Ngokwesimiso sokuklama sokusebenza kwemitha yamandla, ingahlukaniswa ngokuyisisekelo ngamamojula angu-8, imojula yamandla, imojula yokubonisa, imojula yokugcina, imojula yokusampula, imojula yokukala, imojula yokuxhumana, imojula yokulawula, imojula yokucubungula i-MUC. Imojula ngayinye yenza imisebenzi yayo ngemojula yokucubungula i-MCU yokuhlanganiswa okuhlangene nokuxhumanisa, inamathela kuyo yonke.
1. Imodyuli yamandla yemitha yamandla
Imojula yamandla yemitha yamandla iyisikhungo samandla sokusebenza okuvamile kwemitha yamandla. Umsebenzi oyinhloko wemojula yamandla ukuguqula i-voltage ephezulu ye-AC 220V ibe yi-DC low voltage power supply ye-DC12\DC5V\DC3.3V, ehlinzeka ngogesi osebenzayo we-chip kanye nedivayisi yamanye amamojula emitha yamandla. Kunezinhlobo ezintathu zamamojula wamandla asetshenziswa kakhulu: ama-transformer, i-resistance-capacitance step-down, kanye ne-switching power supplies.
Uhlobo lwe-transformer: Ukunikezwa kwamandla kwe-AC 220 kuguqulwa kube yi-AC12V nge-transformer, futhi ububanzi bamandla kagesi obudingekayo bufinyelelwa ekulungisweni, ekunciphiseni amandla kagesi kanye nokulawulwa kwamandla kagesi. Amandla aphansi, ukuzinza okuphezulu, ukuphazamiseka okulula kwamandla kagesi.
Ukunikezwa kwamandla okwehla ngokucindezelayo-ukumelana kuyisekethe esebenzisa ukusabela komthamo okukhiqizwa yi-capacitor ngaphansi kwemvamisa ethile yesiginali ye-AC ukuze kukhawulelwe umkhawulo wamanje wokusebenza ophezulu. Usayizi omncane, izindleko eziphansi, amandla amancane, ukusetshenziswa kwamandla amakhulu.
Ukunikezwa kwamandla okushintsha kwenzeka ngokusebenzisa amadivayisi okushintsha kagesi kagesi (njenge-transistors, i-MOS transistors, i-thyristors elawulwayo, njll.), ngokusebenzisa isekethe yokulawula, ukuze amadivayisi okushintsha kagesi "avuleke" futhi "acime" ngezikhathi ezithile, ukuze amadivayisi okushintsha kagesi kagesi ashaye ukuguqulwa kwe-voltage yokufaka, ukuze kufezwe ukuguqulwa kwe-voltage kanye ne-voltage yokuphuma kungalungiswa futhi umsebenzi wokulawula i-voltage othomathikhi ungalungiswa. Ukusetshenziswa kwamandla okuphansi, usayizi omncane, ububanzi be-voltage ebanzi, ukuphazamiseka kwemvamisa ephezulu, intengo ephezulu.
Ekuthuthukisweni nasekuklanyweni kwamamitha kagesi, ngokwezidingo zomsebenzi womkhiqizo, ubukhulu becala, izidingo zokulawula izindleko, izidingo zenqubomgomo kazwelonke neyesifunda ukuze kunqunywe ukuthi hlobo luni lokunikezwa kwamandla.
2. Imodyuli yokubonisa imitha yamandla
Imodyuli yokubonisa imitha yamandla isetshenziselwa kakhulu ukufunda ukusetshenziswa kwamandla, futhi kunezinhlobo eziningi zokubonisa okuhlanganisa ithubhu yedijithali, ikhawunta, okuvamileI-LCD, i-dot matrix LCD, i-touch LCD, njll. Izindlela ezimbili zokubonisa ze-digital tube kanye ne-counter zingasebenzisa ugesi wokubonisa owodwa kuphela, ngokuthuthukiswa kwegridi ehlakaniphile, kudingeka izinhlobo eziningi zamamitha kagesi ukubonisa idatha yamandla, i-digital tube kanye ne-counter azikwazi ukuhlangabezana nenqubo yamandla ahlakaniphile. I-LCD iyindlela yokubonisa ejwayelekile kumitha yamandla yamanje, ngokuya ngobunzima bokuqukethwe kokubonisa ekuthuthukisweni nasekuklanyweni kuzokhetha izinhlobo ezahlukene ze-LCD.
