Introduce
Ordinary voltage regulator power supply iri kuburikidza nesampling circuit kudzora pa/kudzima kwesimba remagetsi regulator chubhu kushandura kupikisa kwemukati kwemagetsi kuitira kuti voltage pamutoro igadzikane.
Kuchinja kwemagetsi regulator magetsi kuri kuburikidza nekutonga kwechikamu chechubhu yekubatidza nekudzima kuti ugadzirise kubuda kwemagetsi.
Zvakanakira
Zvakanakira zvekuchinja voltage regulator magetsi.
Advantages 1: kushandiswa kwesimba kwakaderera, kushanda kwakanyanya, compact uye kureruka
Kubatsira kwayo kukuru ndiko kushanda kwepamusoro.Mumamiriro ekuchinja, iyo transistor pachayo inoshandisa shoma basa, uye inoshandura regulator pachayo inogona kusvika makumi manomwe kusvika makumi masere muzana ekubudirira, asi isingadi danho-pasi-shanduko.Yayo inobuda transformer inoshanda pamhepo huru uye nehuwandu husingasviki 50 Hz muIF transformer.Dunhu reiyo switching regulator, saka, ine mukana wakawedzerwa wekuva diki uye uremu.Inogona kushanda pane yakakura voltage renji.
Advantage 2: Yakasiyana-siyana yemagetsi regulation
Iyo voltage inobuda kubva kune switching regulator inodzorwa neiyo basa kutenderera kwechiratidzo chekusimudzira, uye shanduko mumagetsi ekuisa chiratidzo inogona kubhadharwa ne frequency modulation kana kuwedzera.Nenzira iyi, kana iri shanduko huru mune frequency grid voltage, inogona kuramba ichive yakagadzikana yakawedzera kubuda voltage.Pakazere, huwandu hwemagetsi emagetsi ekuchinja akafara kwazvo uye voltage yekudzikamisa mhedzisiro yakanaka.
Zvakanakira 3: Flexible mafomu edunhu
Semuenzaniso, kune kuzvifadza uye zvimwe-zvinofadza, zvakafara-siyana uye frequency-regulated, single-end uye kaviri-kuguma, nezvimwewo.Vagadziri vemagetsi ekugadzira magetsi vanogona kushandisa zvakanakira emhando dzakasiyana dzemaseketi kugadzira nekuvandudza ma switching voltage regulators anogona kusangana nemashandisirwo akasiyana.
Basa
Kubva pakugadzirwa kwemagetsi kusvika nhasi, kushandiswa kwemagetsi kunogona kutaurwa nekuvandudzwa kwevanhu, hupenyu hwevanhu hwakaunza kufambira mberi uye nyore.Asi zvinotiunzira nyore panguva imwe chete, asiwo zvinotiunzira matambudziko akawanda.Mukugadzira kwedu rarama, isu tinowanzo kusangana nekusagadzikana kwemagetsi, kunyanya pakati pemutsara, uye panguva yepamusoro penguva yemagetsi.Munharaunda iri kuwedzera yakakwirira-chaizvo, kana magetsi asina kugadzikana, zvinounza kusagadzikana kukuru kuhupenyu hwedu hwekugadzira.Imwe nzira chete yekushandura dunhu kana kushandura nzvimbo ndeyekumisa chishandiso chemagetsi chekubatsira.Uye maererano nemagetsi ekubatsira midziyo ine chekuita, iyo isingadhure uye yakapusa michina ndeye voltage regulator.
Mumazuva ekutanga, basa guru remagetsi regulator raiva rekugadzirisa magetsi.Iyo regulator inogona kusimudza voltage pakaitika kusagadzikana kwemagetsi, kana pakaitika yakaderera voltage, kuve nechokwadi chekuti mudziyo unogona kushanda zvakajairwa.Nekudaro, nekuvandudzwa kwetekinoroji, pamwe nevanhu vari kuwedzera zvakanyanya zvinodiwa zvemidziyo.Nhasi voltage regulators, kwete chete kuvimbisa kuti voltage yakajairika, asi zvakare inovimbisa kuchengetedzwa kwekushanda kwemagetsi.Naizvozvo, pamusoro pekuve nechokwadi chekushanda kwakajairwa kwemidziyo, iyo voltage regulator zvakare ine pfupi dunhu redziviriro, pfupi chikamu chekudzivirira, uye mamwe akawanda mabasa ekudzivirira.
