How kuti VLF nemaoko avo kubva chinyorwa zvinhu?

Munyaya ino uchadzidza sei kugadzira CFP nemaoko avo kubva chinyorwa zvinhu. Uye zvinodiwa achapiwa chete kune zvivako chinogona kutevedzera kunyange mutsva redhiyo mudzidzi uyo chete vakadzidza kuverenga magetsi schematics. Asi zvinhu zvokutanga pakutanga. Nokuti kutanga zvinokosha kuziva kuti pane mhando ina mano; muna sepombi, transistors, Integrated matunhu, uyewo hwakakanyiwa, izvo ingasanganisira marudzi vanoverengeka masero. Somuenzaniso, imwe preamplifier inogona kuvakwa pamwe transistors uye kugumisa - mwenje.

How kusarudza zano?

Zvinofanira kusarudza chii iwe kutarisira kubva mudziyo uye chero munda vari kurishandisa. On ichi zvinoenderana kuti Ulf zano mhando ichashandiswa. Asi chero zvakadaro, Chokwadi, kusarudza hwemazuva maatomu akafanana nechimwe - ndiro inonyatsobudirira zvichachipedza. Cherechedza kuti rambi zvemichina ane hombe drawback - hombe simba rive. Hongu uye utsvake transformers achava zvakaoma. Uye kana pasina ndiri mwenje, ipapo kukundikana rimwe, unorasikirwa nesimba rako. Kuti mwenje Ulf nemaoko iri nyore, asi magadzirirwo kwaanoda yainetsa.

Transistor magadzirirwo tarisa zvakawanda anokwezva, asi ivo vane guru kuvamirira. With pachena kunzwisisa redunhu iwe kuwana simba shoma chaizvo. Kunenge kuti unogona kuwana guru redunhu puranga, iro okunze vanosarudzirwa pedyo nepedyo, uye simba dzose mano - hapana anopfuura 10 watts or. Naizvozvo, zvazvinosarira imwe pfungwa yechitatu - kushandiswa machipisi. Simple, yakavimbika, hunogara (pasi kwomuzvarirwo kushandiswa).

pcb

Kuti kugadzwa zvinobvira mune nzvimbo diki, saka iwe zvingava zvakakwana kuti chimedu foil zvinhu 30x30 mm. Asi zvinogona kushandiswa inonzi hove - pcb yakabvooka nokuda vanomhanyisa okunze uye makwapa akasvibirika duku simbi vakavakomberedza. Izvi zvichava chinetso. Kubereka nyore VLF nemaoko avo - zvinoita kwemaminitsi.

Kana chete foil pcb, uchava kugura grooves pairi. Vachavesa chiduku revatungamiriri anoverengeka mhangura yakagadzirwa. Uye achava kugadzwa zvose pezvokuvamba gudzazwi. Ona kuti simba nerubatsiro anogona kuitwa sezvo chakaparadzana huru chikamu CFP, uye pamwe naye.

Power gudzazwi

Kazhinji, mudzimba amps ndiro simba ari 9-18 volts zvakakwana. Ava mureza tsika voltage transformers anogona kuwanikwa anenge kwose kwose. Pomugove Dunhu iri mureza - transformer, mana diodes uye capacitor vanenge 100 microfarads nokuda kuroora kuparadza rakatumbuka chezvinonhuwira romugove voltage.

Asi zvizhinji kunoenderana worudzii VLF zano richashandiswa munyaya kugadzirwa yenyu. Kana uchironga kuunganidza Ulf yakaderera-simba, ipapo unofanira kutarisa datasheet chip fari, yauri kuenda kushandisa. Bhadharai ngwariro chaiyo mutsetse iyo yakanatsa romugove voltage siyana. Kana bvumidzwa donhwe kusvika 5, zvinokwanisika kushandisa chero foni iri mundiro.

How akakokera gudzazwi

Ulf pamusoro machipisi zvinoda okuwedzera kutonhora. Dzimwe nguva kunyange yakaderera simba magadzirirwo emit yakawanda kupisa. Somugumisiro, vaifanira kushandisa aruminiyamu radiators kuti nyatsoshanda kutonhora.

Kana ukavaka VLF simba namaoko ako, unofanira kufungisisa pamusoro kutonhora nyaya. Zvinogoneka kuti chimwezve vanofanira kuisa kutonhora.

Kazhinji, paungano Ulf nemaoko enyu hakufaniri kuoma. zvinhu zvose zvine chokuita maererano zano. Uye shure kuzvidzora uye akaramba Check ndiko kwakapa uye rinobatanidza mazano chiratidzo kunobva. Hatigoni kutaura kuti goho mutoro kunodiwa - mu mutauri. At basa Chip gudzazwi anotanga kushanda pasina configuration. Zvinofanira kucherechedzwa kuti gudzazwi redunhu zvakanakisisa kushandisa chete uya anopiwa datasheet pamusoro chip. In izvi muenzaniso purogiramu vari kufungwa zvinhu zvose, kunyange zviduku nuances imwe chip. Uye kushanda zvakanaka chete pachishandiswa nuances izvi. Kushandisa zano kubva untrusted manyuko, munosangana nedambudziko kunokuvadza ari chip. Uye dzimwe nguva mutengo waro nani kumusoro.
