Kev tsom xam ntawm cov ua rau ntawm cov hluav taws xob hluav taws xob cuam tshuam nrog chav hloov hluav taws xob
Hloov cov khoom siv hluav taws xob tuaj yeem muab faib ua ntau hom raws li lub cim hluav taws xob tseem ceeb, thiab tsis muaj suab nrov, tsis hais lub suab nrov uas yuav tsim lub sijhawm. Lawv coj sab nraud ntawm cov kab hluav taws xob hauv hom lossis hom kev sib txawv, thaum tseem rov qab mus rau qhov chaw ib puag ncig. Hloov lub zog hluav taws xob kuj tseem rhiab rau sab nraud suab nrov nkag los ntawm lub hwj huam sib tw, uas tuaj yeem kis tau rau lwm yam khoom siv hluav taws xob thiab ua rau muaj kev cuam tshuam.
Tom qab AC fais fab yog cov lus qhia rau hauv lub tshuab hloov khoom, nws hloov dua siab tshiab rau hauv lub nroog rectifiers v} v4 thiab hloov v5 ntawm qhov chaw hloov pauv siab. Lub hauv paus ntawm tus hloov pauv Transistor v5 yog nthuav dav nrog ib zaus cov zaus ntawm kaum mus rau ntau pua tus neeg yuav tsum tau txiav txim siab los ntawm cov zis tawm dc voltage vo. Cov mem tes tam sim no nthuav tawm cov raj yog txuas mus rau theem nrab Circuit Court los ntawm kev hloov pauv theem siab. Qhov sib piv ntawm cov lem nyob rau theem theem ntawm ib qho kev hloov pauv ntau zaus kuj tseem tau txiav txim siab los ntawm cov kev xav tau ntawm cov zis dC voltage vo. Lub zog ntawm mem tes tam sim no tau kho los ntawm Diode V6 thiab lim los ntawm C2 los ua DC cov zis voltage vo. Yog li ntawd, hloov lub zog fais fab yuav tsim cov suab nrov thiab hluav taws xob cuam tshuam nyob rau theem hauv qab no.
(1) Cov zaus siab hloov kho cov voj pib tam sim no ntawm thawj L1 ntawm qhov chaw siab tshaj plaws, tus raj hloov raj V5, thiab lub tshuab nqus c3 yuav tsim hluav taws xob hluav taws xob ntau. Yog tias lub capacitor filking tsis txaus, siab zaus tam sim no tseem yuav tau ua rau cov tswv yim AC fais fab mov hauv hom sib txawv.
(2) The secondary L2 of the high-frequency transformer, rectifier diode V6, and filtering capacitor C2 also form a high-frequency switch current loop that generates spatial radiation. Yog tias lub capacitor filking tsis txaus, qhov siab tshaj plaws tam sim no yuav muab xyaw ua ke nyob rau hauv daim ntawv ntawm cov hom kev sib txawv thiab kis mus sab nraud ntawm cov zis dc voltage.
(3) muaj kev faib tawm cd nruab nrab ntawm thawj thiab theem nrab ntawm cov hluav taws xob hluav taws xob zoo ib yam li cov khoom siv ntawm ob qho kev tawm ntawm ob qho kev tawm DC cov khoom siv DC ntawm cov theem nrab. Yog hais tias lub impedance ntawm ob xaim rau hauv av yog tsis sib xws, nws tseem yuav hloov mus rau ntau hom suab nrov.
(4) Cov zis Revifier Diode V6 yuav tsim kom rov qab tawm sab nraud tam sim no. Thaum ib tug diode tab tom ua nyob rau hauv kev qhia nraim rau pem hauv ntej, tus nqi tsub mus rau hauv PN hlws ris. Thaum rov qab voltage tau thov rau Diode, cov kev thim rov qab yog tsim tawm. Vim tias tus hloov pauv tam sim no yuav tsum tau kho dua los ntawm Diode, lub sijhawm rau cov diode hloov los ntawm kev txiav tawm los ntawm kev txiav tawm los ntawm kev txiav tawm luv luv. Hauv lub sijhawm luv luv ntawm lub sijhawm, kev ntxeev siab ntawm rov qab tam sim no yog tsim los ua tus nqi khaws cia ploj. Vim tias kev faib tawm, faib hluav taws xob, thiab nce qib hauv DC tso tawm kab, cov khoom ua haujlwm siab tshaj plaws yog qhov tshwm sim, uas yog hom suab nrov.
(5) Lub Load ntawm Hloov V5 yog thawj kauj L1 ntawm cov hloov pauv siab tshaj plaws, uas yog qhov thauj khoom hauv inductive. Yog li ntawd, thaum tus hloov pauv yog qhib lossis tawm, yuav muaj qhov siab tshaj voltage ntawm ob qho kawg ntawm lub transistor, thiab lub suab nrov no yuav kis tau mus rau cov tswv yim thiab cov zis tso zis.
(6) Muaj ib qho kev sib txuas ntawm lub tshuab raj hloov mus rau cov tog hluav taws xob, thiab thaum kawg mus rau hauv lub zog hluav taws xob sib txuas nrog hauv av chassis, yog li tsim dua
