Kungenzeka ukuba kwiiprojekthi zakho Kufuneka uqwalasele umbane okanye umbane wesekethe. Umzekelo, ukuba unemveliso eyi-12v kwaye kufuneka unike amandla isekethe ye-6v, uya kufuna into enokubatshintsha. Into leyo yi isahluli sevolthi. Isekethe elula esebenza ngokufana nendlela isiguquli esinokwenza ngayo, nangona ixhomekeke kwimigaqo eyahlukileyo yokusebenza kwayo.

Ngoko ke, akufuneki udideke phakathi kwesiguquli kunye nokwahlula amandla ombaneKuba enye isebenzisa i-windings kunye ne-induction yokuguqula i-voltage enye iye kwenye, kwaye enye iyisekethe elula eyenziwe ngee-resistors ezikwaziyo ukwahlula i-voltage kwii-voltages ezimbini ezincinci. Umzekelo, isiguquli sinokuguqula i-12v kwigalelo laso libe yi-6v kwimveliso yalo, kodwa into eya kwenziwa ngumhluli kukuguqula ezo-12v zisuke kwigalelo lazo zibe zii-voltages ezimbini ze-6v kwimveliso yazo. Uyawubona umahluko?

## Yintoni isahluli sevolthi?

Un ombane okanye isahluli sevolthi Yisekethe leyo, njengoko igama layo libonisa, yahlula i-voltage ekhoyo kwigalelo layo kwezinye iivolthi ezincinci kwimveliso yayo. Ke ngoko, sisiqwenga esiphambili kwiisekethi zamandla ezifuna iivolthi ezisezantsi kunalezo zibonelelwa ngumbane, iibhetri, okanye isokethi onayo.

Ngaphambi kokuba ndinike umzekelo we-12v endihlule zibe zii-voltages ezimbini ze-6v, kodwa abahluli bevolthi abahlali beqala ngqo isiqingatha ombane igalelo. Umzekelo, kunokuba kunjalo ukuba unebhetri ye-9v kwaye kufuneka uwahlule loo ombane abeyi-6 kunye ne-3v, leyo inokwenzeka kwakhonaOko kukuthi, akufuneki zifane ...

### Imigaqo esekwe kuyo

Njengoko kunokubonwa kumfanekiso, isekethe esisiseko ilula kakhulu. Ufuna kuphela ibhetri okanye umthombo oza kuthi uqhagamshelwe emhlabeni kunye neVin emfanekisweni ukunika amandla isahlulelo. Ukwahlulahlula amandla ombane ngokwawo kuya kwenziwa kuphela ngamachiza amabini adityaniswe kuthotho. Ke, ukusebenzisa ifomula oyibonayo emfanekisweni, amandla ombane aya kubakho phakathi komhlaba kunye neVout iya kuba sisiphumo sokwahlula ixabiso lokumelana no-2 phakathi kwesixa se-R1 kunye ne-R2, kunye nokuphindaphinda iziphumo ngombane yokungena.

Kukho ukwahlulahlula amandla okuhamba kwamandla ombane, nangona kungathandwa kangako kunoko kuchasayo ...

por ejemploKhawufane ucinge ukuba unegalelo lombane we-20v, nge-R1 = 1k kunye ne-R2 = 2k. Oko kungakhokelela kwisiphumo sokwahlulahlula amandla ombane sibe yi-13v. Ewe ungadlala ngamaxabiso ezinto ezichasayo ukwenza isahlulelo sevolthi oyifunayo. Omnye umzekelo, ukuba uhluka kuphela kwi-R2 ukuze ibe yi-0,5k kuphela iya kuba sisiphumo esingu-6,6v. Kulula ngokuchanekileyo?

## Ngaba kukho ukuphindaphinda kwamandla ombane?

Ewe kukho ukuphindaphinda kwamandla ombane. Kule meko ikwayisekethe elula edibanisa ii-diode ngokudibeneyo. Oko kunika umphumo ochaseneyo, ukuphindaphinda umbane wokufakelwa ngamanqaku ahlukeneyo ukufumana iivolthi eziphezulu. Ngapha koko, ngumgaqo osetyenzisiweyo kwii-inverters ezidumileyo zeelaptops, ezishushu kakhulu, zishiya indawo eshushu ngasemva kwescreen ...