Main Parameters
Iwo makuru ma paramita eiyo DC voltage regulator.
DC inodzorwa magetsi emagetsi (voltage regulator) yeakanyanya tekinoroji paramita anogona kukamurwa kuita mapoka maviri: imwe ndiyo yemhando zviratidzo, ichiratidza kunaka kweDC voltage kudzikamisa magetsi.Inosanganisira kugadzikana, yakaenzana yemukati kuramba (output resistance), ripple voltage, uye tembiricha coefficient.Chimwe chikamu indekisi yehunhu, inoratidza hunhu hweiyo DC-inodzorwa magetsi ekupa.Semuyenzaniso, yekupinda DC yakadzora magetsi ekupa magetsi, inobuda voltage, inobuda ikozvino, uye yakabuda voltage regulation regu.
1, voltage regulation rate SV
Voltage regulation rate chiratidzo chakakosha kuratidza kushanda kweDC voltage kudzikamisa magetsi, inozivikanwawo seyo kudzikamisa chinhu kana kugadzikana chinhu.Iyo inoratidzirwa kana iyo yekuisa voltage VI inochinja kana iyo DC voltage kudzikamisa magetsi emagetsi kubuda voltage VO kugadzikana, kazhinji inoratidzirwa sechikamu chepakati chekuchinja kweyekupinza uye kubuda vhoriyamu pachikamu chekubuda kwemagetsi.
2, ikozvino kugadzirisa chiyero SI
Ikozvino chiyero chekutonga chiratidzo chikuru chekuremerwa kweiyo DC voltage stabilizer, inozivikanwawo seyazvino kugadzikana chinhu.Inotaridzwa kana magetsi ekuisa anoramba asina kuchinjika, DC voltage kudzikamisa magetsi nekuda kwekuchinja kwemutoro wazvino (output current), uye kubuda kwevoltage kukonzeresa kunokonzerwa nekudzvanyirira simba, pasi pemamiriro emutoro wakatarwa kuchinja kwazvino, kazhinji kuratidzwa. sechikamu cheshanduko yemagetsi ekubuda payuniti inobuda voltage ikozvino regulation mwero weDC voltage kudzikamisa magetsi.
3,Rpple kurambwa ratio SR
Iyo ripple rejection rejection inoratidza iyo DC voltage regulator padivi rekupinza rekutanga kweiyo mains voltage rejection kugona, kana iyo DC voltage regulator yekupinda uye inobuda DC voltage regulator zvikamu zvinoramba zvisina kuchinjika, iyo ripple yekuramba reshiyo inowanzo ratidzwa maererano nekupinza ripple. voltage peak-to-peak uye inobuda ripple voltage peak-to-peak ratio, inowanzo ratidzwa mumadecibel, asi dzimwe nguva inogona kuratidzwa sechikamu, kana zvakananga nereshiyo yevaviri vakati.
4, Kugadzikana kwekushisa K
Kugadzikana kwekushisa kweiyo yakasanganiswa DC magetsi emagetsi anotsanangurwa muDC magetsi ekushandisa tembiricha Ti yakakwira huwandu hwekuchinja (Tmin ≤ Ti ≤ Tmax) DC magetsi emagetsi emagetsi emagetsi anoenderana shanduko muhuwandu hwehuwandu.
Nezve Zvigadzirwa
Iyo LM9036 yekupedzisira-yakaderera quiescent ikozvino regulator inoratidzira yakaderera yekudonha voltage uye yakaderera ikozvino mune yekumira modhi.Iine isingasviki 25µA Ground Pin ikozvino pane 0.1mA mutoro, iyo LM9036 yakanyatsokodzera mota uye mamwe mabhatiri masisitimu anoshanda.Iyo LM9036 inochengeta ese maficha akajairwa kune yakaderera dropout regulators zvinosanganisira yakaderera dropout PNP pass mudziyo, pfupi dunhu dziviriro, reverse kuchengetedza bhatiri, uye kupisa kudzima.Iyo LM9036 ine 40V yakakura yekushandisa voltage limit, a -40 ° C kusvika + 125 ° C yekushanda tembiricha renji, uye ± 5% inobuda voltage kushivirira pamusoro pese kuburitsa ikozvino, kupinza voltage, uye tembiricha renji.
