphezulu okudinga ukufakwa heatsinks enkulu olawula transistors futhi ekulungiseni diode;

- sikokufaka isimame siyokondliwa ngokucace kakhudlwana voltage ephakeme kunanoma iyiphi elivumelekile ekushintshashintsheni inethiwekhi.

Nokho, muva nje, sekuyinto evamile ngempela ishayela converters (zesibili), kanye umthombo wamandla ngesisekelo ephezulu imvamisa transducers nge transformerless okokufaka.
