Ho switjha phepelo matla ka matsoho a bona: lintlha tsa phutheho le phetoho

The bongata a maqheka elektroniki hloka ka phepelo matla ho DC gagamalo tsa volts 12. Ho switjha Power Supplies ka matsoho a hao a tla ka ladica i le entsprechen hlokahalang. Selection ha e tsoela pele litafole seea-le-boenjiniere. Matsoelintsoeke fatše transformer hlahiswa ka e ferrite lesale tse bonahalang sehlopheng - M200MN.

E le input bipetsa ka tsela e atlehileng sebelisa inductors le teng, beha hangata ka phepelo ea joalo matla kapa lipontšo tsa botho k'homphieutha. capacitor e balwa tswa capacitance le matla karo-karolelano ea mong ho e mong. rectifier e entsoe ka lebaka la ho diode borokho ka tlaase maqhubu a ho sebelisa mehaho. Joalo sesebediswa e ka fana ka matla hona joale ea ho fihlela ho 3 amperes ho khumo ea.

Sebelisoa ka seea-le-ho switjha matla phepelo oa potoloho eo e telele ba ile ba sebetsa le hlahloba, ke transistor fapoha. Selection transistors o etsoa ka entsprechen e behiloeng, letoto hantle-proven IRF tse 840, kapa VT 1 le VT3. Transistors ho fana ka mocheso hlokahala lokela ho ba le sa teba mocheso ho tlosa mocheso keketso.

Ho switjha phepelo matla ka matsoho a bona ho ea khumo karolo e itseng ea oa potoloho e fanoeng ke throttles e thehiloeng ferrite silindara ka bang 40 limilimithara ka bolelele le bophara ba limilimithara 3. Thata matsoelintsoeke e entsoe ka terata e tšoanang e le ea bobeli matsoelintsoeke ea transformer le. The tshebediso ya le mekhoa e meng bakeng sa e tiileng sehlopha khumo, empa ho tšepahala proven lipotoloho. Search ka liqeto tse ling tabeng ena e ne e tla ke tšenyo ea nako.

Boleng matla phepelo ka matsoho a bona soldered ka boto lokisitseng. Ha ho hlongoa ke ho hlokahala hore ho fana ka tsela e tloaelehileng mabone tsa mosebetsing le ventilation. Mora kulo e kgothaletswa ho hlahloba ho tšepahala ha ho hlongoa dikarolo tsa elektronike le ho ikopanya le pakeng tsa bona le litsela tsa conductive. Holim'a ka hare tsa hloekisa litlhaka kahare solder ts'ebetsong a ka lebisang oa potoloho ena.

Ho switjha Power Supplies, bokella matsoho a hae 'me a lokisetsa ho qala, e kgothaletswa ho laela resistor jwale fokotsa nakong liteko. Sena se ka ho sebelisoa e le litleloubu lebone matla a 60 W, switjha lona a motsotsoana bude e pontshi phutheho e loketseng.
