Achitaurazve Power Supply - akavimbika mudziviriri zvemagetsi

Chero yemagetsi midziyo inoda kushandiswa simba zvokuyamura. Chokwadi kuti romugove voltage iri kazhinji haana kufanana chii chinodiwa kuti vakawanda mano, havazombonyanyi vanofanira nechokwadi mberi uye risina kumiswa simba zvitengeswa. Too yakaderera kana mukuru voltage akasvetuka nekukurumidza goho kune zvakarukwa chero midziyo kukundikana. The dambudziko iri rakawanikwa refu - ndiko kushandisa simba nerubatsiro kuti inodzora voltage uye chinodzivirira mudziyo.

Nhasi kushandisa Linear uye nokuchinja simba zvitengeswa. First ndakagamuchira kupararira nekuda kwavo nyore, kukurumidza kuita chero mutoro shanduko uye isimbe. Asi pane zvainovhiringidzawo: yakaderera kunyatsoshanda, bulkiness pamusoro transformer, kuti aikanganiswa mazano voltage nokupisa nounzenza. Nezvikonzero izvi, Linear simba rinopiwa zvishoma nezvishoma kuitwa ne kupomba, vane unongotaura vanganzi nani.

Munguva yedu, pane miniaturization ari midziyo, saka transformer simba wedzerai redunhu anogona kutowanikwa yechinyakare. Achitaurazve simba zvitengeswa ane kuwanda zvakanaka, pakati inomira akabudisa ichitenderera zvinhu nemari, uye zvinoderedza iyi mari mudziyo pacharo, akashambidzika kukura, kuvimbika, yakafara uchishandisa siyana. Unhu izvi hazvigoni kufuratirwa nokuda redhiyo amateurs uye nyanzvi. Zvisinei, pane drawback: kunyange nyore chinja muoti simba nerubatsiro ane wemaoresa vanoronga vaungane uye akamisa, asi chokwadi ichi haagumiri vanatenzi chaidzo.

Ups kunyange anodhura pane kwakajairika zvinogumbura, asi havana chete vakawana uye wokutepfenyurisa wedzerai voltage, asi zvinonzi kudzikamiswa nokudzivirira roga uye siyana nzendo dambudziko. Zvinonzi zvino kushandiswa chaizvo nokuchinja simba wedzerai imwe Audio kakawanda gudzazwi, microcontroller anotsanangura mano, uye kushandisa michina zvinoreva kuti mumwe midziyo yakasiyana-siyana. Pakutanga, vakanga akashandiswa materevhizheni uye siyana Video michina.

Achitaurazve simba zvitengeswa akatotanga akasimbisa pacharo sezvo mari, hwakavimbika uye nyore kushandisa mudziyo mumwe. Zvino vagadziri zviri kuita nadzurudzo aripo yokutevedzera tichitarisa miniaturization yacho chinhu chawo, uye kuvandudza rakavimbika mudziyo.

Kune vazhinji Ups zvirongwa, asi vanoshanda panenge pane ichocho. Single bara jenareta anodyisa kare kunogadzirisika mains voltage, mumwe kupomba transformer pamwe yechipiri mutoro uri rectifier, uye kubva ipapo vanopiwa ne vatengi. Zvichienderana womuenzaniso, iyo jenareta anogona kuva kwokunze kana kuzvipira pokutangira. transistor jenareta unoshanda nokuchinja muoti. Kana kuvharwa, vose simba unopinda mutoro, uye kana akazarurwa - mu kupomba transformer zvakachengetwa simba.

Achitaurazve simba zvitengeswa nechokumusoro uye vatendeuki zvemagetsi simba kubva AC samambure kuti simba rinodiwa kuti simba midziyo yakasiyana-siyana. Uchishandisa voltage AC, zvisina akakodzera mano mazhinji uye kuderedza kushandiswa kwavo nguva. Simba romugove chikwata inodzivirira zvokushandisa, vachipfuura chinogamuchirika chete voltage pasina kuenda mhiri miganhu.
