IRFZ44N: yonke into ofuna ukuyifumana malunga nale transistor yeMOSFET

Ukusetyenziswa kunye neArduino kukho ubuninzi bezinto ze-elektroniki onokuzisebenzisa. Ezi zixhobo azikhethi kuphela iArduino, kodwa zezona ziluncedo kakhulu kwiiprojekthi zakho. Umzekelo woku Abahambisa iiMOSFET esichaze kumanqaku angaphambili. Kodwa ngeli xesha siza kukuxelela yonke into ekufuneka uyazi malunga nenye: IRFZ44N.

Ngamanye amaxesha uyakufumana usebenza neprojekthi apho kufuneka usebenze umthwalo nge-microcontroller. Ukuze kwenzeke ngeevolthi eziphethwe yi chip yangoku ye-MCU Kuyimfuneko ukusombulula iingxaki ezithile ukuze zikwazi ukusebenza kwii-MOSFET ze-transistors ezinemithamo enokuthi isuke kwi-5v iye kwi-3.3v okanye ngaphantsi.

Ewe, I-IRFZ44N yi-MOSFET transistor njengoko sele ndivakalisile. Ine-TO-220-3 yokupakisha yohlobo, nangona inokuboniswa kwezinye iifomathi, kwaye nge-pinout elula ngokulula kunye nezikhonkwane ezintathu zomnyango, idreyini, umthombo (kuloo myalelo ukusuka ekhohlo ukuya ekunene ukuba ujonga isuka ngasemva), Oko kukuthi, apho inemibhalo ebhaliweyo). Inokuveliswa ngabavelisi abohluke kakhulu, ke unokubonisana ne- Idatha yekhonkrithi.

Le MOSFET ine Uhlobo lwendlela ye-N, Njengoko igama layo libonisa. Ngaphandle koko, inezinye iinkcukacha zobugcisa ezinje:

• Umbane wokwahlulahlula umthombo: 60 V
• Ukuqhubeka kokucinezela ngamandla:50A
• IiRdsamandla: 22mOhms
• Ombane weSango-umthombo: 20 V
• Uluhlu olusebenzayo lobushushu: -55 ukuya ku-175ºC
• Ukutshatyalaliswa kwamandlauya: 131w
• Ixesha lokuwa: 13ns
• Ixesha lokusekwa: 55ns
• Ukucima ukulibaziseka: 37ns
• Ukulibaziseka kokuxhuma okuqhelekileyo: 12ns
• Price: iisenti ezimbalwa. Ungathenga Ipakethe ye-10 IRFZ44N kwiAmazon ngexabiso elingaphantsi kwe- € 3.

Umzekelo wesicelo kunye neArduino

Masibeke umzekelo wesicelo se-IRFZ44N ngeArduino kunye nezikhonkwane zayo PWM. Kwaye kukuba xa ufuna ukulawula imithwalo ngendlela eyahlukileyo yokulawula isantya seemoto, amandla okukhanyisa, njl.

Okokuqala, xa ufuna ukudibanisa okanye ukunqamla indlu kumthombo wamandla, kuhlala kunjalo Sebenzisa iswitshi yakudala okanye ukudluliswa. Kodwa loo nto ivumela ukuvula nokucima, kokubini kwimeko enye kunye nenye.

Nge-transistor inokulawulwa ngophawu lombane, njengakwidlulisi, ukwenza ulawulo luzenzekelayo, kwaye uya kuba noluhlu izibonelelo ezinje ngolawulo olwahlukileyo yomthwalo ukuze ukwazi ukukwenza nge-PWM. Endaweni yoko, ikwabandakanya ezinye iingxaki ezinje ngokubalwa kwamaza okutshintsha, ukusebenza kweevolthi, njl.

por ejemploKhawufane ucinge ukuba ufuna ukuqhuba imoto yombane eyi-12v kwisiqingatha sesantya esikaliwe. Uya kuba uyazi ukuba ngokwenza oko akunakulunga ukuthoba amandla ukuya kwi-6v ngaphandle kokungaphezulu ... kunokwenzeka ukuba baya kuhlala benganyakazi bonyusa ubushushu babo kwaye benomngcipheko wokonakalisa into leyo.

Endaweni yokuba kwenziwe ntoni nge PWM kukusebenzisa iimpembelelo ezininzi kumandla ombane ngexesha lokudibanisa nokucima (ukubetha) ukuze imoto isebenze ngendlela ofuna ngayo, njengoko sibonile kwinqaku le-PWM, kwaye sibonisa isantya esisebenzayo semoto ngaphandle kokuchaphazela i-torque okanye I-motor torque.

Ukuza kuthi ga ngoku yonke into ichanekile, kodwa ... kuya kwenzeka ntoni kwi isicelo sokukhanyisa? Ewe, ngokungafaniyo nemoto, apho kukho i-inertia, kwisibane, ukuba itshintshiwe njenge-PWM kwisantya esisezantsi, iiflickers ezicaphukisayo zenzeka esingazixabisi kwimoto. Nangona kunjalo, kwimeko ye-injini, ezinye iingxaki zoomatshini zexesha elide zingenziwa ngokuya 'jerk'.

Kwaye konke oku kunxulumene nantoni ne-IRFZ55N? Ewe, ukuba ufuna ukusebenza kakuhle nge-PWM, esi sixhobo sinokuzisombulula zonke ezi ngxaki. Ukongeza, inokulawula ukuya kuthi ga kwimisinga ye-50A, enika amandla angaqhelekanga kwiimoto ezinamandla ngakumbi. Khumbula ukuba njengoko benditshilo ngaphambili, ingxaki ngezikhonkwane ze-Arduino PWM kukuba umbane wazo awonelanga ukulawula izinto ezithile, ezinje nge-12v, 24v motor, njl.

Ngo-Arduino kunye nemoto, ngalo mzobo uqhagamshelo ulula onokuwubona, unokufumana umzekelo osebenzayo wento endikhe ndayiphawula. Ke unako ulawulo 12v motor nge-MOSFET IRFZ44N ngendlela elula.

Ukuze uqonde ngcono ukusebenza kwe-IRFZ44N transistor yoluhlobo lwesicelo, ukubek'esweni kuya kusetyenziswa apho uya kuba nakho ukufaka amaxabiso aqondwayo kwi-0 y 255 ukubanakho ukumodareyitha iimoto kunye nokujonga iziphumo.

Ngokuphathelele sketch khowudi yeArduino IDE, inokuba lula

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!");
  }
