IRFZ44N: zvese zvaunoda kuti uzive nezve ino MOSFET transistor

Kuti ushandise naArduino pane kuwanda kwezvinhu zvemagetsi zvaunogona kushandisa. Aya madhivha haangori chete kune Arduino, asi ndiwo anonyanya kushanda kune ako mapurojekiti. Muenzaniso weizvi ndewe transistors MOSFETs izvo zvatakatsanangura muzvinyorwa zvakapfuura. Asi ino nguva isu tichakuudza zvese zvaunoda kuti uzive nezve yakatarwa imwe: IRFZ44N.

Dzimwe nguva iwe unozviwana uchinge uchishanda neprojekiti mauri yaunoda kumisikidza mutoro ne microcontroller. Kuti izvo zviitike nemitero inobatwa ne yazvino MCU chip Izvo zvinodikanwa kugadzirisa mamwe matambudziko kuti ugone kuita pane transistors MOSFETs ane voltages ayo anogona kubva kubva pa5v kusvika ku3.3v kana zvishoma.

Zvakanaka, iyo IRFZ44N ndeye MOSFET transistor sekutaura kwandamboita. Iyo ine TO-220-3 mhando yekupakata, kunyangwe ichigona kuiswa mune mamwe mafomati, uye neine nyore nyore pinout nematatu chaiwo mapini emusuwo, dhureni, sosi (mune iwo marongero kubva kuruboshwe kurudyi kana iwe ukatarisa iyo kubva kumashure), ndiko kuti, iko kune zvakanyorwa). Inogona kugadzirwa nevagadziri vakasiyana kwazvo, kuti ugone kubvunza iyo kongiri datasheet.

MOSFET iyi ine N-mhando chiteshi, Seizvo zita rayo rinoratidza. Kunze kweizvozvo, ine zvimwe zvehunyanzvi ruzivo se:

• Drain-sosi yekuparadzanisa voltage: 60 V
• Kuenderera mberi kwekudonha kusimba:50A
• rds: 22mOhms
• Gedhi-sosi voltage: 20 V
• Inoshanda tembiricha renji: -55 kusvika 175ºC
• Kuparara kwesimba:131w
• Nguva yekudonha:13ns
• Nguva yekugadzwa:55ns
• Kudzima kunonoka:37ns
• Chaizvoizvo kubatana kunonoka: 12ns
• Mutengo: masendi mashoma. Unogona kutenga 10 kurongedza IRFZ44N paAmazon isingasviki € 3.

Muenzaniso wekushandisa naArduino

Ngatiisei muenzaniso wekushandisa we IRFZ44N neArduino nemapini ayo PWM. Uye ndezvekuti kana iwe uchida kudzora mitoro munzira inoshanduka yekumhanyisa kumhanya kwemota, kusimba kwemwenje, nezvimwewo, unogona kuenda kune idzi PWM pini uye ma transistor senge iyo yatinofanira kuongorora nhasi.

Chekutanga pane zvese, kana iwe uchida kubatanidza kana kudzimura imba kubva kunesimba sosi, zvinowanzoitika shandisa yechinyakare switch kana relay. Asi izvo zvinongobvumidza kutendeuka uye kudzima, zvese mune imwe kesi uye mune imwe yacho.

Iine transistor iyo inogona kudzorwa neine magetsi chiratidzo, sekunge neiyo relay, kuti iite otomatiki kutonga, uye iwe zvakare uchave uine akateedzana e zvakanakira sekushanduka kwekudzora yemutoro yekugona kuzviita kuburikidza nePWM. Panzvimbo iyoyo, zvakare inosanganisira zvimwe zvinetswa senge kuverenga kwezvinoitika kuti zvichinjwe, kushanda voltages, nezvimwe.

kubudikidza ejemploFungidzira kuti iwe unoda kumhanyisa 12v yemagetsi mota pahafu yayo yakatarwa kumhanya. Iwe uchatoziva kuti mukuita hazvizove zvakakosha kudzikisa simba kune 6v pasina zvimwe ... zvingangoita kuti vangaramba vasina kufamba vachiwedzera tembiricha yavo uye nenjodzi yekukuvadza chinhu.

Pane kudaro, chii chinoitwa ne PWM ndeyekuisa zvishuwo zvakati kuti kumazita emagetsi mune imwe nguva yekubatanidza uye kudimbura (pulses) kuitira kuti mota ishande sezvaunoda, sezvatakaona muchinyorwa chePWM, uye modhiza kumhanya kwekutyaira kwemota pasina kukanganisa torque kana mota torque.

Parizvino zvese ndezvechokwadi, asi ... chii chingaitika mu magetsi ekushandisa? Eya, zvakasiyana nemota, iko kune inertia, mumwenje, kana ikashandurwa sePWM pane yakaderera frequency, zvinotsamwisa zvinoitika zvatisingatombo kukoshesa mumota. Nekudaro, kunyangwe mune kesi yeinjini, mamwe marefu-marefu matambudziko emagetsi anogona kugadzirwa nekuenda 'jerk'.

Uye izvi zvese zvinei nechekuita ne IRFZ55N? Zvakanaka, kana iwe uchida kushanda mushe nePWM, chishandiso ichi chinogona kugadzirisa ese iwo matambudziko. Uye zvakare, inogona kudzora kusvika parwizi rwe50A, iyo inopa chinoshamisa chinzvimbo kune mamwe emagetsi ane simba. Rangarira kuti sezvandakambotaura, dambudziko neArduino PWM pini ndeyekuti iwo magetsi haana kukwana kudzora zvimwe zvinhu, zvakaita se12v, 24v mota, nezvimwe, saka mutapuri uye chekunze chinogona kukubatsira.

NaArduino uye mota, ine iri nyore dhizaini dhizaini iwe yaunogona kuona, iwe unogona kuwana muenzaniso unoshanda weizvo zvandataura. Saka unogona kudzora 12v mota neiyo IRFZ44N MOSFET nenzira yakapusa.

Kuti iwe unzwisise zvirinani mashandiro eIRFZ44N transistor yerudzi urwu rwekushandisa, iyo serial monitor ichashandiswa kubva kwauchazokwanisa kuisa zvinonzwisiswa tsika. pakati pe0 kusvika zviuru gumi kukwanisa kuenzanisa mota nekucherechedza zvabuda.

Kana ari sketch kodhi yeArduino IDE, zvingave zvakareruka

int PWM_PIN = 6;
int pwmval = 0;

void setup() {
  Serial.begin(9600);
  pinMode(PWM_PIN,OUTPUT);
  Serial.println("Introduce un valor entre 0 y 255:");
}

void loop() {
  if (Serial.available() > 1) {
      pwmval =  Serial.parseInt();
      Serial.print("Envío de velocidad a: ");
      Serial.println(pwmval);
      analogWrite(PWM_PIN, pwmval);
      Serial.println("¡Hecho!");
  }
