Iimpawu zeMveliso

Ikhonkco lomqondiso kunye nolawulo lwamandla: iintlobo ezimbini ezibalulekileyo ze-analog chip

Iimveliso zekhonkco leSignali, ezibandakanya ubukhulu becala i-amplifiers kunye nabaguquli bedatha, bajongana neemfuno zentsebenziswano yolwazi.Kwinkqubo edibeneyo ye-digital-to-analog, inkqubo epheleleyo yokucwangcisa umqondiso ihamba ngolu hlobo lulandelayo.

IiSensors: Iimpawu zomzimba ezikrwada ezivela kwihlabathi langaphandle, ngokwesiqhelo isandi, imifanekiso, ubushushu, ukufuma, uxinzelelo, njl. yangoku.

I-Amplifaya kunye nezihluzi: Iimpawu ze-analog zicutshungulwa ziiyunithi zokulungiswa komqondiso ezibandakanya i-amplifiers kunye nezihluzi.I-amplifier isebenzela ukukhulisa iimpawu ezincinci, ezibuthathaka ze-analog ukuziqhelanisa noluhlu olupheleleyo lwegalelo le-ADC;icebo lokucoca lisebenza ikakhulu kumgca-mda umqondiso ukwanelisa iimfuno ze theorem yesampulu yeNyquist.

Isiguquli sedatha: i-ADC iguqula i-voltage esetyenzisiweyo / isignali yangoku kwi-discrete yedijithali ehambelanayo, enikezelwa kwiyunithi yedijithali elandelayo ukuze iqhutywe.

Ukusetyenzwa kweDijithali: Ubuninzi bedijithali bufakwe kwidijithali yinkqubo yokucubungula idijithali (MCU, DSP, okanye FPGA), edla ngokusetyenziselwa ukuphumeza i-algorithms yokucwangcisa umqondiso wedijithali.

Isiguquli sedatha: Izixa zedijithali ezidityanisiweyo emva kokulungiswa kwenkqubo yedijithali zithunyelwa kwi-DAC, apho ziphinda ziguqulwe zibe ngumqondiso we-analog oqhubekayo.

Izihlungi: Njengoko i-DAC ye-output signal iqulethe "inyathelo" i-high-frequency components, i-reconfiguration filter isetyenziselwa ukucoca ingxolo ye-high-frequency, okubangela ukuba kulungiswe isignali yokuphuma kwe-analog.

Eyona nto ibalulekileyo kwezi yi-amplifier yokusebenza kunye ne-converter yedatha.

Ama-amplifiers asebenzayo "ziibhloko zokwakha ezisisiseko" zeesekethe ze-analog kwaye zisetyenziselwa uluhlu olubanzi lwezicelo.Ii-amplifiers ezisebenzayo zizijikelezo zokukhulisa ezongeza kwaye zidibanise imiqondiso ye-analog kwaye zihlala zisetyenziselwa ukukhulisa iimpawu ezincinci, ezibuthathaka zibe zinkulu.Ngexesha elifanayo, ii-amplifiers zokusebenza zisisiseko sezixhobo ezininzi ze-analog, ezifana nabaguquleli be-digital-to-analog, abaguquleli be-current-to-voltage, izihlungi, abathelekisi, kunye nabalawuli bemigca.Kunokuthiwa ama-amplifiers asebenzayo "ziibhloko zokwakha ezisisiseko" zeesekethe ze-analog.

Abaguquli bedatha yibhulorho phakathi kwe-analog kunye neenkqubo zedijithali kwaye zibalulekile.I-analog-to-digital converter (ADC) inoxanduva lokuguqula iimpawu ze-analog kwiimpawu zedijithali kunye ne-digital-to-analog converter (DAC) inoxanduva lokuguqula iimpawu zedijithali kwiimpawu ze-analog.Ii-Sensors ziguqula amaqondo obushushu ehlabathi lokwenyani, uxinzelelo, izandi, njl.njl. zibe ziimpawu zombane, eziziimpawu ze-analog kwaye azinakubonwa kwaye ziqhutywe ziinkqubo zedijithali.Kuphela kungokuguqulwa yi-ADC apho zinokuthi zifakwe ekhompyutheni ze ziqhutywe yi-MCU.Ukongeza, izithethi, njl.njl. zidinga igalelo lesiginali ye-analog ukuze zisebenze, ngoko ke ii-DACs ziyafuneka ukuguqula ukukhutshwa kweempawu zedijithali ngenkqubo yedijithali zibe ziimpawu ze-analog.Ngoko ke, nanini na xa ukuqhutyelwa kwedijithali kubandakanyeka, i-converter yedatha kufuneka ibe khona.

Ii-Op-amps zisisiseko sezixhobo ezininzi ze-analog, umzekelo, izihluzi zenziwe nge-op-amps kunye ne-resistators.

Abaguquleli bedatha baquka abaguquli bedijithali ukuya kwi-analog (DACs) kunye nabaguquleli be-analog-to-digital (ADCs)

Ulawulo lwamandla luyimfuneko kwiisekethe zombane.Ngethuba nje inkqubo ye-elektroniki idinga unikezelo lwamandla, izixhobo zombane eziqhelekileyo ziyi-adapters zamandla, iibhetri, njl. Ngokuxhomekeke kuhlobo lwegalelo kunye nemveliso yangoku, sinokuhlela abaphathi bamandla kwiindidi ezi-4 eziphambili: AC-DC (rectifier), AC. -AC (inverter, njl.), DC-DC (chopper), kunye ne-DC-AC (inverter).

Ukutshintshela izilungisi (AC-DC) ikakhulu kunoxanduva lokuguqula amandla e-AC abe ngamandla e-DC kwaye aqhele ukufunyanwa kwiiadaptha zamandla zeelaptops.

Iziguquli ze-AC-AC (AC-AC) zinoxanduva lokuguqula i-frequency ethile yamandla e-AC ukuya kwelinye elingaguqukiyo okanye eliguquguqukayo lamandla e-AC.

Isiguquli se-DC-DC (DC-DC) siguqula amandla e-DC abe ngawamanye amandla e-DC aneempawu ezahlukeneyo zokuphindaphinda, isigaba, sangoku kunye nombane.

Ii-Inverters (DC-AC) ziguqula iziguquli eziguqula amandla e-DC kumandla e-AC, ezinye zibabiza ngokuba ngabaguquli, kwaye ngamacandelo aphambili emveliso ye-AC yokutshintsha umbane kunye nonikezelo lwamandla olungaphazamisekiyo (UPS).

Iitshiphusi zolawulo lwamandla zizijikelezo zolawulo lwamandla ezidityanisiweyo ezimisebenzi yazo ingundoqo kulawulo lwamandla ombane, ukonyuswa kwamandla ombane, ukuguquguquka okuthe rhoqo, ukuguqulwa kwe-AC-DC, njl.njl. Zahlulwe zaba ngabalawuli bamandla ombane (LDO), iitshiphusi zecharge-pump, DC. -DC converters (DC-DC), AC-DC converters (AC-DC), iitshiphusi zomqhubi we-LED, njl. Izicelo eziqhelekileyo zitshaja kunye nabaqhubi be-LED kubathengi be-electronics ezifana neefowuni eziphathwayo kunye neekhompyutha zeencwadana.Umzekelo, i-voltage elawula amandla ehlisa amandla ombane angama-220V kwaye ikhuphe i-DC ezinzileyo yombane ephantsi ukuze isetyenziswe kwiikhompyuter zamanqaku;Abaqhubi be-LED banyusa amandla angaphakathi kwiifowuni eziphathwayo ukuqhuba ukukhanya kwekhamera.
