Yuqori kuchlanishli sozlanishi DC tartibga solinadigan quvvat manbai printsipi nima
Yuqori kuchlanishli sozlanishi DC tartibga solinadigan quvvat manbai sxemasi diod, triod chegara kuchlanishi, neon lampochka, lyuminestsent chiroqning boshlang'ich kuchlanishi, kondansatkichning ish kuchlanishi, oqim va boshqalar uchun mos keladi. O'chirish 3 va 2000V oralig'ida o'rnatilishi mumkin.
Kvadrat to'lqin generatori IC2 (NE555) va uning periferik qismlaridan iborat va kvadrat to'lqin chastotasi 20 kHz. Kvadrat to'lqin signali IC2 ning ③ pinidan chiqariladi, quvvat kuchaytirgich trubkasi VT tomonidan kuchaytiriladi, impuls transformatorining T L1 birlamchi o'rashiga chiqariladi va keyin transformator tomonidan L2 ikkilamchi tomoniga ulanadi, VD2 diodi bilan rektifikatsiya qilinadi va C3 gacha zaryadlangan. C3 da doimiy kuchlanishning eng yuqori qiymati 2kV ni tashkil qiladi.
IC1a va tegishli komponentlar kuchlanish komparatorini tashkil qiladi va VD2 inverting bo'lmagan ulanish ③ pin uchun 0,7 V mos yozuvlar kuchlanishini ta'minlaydi. Taqqoslash kuchlanishi VE nuqtasidan olinadi va bo'lingan A nuqtasining kuchlanishi R1 va R2 kuchlanish bo'luvchilarining A nuqtasi orqali IC kuchlanish izdoshi orqali IC1a ning inverting terminaliga o'tkaziladi. Ish paytida, VF VaVBda pasayganda, IC2 tebranishini to'xtatadi va C3 kuchlanishi yana pasayganda, u VA ga aylanadi.
The DC output voltage is output from both ends of X1 and X2 in the circuit as the interface of the device under test. IC is LM324 and IC2 is NE555. The reverse voltage of VD1 is over 2000V and VD2 is any kind of silicon rectifier. The iron core of the pulse transformer T is made of ferrite material, and the size is E-7. When winding, first wrap L1 with 0.17mm enameled wire for 30 turns, and then wrap with 0.09mm enameled wire until L2 is full (about 1200 turns). L1 and L2 are used for winding, and polyethylene film is added between the layers. The two leads of L2 should be separated. The withstand voltage of capacitor C3 is above 2000V, and high-voltage ceramic capacitor C404M can be used. For B>100 of VT, Icm>700 mA, tanlash uchun 3DG130, 8050 va boshqalar mavjud. Nosozliklarni tuzatish vaqtida chiqish kuchlanishi faqat 40-50V bo'lsa, faqat L2 ning ikki uchini almashtiring.
