Indlela yokwenza VLF ngezandla zabo ngemathiriyeli ezindala?

Kweli nqaku uza kufunda indlela yokwenza CFP ngezandla zabo ngemathiriyeli ezindala. Kwaye kuya kunikwa kuphela ezo nezakhiwo esinokuzisebenzisa ekunabiseleni nkqu irediyo engahlawulwayo saqala nje bafunda ukufunda schematics zombane. Kodwa izinto zokuqala kuqala. Kuba isiqalo kubalulekile ukukhumbula ukuba kukho iindidi ezine zezikim: kwi kwimibhobho, transistors, iziphaluka ezihlangeneyo, kwakunye ogalelwe, leyo esenokuba iintlobo ezininzi iiseli. Ngokomzekelo, omnye preamplifier zingakhiwa kunye transistors kunye asisule - izibane.

Indlela ukukhetha le nkqubo?

Kufuneka isigqibo oko ukulindeleyo ifowuni kwaye nayiphi na inkalo uza ukuyisebenzisa. On oku kuxhomekeke hlobo ULF scheme iya kusetyenziswa ntoni. Kodwa nayiphi na imeko, Kakade ke, ukukhetha kwentsusa element mihla - yeyona isisombululo kakhulu ngempumelelo. Qaphela ukuba ubuchwepheshe isibane unalo ethile enkulu - ubonelelo zombane. Ewe kwaye ufumane ngoku abaguquli kuya kuba nzima kakhulu. Kwaye ukuba akukho isitokhwe izibane, ngoko ukusilela omnye, ulahlekelwa amandla akho. Ukuze wenze izibane ULF izandla ilula, kodwa design ujika ngumsina.

uyilo Transistor khangela nomtsalane ngakumbi, kodwa ke engxakini enkulu. Ngenxa yobunzima elikhangeleka ngayo wesekethe ufumana amandla eliphantsi kakhulu. Kusenokwenzeka ukuba ungafumana ibhodi omkhulu wesiphaluka, apho zicwangciswe izinto kufuphi enye kwenye, yaye amandla yonke yamacebo - hayi ngaphezulu kwe-10 watts. Ngoko ke, oko kuhlala sesithathu ukhetho - ukusetyenziswa neetshiphusi. Simple, oluthembekileyo, zomelele (phantsi ukusetyenziswa eziqhelekileyo).

PCB

Ukwenza ufakelo kunokwenzeka kwindawo encinane, ngoko ubuya kuba ngokwaneleyo Ngenxa yeqhekeza izinto ngefoyile ye 30x30 mm. Kodwa linokusetyenziswa-kuthiwa intlanzi - PCB kunye imigodi wayemenza izakhi kunye ezincinane etyhidiweyo elibangqongileyo. Oku kuya kuba sisisombululo ilungileyo. Ukuvelisa VLF elula ngezandla zabo - ukuba nje imizuzu.

Ukuba kukho kuphela PCB ngefoyile, kuya kufuneka ukuba ukusika vee kuyo. Baya kwenza ibhodi encinane eziliqela empumlweni yobhedu. Kubo iya kuba ufakelo zonke iziqalelo umsindo. Qaphela ukuba unikezelo amandla kungenziwa ngendlela eyahlukileyo ukusuka kwindawo engundoqo ye CFP, kunye naye.

Power sesimangalo

Njengomgaqo, amps zasekhaya Amandla okwaneleyo volts 9-18. Ezi amaxabiso esezantsi abaguquli ombane ingafumaneka phantse kuyo yonke indawo. Umphathi wesekethe supply umgangatho - sombane, ode ezine capacitor of microfarads ubuncinane 100 ukubatshabalalisa candelo nokuxuba le ombane yonikezelo.

Kodwa okuninzi kuxhomekeke kuhlobo scheme VLF ziya kusetyenziswa kuyilo yakho. Ukuba uceba ukuqokelela ULF ezisezantsi-amandla, ngoko ke kufuneka ukuba ukujonga Itheyibhile yeengcombolo ezivelileyo nj, apho uya khona wena ukuba isicelo. Nikela ingqalelo ekhethekileyo umgca apho uluhlu yonikezelo ombane elikhankanyiweyo. Ukuba ukuhla kuvunyelwe-5, kunokwenzeka ukuba ukusebenzisa nayiphi na ifowuni kwitshaja.

Indlela ukuba bahlanganise lo mshini

ULF on chips zifuna lungapholi olongezelelweyo. Maxa wambi nkqu uyilo esezantsi-amandla ayikhuphi izixa ezikhulu ubushushu. Ngenxa yoko, imfuneko yokusebenzisa radiators aluminiyam sokwehlisa kakuhle.

Ukuba kwakhiwe VLF enamandla izandla zenu, kufuneka acinge ngalo mba okupholisa. Kusenokwenzeka ukuba kukho imfuneko olongezelelweyo ukufaka ezibandayo.

Ngokubanzi, ibandla ULF ngezandla zakho akufunekanga nobucukubhede. Zonke izinto ezidibene ngokungqinelana scheme. Kwaye emva kokuba olungqinisisa aabo banelungelo kunye nokuqhubekeka na amandla kunye ifaka umthombo uphawu igalelo. Noxa kunjalo, umthwalo output iyafuneka - in isithethi. E ziyalungiswa chip msindo iqalisa ukusebenza ngaphandle uqwalaselo. Kufuneka kuqatshelwe ukuba zeesekethe wokukhulisa kungcono usebenzise kanye lowo awandibabala kwi Itheyibhile yeengcombolo ezivelileyo chip. Kule shedyuli modeli kuthathelwa ingqalelo yonke into, nkqu bokuqonda zincinane chip ethile. Ke uya kusebenza kakuhle kuphela ngokusekelwe kula bokuqonda. Ukusebenzisa inkqubo evela kwimithombo asithembekanga, uba sengozini kokonakalisa nj. Kwaye ngamanye amaxesha ixabiso layo kunokuba phezulu.