3. Imodyuli yokugcina imitha yamandla
Imojula yokugcina imitha yamandla isetshenziselwa ukugcina amapharamitha emitha, ugesi, kanye nedatha yomlando. Amadivayisi ememori asetshenziswa kakhulu yi-chip ye-EEP, i-ferroelectric, i-chip ye-flash, lezi zinhlobo ezintathu zama-chip ememori zinezinhlelo zokusebenza ezahlukene kumitha yamandla. I-flash iwuhlobo lwememori ye-flash egcina idatha yesikhashana, idatha yejika lomthwalo, kanye namaphakheji okuthuthukisa isofthiwe.
I-EEPROM iyimemori yokufunda kuphela ekwazi ukusulwa ephilayo evumela abasebenzisi ukuthi basule futhi bahlele kabusha ulwazi olugcinwe kuyo kungaba kudivayisi noma ngedivayisi ezinikele, okwenza i-EEPROM ibe wusizo ezimweni lapho idatha idinga ukuguqulwa futhi ibuyekezwe njalo. I-EEPROM ingagcinwa izikhathi eziyisigidi futhi isetshenziselwa ukugcina idatha yamandla njengobuningi bukagesi kumitha yamandla. Izikhathi zokugcina zingahlangabezana nezidingo zezikhathi zokugcina zemitha yamandla kuyo yonke imjikelezo yempilo, futhi intengo iphansi.
I-chip ye-Ferroelectric isebenzisa isici sezinto ze-ferroelectric ukuze ifeze ukusetshenziswa kwamandla okushesha kakhulu, okuphansi, ukugcinwa kwedatha okuthembekile okuphezulu kanye nokusebenza okunengqondo, izikhathi zokugcina eziyizigidi eziyi-1; Idatha ngeke ikhishwe ngemuva kokwehluleka kwamandla, okwenza ama-chip e-ferroelectric abe nobuningi besitoreji esiphezulu, isivinini esisheshayo, kanye nokusetshenziswa kwamandla okuphansi. Ama-chip e-Ferroelectric asetshenziswa kakhulu kumamitha wamandla ukugcina ugesi kanye neminye idatha yamandla, intengo iphakeme, futhi isetshenziswa kuphela emikhiqizweni edinga ukuba nezidingo zokugcina amagama eziphindaphindwayo.
4, imodyuli yokulinganisa imitha yamandla
Imojuli yokusampula yemitha yehora le-watt inesibopho sokuguqula isignali yamanje enkulu kanye nesignali yamandla kagesi amakhulu ibe isignali yamandla kagesi amancane kanye nesignali yamandla kagesi amancane ukuze kube lula ukutholwa kwemitha yehora le-watt. Amadivayisi okusampula amanje asetshenziswa kakhulu yilawai-shunt, i-transformer yamanje, i-Roche coil, njll., isampula ye-voltage ivame ukusebenzisa isampula ye-voltage engaphelele yokumelana nokunemba okuphezulu.
5, imodyuli yokulinganisa imitha yamandla
Umsebenzi oyinhloko wemodyuli yokulinganisa imitha ukuqedela ukutholwa kwamanje kwe-analog kanye ne-voltage, nokuguqula i-analog ibe yidijithali; Ingahlukaniswa ibe yimodyuli yokulinganisa yesigaba esisodwa kanye nemodyuli yokulinganisa yesigaba ezintathu.
6. Imodyuli yokuxhumana ngemitha yamandla
Imodyuli yokuxhumana ngemitha yamandla iyisisekelo sokudluliswa kwedatha kanye nokusebenzisana kwedatha, isisekelo sedatha yegridi ehlakaniphile, ubuhlakani, ukuphathwa okuhle kwesayensi, kanye nesisekelo sokuthuthukiswa kwe-Intanethi Yezinto ukuze kufezwe ukusebenzisana kwabantu nekhompyutha. Esikhathini esidlule, ukuntuleka kwemodi yokuxhumana ikakhulukazi yi-infrared, ukuxhumana kwe-RS485, kanye nokuthuthukiswa kobuchwepheshe bokuxhumana, ubuchwepheshe be-Intanethi Yezinto, ukukhethwa kwemodi yokuxhumana ngemitha yamandla sekubanzi, i-PLC, i-RF, i-RS485, i-LoRa, i-Zigbee, i-GPRS, i-NB-IoT, njll.
