Voltage Divider: Nhungamiro kune Voltage Regulation muElectroniki Circuits

Iyo voltage divider formula chishandiso chinogoneka uye chiri nyore kushandisa chinokutendera kuti uverenge inobuda voltage kubva kune voltage divider circuit, chinhu chakajairika mumagetsi regulation system. Kunyangwe iwe uri kugadzira maseketi akareruka kana kushanda neakawanda akaomarara masisitimu emagetsi, iyi fomula chinhu chakakosha mumidziyo yako yemagetsi.

Verenga kuti uongorore kuti voltage divider formula chii, mashandiro ayo, uye kuti inoshanda sei kune akasiyana masisitimu edunhu. Iwe unozodzidzawo mashandisiro eformula iyi kunyatsoona chikamu chemagetsi ekuisa anodiwa mumaseketi ako.

Chii chinonzi Voltage Divider?

A voltage divider idunhu rekutanga rakagadzirirwa kuderedza voltage. Iyo inogovera iyo yekupinda voltage mukati mechikamu chedunhu, kazhinji resistors, nenzira inodzorwa. Muenzaniso wakatwasanuka wevoltage divider unosanganisira maviri anopikisa akabatana munhevedzano, uko magetsi ekuisa anoiswa paairi maviri, uye magetsi anobuda anotorwa kubva panosangana pakati pavo.

Iyi dhizaini dhizaini inowanzo shandiswa kugadzira chaiyo voltage mazinga kubva kune imwechete voltage sosi uku uchivimbisa inogara iripo kuburikidza nechikamu chimwe nechimwe munhevedzano wedunhu.

Iyo Voltage Divider Formula uye Mashandisirwo Ayo

Iyo voltage divider formula inoshandiswa kuverengera yakabuda voltage inoguma nekuisa voltage yekupinza pamaviri akateedzana-akabatana resistors. Iyi fomula yakavakirwa muOhm's Law (V = IR), iyo inotaura kuti ikozvino kuburikidza nevanopikisa yakafanana nekuti vanogovana nzira imwe chete iripo.

Kuti uverenge kudonha kwevoltage pane yechipiri resistor, unogona kushandisa inotevera formula:

$V_{out} = V_{in} \nguva \frac{R2}{R1 + R2}$

​

Where:

• waini: Iyo yekupinza voltage inoshandiswa kune yakatevedzana resistors.
• R1 uye R2: Kupokana kweaviri anopikisa.
• Mhere: The goho voltage kuyerwa mhiri R2.

Iyi fomula inogona zvakare kuwedzerwa kune maseketi ane anopfuura maviri resistors munhevedzano. Nekushandisa iyo voltage divider formula kakawanda kune yega yega resistor, unogona kuona kudonha kwevoltage pane chimwe nechimwe chikamu.

Zvinoenderana neOhm's Mutemo, iyo yakakwirira kupikisa, iyo yakakura kudonha kwevolti pairi. Sezvineiwo, maresitorendi ane yakaderera kupikisa kukosha anozove nemadonhwe madiki emagetsi.

Kuti ushandise fomura yekuparadzanisa magetsi zvinobudirira, isa V yako mukati uye resistor values ​​mu calculator kana circuit simulation tool. Voltage inobuda ichaverengerwa otomatiki uye icharatidzwa mu volts.

Kupinda muVoltage Divider Rule

Iyo voltage divider mutemo musimboti wakakosha mukuwongorora wedunhu unoraira kuti magetsi ekupinza anogovaniswa sei zvakaenzanirana pane zvakatevedzana-zvakabatana zvikamu. Mutemo uyu unonyanya kukosha mumaseketi eDC, uko hukama pakati pemagetsi, ikozvino, uye kuramba kunotevera Mutemo waOhm nenzira yakatwasuka. Zvinoenderana neiyo voltage divider mutemo, kudonha kwevoltage pane imwe neimwe resistor munhevedzano wedunhu yakanangana nekupokana kwayo kunoenderana nekupokana kwese kwedunhu.

Mumaseketi eAC, kushandiswa kweiyo voltage divider mutemo kunowedzera kuoma nekuda kwekuvapo kwezvinhu zvinogadziriswa, senge capacitors uye inductors. Izvi zvikamu zvinounza impedance, inova frequency-inotsamira uye ine zvese kupikisa (chaiyo chikamu) uye reactance (yekufungidzira chikamu). Iyo impedance ye capacitors uye inductors inosiyana nekuwanda kweiyo AC chiratidzo, zvichikonzera shanduko yechikamu pakati pevolti uye yazvino. Naizvozvo, kana uchiongorora maseketi e AC, mutemo wevoltage divider unofanirwa kuverengera aya ekuchinja kwechikamu uye frequency-inotsamira maitiro eiyo impedance, zvichiita kuti kuverengera kwevoltage kudonha kuwedzere kuoma.

