IRFZ44N: duk abin da kuke buƙatar sani game da wannan transistor na MOSFET

Don amfani tare da Arduino akwai yawancin kayan haɗin lantarki zaka iya amfani dasu. Waɗannan na'urorin ba kawai keɓaɓɓu ne ga Arduino kawai ba, amma sune mafi amfani ga ayyukanku. Misalin wannan sune transistors MOSFETs cewa mun bayyana a cikin abubuwan da suka gabata. Amma wannan lokacin za mu gaya muku duk abin da kuke buƙatar sani game da takamaiman ɗaya: IRFZ44N.

Wani lokaci zaka sami kanka aiki tare da aikin da kake buƙatar kunna kaya tare da microcontroller. Don hakan ya zama mai yuwuwa tare da abubuwan sarrafawar da yanzu MCU guntu Wajibi ne don warware wasu matsaloli don iya yin aiki akan transistors MOSFETs tare da ƙananan wuta wanda zai iya zuwa daga 5v zuwa 3.3v ko lessasa.

To, IRFZ44N sigar transistor ne na MOSFET kamar yadda na riga nayi tsokaci. Yana da nau'ikan marufi na TO-220-3, kodayake ana iya gabatar da shi a cikin wasu sifofi, kuma tare da sassauƙa mai sauƙi tare da misalai guda uku na ƙofar, magudana, tushe (a cikin wannan umarnin daga hagu zuwa dama idan kun kalle shi daga baya), ma'ana, inda take da rubutun). Ana iya ƙera shi ta masana'antun daban, don haka zaka iya tuntuɓar takaddun bayanan kankare.

Wannan MOSFET yana da N-type tashar, Kamar yadda sunan ta ya nuna. Bayan wannan, yana da wasu cikakkun bayanai na fasaha kamar:

Misalin aikace-aikace tare da Arduino

Bari mu sa misalin aikace-aikace na IRFZ44N tare da Arduino da fil PWM. Kuma shine lokacin da kake buƙatar sarrafa kaya ta hanya mai canzawa don daidaita saurin Motors, ƙarfin hasken wuta, da sauransu, zaka iya zuwa waɗannan PWM fil da transistors kamar wanda muke da shi yau.

Da farko dai, lokacin da kake son haɗawa ko cire haɗin gida daga tushen wuta, yawanci galibi ne yi amfani da sauyawa na gargajiya ko gudun ba da sanda. Amma wannan kawai yana ba da damar kunnawa da kashewa, duka a cikin wani yanayi da ɗayan.

Tare da transistor ana iya sarrafa shi tare da siginar lantarki, kamar yadda yake tare da relay, don sarrafa kansa sarrafawa, kuma kuna da jerin fa'idodi irin su iko mai canzawa na kaya don iya aiwatar dashi ta hanyar PWM. Madadin haka, hakanan ya haɗa da wasu rikitarwa kamar ƙididdigar hanyoyin ruwa da za a sauya, ƙarancin aiki, da dai sauransu.

de amfaniKa yi tunanin cewa kana buƙatar tafiyar da wutar lantarki mai karfin 12v a rabin saurinta. Za ku riga kun san cewa a aikace ba zai dace da rage ƙarfi zuwa 6v ba tare da ƙarin ba ... mai yiwuwa ne su ci gaba da kasancewa marasa motsi suna ƙaruwa da zafin jikinsu kuma tare da haɗarin lalata abun.

Madadin haka, me aka yi da PWM shine ayi amfani da abubuwa da yawa zuwa ga wutar lantarki mara suna a cikin wani lokaci na haɗawa da cire haɗin (bugun jini) don motar ta yi aiki yadda kake so, kamar yadda muka gani a cikin labarin PWM, da kuma samfurin saurin aiki na motar ba tare da ya shafi tasirin ko injin karfin juyi

Ya zuwa yanzu komai daidai ne, amma ... menene zai faru a cikin aikace-aikacen hasken wuta? Da kyau, ba kamar motar ba, inda akwai rashin ƙarfi, a cikin hasken wuta, idan aka canza kamar yadda yake tare da PWM a ƙananan mitoci, masu ɓoyi masu ban tsoro suna faruwa wanda da wuya mu yaba a cikin motar. Koyaya, koda a yanayin injin ne, ana iya ƙirƙirar wasu matsalolin inji na dogon lokaci ta hanyar zuwa 'jerk'.

Kuma menene duk wannan ya shafi IRFZ55N? Da kyau, idan kuna son aiki mai sauƙi tare da PWM, wannan na'urar zata iya magance waɗannan matsalolin. Bugu da kari, zai iya sarrafawa har zuwa igiyar ruwa ta 50A, wanda ke bayar da dama ta ban mamaki ga wasu karin injina masu karfi. Ka tuna cewa kamar yadda na fada a baya, matsalar da ke tattare da fil din Arduino PWM shine cewa karfin su bai isa ya sarrafa wasu abubuwa ba, kamar su 12v, 24v motor, da dai sauransu, saboda haka transistor da kuma wata hanyar waje zasu iya taimaka maka.

Tare da Arduino da mota, tare da wannan zane mai sauƙi wanda zaku iya gani, zaku iya samun misali mai amfani akan abin da nayi tsokaci. Don haka zaka iya sarrafa motar 12v tare da IRFZ44N MOSFET ta hanya mai sauƙi.

Don ku kara fahimtar aikin transistor na IRFZ44N don wannan nau'in aikace-aikacen, za a yi amfani da allon saka idanu daga inda za ku sami damar shigar da ƙimar da aka fahimta shigar da 0 y 255 don iya daidaita motar kuma kiyaye sakamakon.