Abo ii-inverters aziyonto eyodlula isekethe eneedayidi ngokuhambelana ukuphinda-phinda amandla abonelelwa yibhetri yelaptop ukunika amandla iintlobo ezithile zeepaneli zokubonisa. Kwinqanaba ngalinye, lifumana amandla ombane de lifike kumanqwanqwa aphezulu afunwayo, ungenza nokuba ibhetri yee-volts ezimbalwa ifumane amakhulu okanye amawaka e-volts.

### Abanye ukwahlula / ukuphindaphinda

Kucacile ukuqhubela phambili ngombane kakhulu kwaye ivumela ukudibanisa olu hlobo lweesekethe kwichip enye. Ukongeza, baninzi abenzi kwimarike ezisebenzisa ezinye iintlobo zokwahlula kunye nokuphindaphinda kwisekethe enye. Abahluli kunye nokuphindaphindeka endibhekisa kubo apha ngamaxesha ewotshi. Kodwa kuya kufuneka uyazi ukuba kukwakho ukuphindaphindwa kokuqina kunye nokwahlulahlula, njl.

## Ufumana njani isahluli sevolthi

Nantsi ke iindlela ezimbini zokufumana isahlulelo sevolthi. Kwelinye icala ungazakhela isekethe esahlulayo, kuba ayifuni zinto zibizayo kwaye zitshiphu. Kodwa kwelinye icala, kukwakho nezinye izinto zombane ezibonelela ngeziphumo ezahlukeneyo zevolthi kwaye zilungele ukusetyenziswa ...

### Yenza isekethe esahlulayo

Ngumcimbi wokudlala ngokuchasene nokubala i-voltage oyifunayo kwiprojekthi yakho. Ungabona ezinye iinkcukacha kwicandelo apho kuchazwa imigaqo yeli nqaku. Ngendlela, njengombono, Ndikucebisa ukuba usebenzise i-potentiometer efana ne-R1, ke uyakuba nokuchasana okungafaniyo ukufumana iivolthi ezahlukeneyo kwimveliso ngaphandle kokutshintsha isekethe.

Ngakolunye uhlangothi, unokufumana umgca phakathi kweVout kunye nendawo yokudibanisa iVin neR1. Ke uya kuba nemilinganiselo emibini eyahlukeneyo ebesiyitshilo ekuqaleni, kunye nento enika iiterminal phakathi kwazo zombini i-resistors kunye ne-GND ...

Impazamo eqhelekileyo, xa usebenzisa imveliso eyahlulahlula amandla ombane, ukuba sele unento edityanisiweyo, iyadla kwaye inefuthe kumandla ombane. Ngesi sizathu, ukuba ubeka enye into ngokudibeneyo naleyo sele idityanisiwe, i-voltage ebonelelweyo inokuwa kwaye ayizukufana nale ububalile. Ke kuphela kukudibanisa isixhobo esinye.

### Thenga umbane

La Olula ukhetho kukuthenga ngokuthe ngqo umbane osele umiliselwe ngeziphumo ezahlukeneyo zamandla ombane, kwaye ezo zihlala zibandakanya ezinye izinto ezongeziweyo. Kukho amaxabiso aphantsi okanye eminye inemisebenzi engaphezulu ebiza kakhulu….

## Ukwahlula kunye neArduino

Ewe unakho nyusa isahluli sevolthi kwibhodi yesonka kwaye uyihlanganise neeprojekthi zakho zeArduino ngokulula. Kwaye ayisebenzi nje ukwahlula i-voltages njengoko sele sibonile, ungahlulahlula ezi zahluli ngokudibanisa ezinye izinto ezinje ngee-pushbuttons okanye iitshintshi ukuze ngombane ofanayo ukwazi ukulawula izixhobo ezininzi kwimveliso. Umzekelo, isahlulelo esilula esixhumeke ebhodini Arduino UNO Ukufunda amaxabiso kolu ngcelele

El ikhowudi yeArduino IDE Ingayinto enje:

```void setup() {
Serial.begin(9600);
}

</span>void loop() {
