Kuti uwane kuita kwakaringana kwebhenji remagetsi magetsi, zvakakosha kuti unzwisise misimboti yayo. Simba rebhenji remagetsi rinoshandura simba rekupinza reAC kubva kumadziro kuita DC simba rinoshandiswa kusimbisa zvinhu zvakasiyana mukati mekombuta. Inowanzo shanda pane imwe-chikamu AC yekupinda uye inopa akawanda DC inobuda voltages, senge +12V, -12V, +5V, uye +3.3V.
Kushandura iyo AC yekupinza simba kuita DC simba, bhenji remagetsi rinoshandisa shanduko kushandura yakakwira voltage uye yakaderera ikozvino AC yekupinza simba kuita yakaderera voltage uye yakakwirira ikozvino AC chiratidzo. Iyi AC siginecha inozogadziriswa pachishandiswa diode, iyo inoshandura iyo AC chiratidzo kuita pulsating DC voltage.
Kuti unyorovedze iyo pulsating DC voltage, desktop power supply inoshandisa macapacitor anochengeta yakawandisa charge uye nekuiburitsa panguva ye low voltage, zvichikonzera kugadzikana kwakanyanya DC inobuda voltage. Iyo DC voltage inozodzorwa ichishandisa voltage regulator dunhu kuti ive nechokwadi chekuti inoramba iri mukati mekushivirira kwakasimba, kudzivirira kukuvadzwa kwezvikamu. Dziviriro dzakasiyana-siyana, senge overvoltage dziviriro, overcurrent dziviriro, uye pfupi dunhu redziviriro, zvakare yakavakirwa mumadesktop emagetsi ekudzivirira kukuvadzwa kwezvikamu kana paine kukanganisa.
Kunzwisisa misimboti yemagetsi edesktop kunogona kubatsira mukusarudza akakodzera magetsi eiyo komputa system uye kuona kushanda kwakakwana.
Muchinyorwa chino, isu tichavhara izvo zvekutanga kuti chii chinonzi benchtop magetsi, mashandisiro aungaita nemazvo, uye chii chekutarisa pakusarudza modhi.
Chii chinonzi Benchtop Power Supply?
Paunenge uchishanda purojekiti inoda huwandu chaihwo hwemagetsi eDC, magetsi ebhenji anogona kuuya anoshanda. Chaizvoizvo idiki simba rekupa rakagadzirirwa kugara pabhenji rako rebasa.
Midziyo iyi inozivikanwawo semagetsi e lab, magetsi eDC, uye magetsi anogoneka. Iwo akakwana kune zvemagetsi kune avo vanoda kuwana yakavimbika uye nyore-kushandisa-simba sosi.
Nepo kune akati wandei emhando dzemagetsi ebhenji dziripo-kusanganisira dzine mabasa ekutaurirana, marudzi akawanda anobuda, uye dzine akasiyana siyana-dzose dzakagadzirirwa kuita kuti mashandiro ako ave nyore uye nemazvo.
Inoshanda sei?
A benchtop power supply chinhu chinosiyana-siyana chemidziyo inopa simba rakadzorwa kumidziyo yemagetsi. Inoshanda nekudhirowa tambo yemagetsi eAC kubva kune mains uye nekuisefa kuti ipe inogarobuda DC. Maitiro acho anosanganisira akati wandei, anosanganisira transformer, rectifier, capacitor, uye voltage regulator.
Semuyenzaniso, mune mutsara wemagetsi emagetsi, transformer inodzika pasi voltage kusvika padanho rinogoneka, rectifier inoshandura iyo AC ikozvino kuDC, iyo capacitor inosefa kunze chero ruzha rwakasara, uye voltage regulator inovimbisa yakagadzikana kubuda kweDC. Nekugona kugadzirisa voltage uye mazinga azvino uye kudzivirira zvishandiso kubva pamusoro pesimba, bhenji remagetsi chishandiso chakakosha cheotomatiki yekuongorora masisitimu, Chikoro chekudzidzisa rubatsiro, nezvimwe.
Nei zvichikosha?
Simba remagetsi rebhenji rinogona kunge risiri iro rinonyanya kunaka chidimbu chemidziyo mulabhu yeinjiniya yemagetsi, asi kukosha kwayo hakugone kuwedzeredzwa. Pasina imwe, kuyedzwa uye prototyping hazvigoneke pakutanga.
Benchtop magetsi ekupa inopa yakavimbika uye yakagadzikana sosi yevoltage yekuyedza uye kusimbisa magetsi maseketi. Vanobvumira mainjiniya kusiyanisa voltage uye zvazvino kune zvikamu zvekuyedza miganhu, tarisa maitiro avanoita mumashandisirwo akasiyana, uye ive nechokwadi chekuti achashanda nemazvo muchigadzirwa chekupedzisira.
Kuisa mari mubhenji remagetsi emhando yepamusoro kungasaite sekunge kuri kutenga kwakanyanya. Zvakadaro, inogona kuita zvakakosha pakubudirira uye kugona kwemagetsi dhizaini nekusimudzira.