Iyo Voltage Ladder

Voltage ladder idunhu rine maresitorendi akati wandei akabatana munhevedzano, ine voltage inoiswa pane network yese. Mudunhu rakadaro, kudonha kwemagetsi pane imwe neimwe resistor inotarwa nekukosha kwayo kunoenderana nekupokana kwese kwemanera. Iyo yazvino inoramba yakafanana mudunhu rese, asi kudonha kwevoltage kunowedzera paunenge uchidzika pasi nemanera.

Kuti uverenge vhoriyamu pane chero nzvimbo mumanera, iwe unokamura iyo yakazara voltage nekupikiswa kwese uye kuwedzera nekupokana kwechikamu chekufarira.

Input Voltage uye Voltage Drop

Kudonha kwevoltage kuyambuka resistor mune voltage divider circuit inosarudza zvese zvinobuda voltage uye kupatsanurwa kwevoltage mudunhu rese. Mune yakapfava maviri-resistor voltage divider, iyo yekuisa voltage inoiswa mukati mekutevedzana kusanganiswa kweanopikisa, uye inobuda voltage inotorwa kubva kune yechipiri resistor.

Nekushandisa Kirchhoff's Voltage Law uye Ohm's Mutemo, unogona kuona kudonha kwevoltage pane yega yega resistor mudunhu, zvinoenderana neiri kuyerera nepakati pavo uye yakazara magetsi ekupa.

Kushanda Kushanda kweVoltage Dividers

Voltage dividers inoshandiswa mumhando dzakasiyana dzekushandisa, kusanganisira:

• Potentiometers: Potentiometer i resistor inochinjika inoshanda semugovanisi wemagetsi anogadziriswa. Inobvumira kudzora kwakanyatsojeka pamusoro pemazinga emagetsi, anoshandiswa zvakanyanya mumidziyo yakaita sekutonga vhoriyamu uye maseketi ekugadzirisa.

• Kuyera Voltage Yakakwira: Kuyera voltage yakakwira zvakananga kunogona kuva nengozi uye kukuvadza michina. Chinoparadzanisa voltage chinogona kuderedza voltage yakakwira kusvika padanho rakachengeteka rekuyera nekudonhedza voltage panzvimbo yakachengeteka.

• Kuziva Kuramba Kusingazivikanwe: Kana uine simba remagetsi uye resistor inozivikanwa, unogona kuona simba risingazivikanwe nekugadzira circuit yakapfava yekuparadzanisa magetsi. Yera simba remagetsi pa resistor inozivikanwa, uye shandisa fomura yekuparadzanisa magetsi kuti uverenge simba risingazivikanwe.

Zvakanakira uye Zvakaipa zveVoltage Dividers

Voltage dividers inobatsira, asi ine zvimwe zvinogumira:

• Kunzwa Kwekupisa: Kuramba kwezvinhu zvakawanda kunosiyana zvichienderana nekupisa. Kunyange zvazvo izvi zvichigona kuoma kuyera voltage, kushandisa resistors dzakagadzirwa nezvinhu zvakafanana mu voltage divider kunogona kubatsira kuderedza izvi sezvo resistors dzese dzichichinja resistance zvakafanana nekupisa.

• Kurasikirwa Nesimba: Mukushandiswa kwesimba guru, zvinodzivirira muvoltage divider zvinobvisa simba sekupisa, izvo zvinogona kukonzera kusashanda zvakanaka uye matambudziko ekupisa.

Pasinei nezvipingamupinyi izvi, magetsi anopatsanura anoramba ari mhinduro inoshanda yekugadzira akawanda voltage mazinga kubva kune imwechete sosi mumaseketi akasiyana siyana.

mhedziso

Kunzwisisa mashandiro anoita mavolti dividers uye mashandisiro eiyo voltage divider formula kwakakosha kune chero munhu ane chekuita nemagetsi. Kunyangwe iwe uri kushanda pamaseketi akareruka kana akaomesesa masisitimu, iyo misimboti yevoltage division inokubatsira iwe kubata nekudzora mazinga evoltage zvinobudirira.

Nekugona iyi yakakosha pfungwa, unogona kugadzira mamwe maseketi anoshanda, kugadzirisa matambudziko zvakanyanya, uye kuwana mhedzisiro iri nani mumapurojekiti ako emagetsi.
