Txhawm rau tswj hwm lub zog ntawm ntau cov khoom siv hluav taws xob, piv txwv li, cua sov, tsav tsheb, cov hluav taws xob tshwj xeeb raug siv, hu ua PWM tswj. Cov lus luv no sawv ntsug rau Pulse Dav Dav Kev Kho Mob. Yog li, lub load tsis muaj zog los ntawm kev siv hluav taws xob ncaj qha, tab sis los ntawm pulses, los ntawm kho lub luag haujlwm ntawm lub sijhawm, uas koj tuaj yeem hloov qhov tam sim no hauv Circuit Court, thiab yog li ntawd lub zog.

Cov Lus Qhia
Kauj ruam 1
Thawj kauj ruam yog los npaj txhua yam tsim nyog rau kev sib dhos hauv Circuit Court. Nws raug nquahu kom ua raws nraim rau cov qhia tseeb, tab sis yog tias koj tsis tuaj yeem pom lawv, nws tsis tseem ceeb, koj tuaj yeem tso cov nyob ze. Diodes 1N4148 tuaj yeem hloov nrog KD522 lossis 1N4007, IRFZ44 transistor tuaj yeem hloov mus rau IRF730, IRF630 lossis lwm tus zoo sib xws.

Thaum tag nrho cov seem sib sau ua ke, koj tuaj yeem pib tsim cov ntawv luam tawm ntawm lub rooj sib tham uas lub Circuit Court yuav raug muab sib sau. Nws yog tsim los ntawm LUT txheej txheem, vim hais tias nws yog tus qauv pheej yig tshaj plaws thiab yooj yim rau kev ua cov ntawv luam tawm Circuit Court hauv tsev. Daim duab nws tus kheej tuaj yeem kos duab rau hauv cov khoos phis tawm, piv txwv li Sprint Layout, lossis los ntawm tes nrog cov kua roj vanish. Daim duab yuav tsum yog tag nrho rau cov txheej txheem, tsuas yog tom qab ntawd pawg thawj coj yuav tau ua haujlwm. Cov neeg nyob ze yuav tsum tsis txhob khiav mus ze rau ib leeg, txwv tsis pub muaj lub voj voog luv. Tom qab thov ib txheej kev tiv thaiv ntawm kev taug mus rau lub textolite, lub rooj tsavxwm tuaj yeem yog etched. Ua li no, nchuav ib khob dej rau hauv ib lub taub hau yas ntim, nchuav ib diav kua txiv qaub ntawm citric acid thiab ib me nyuam diav ntsev. Peb sib xyaw, muab tso rau ntawm lub rooj tsavxwm, tom qab li 20-30 feeb, cov xeb ntau dhau yuav tawm ntawm lub rooj tsavxwm, thiab txoj kev daws yuav hloov ua ntsuab. Tam sim no txhua qhov seem yog kom tshem tawm cov txheej tiv thaiv nrog cov kuab tshuaj, tho lub qhov, ua kom haum ntawm cov ciav hlau, thiab lub rooj tsavxwm tau npaj txhij.
Kauj ruam 3
Thaum lub rooj tsavxwm yog npaj txhij, koj tuaj yeem muag cov khoom seem. Ua ntej, resistors, diodes raug ntsia rau ntawm lub rooj tsavxwm, tom qab ntawd yog lub zog, thiab lub xeem tab sis tsis tsawg, transistor thiab microcircuit. Nws yog qhov yooj yim tshaj plaws los coj cov xov hlau rau txuas lub load thiab hloov fais fab los ntawm lub davhlau ya nyob twg thaiv. Tom qab ua tiav ntawm kev ua tiav ntawm soldering, nws yog qhov yuav tsum tau kuaj xyuas qhov tseeb kev teeb tsa, ntxuav tawm cov nplaim hluav taws xob uas tseem tshuav thiab lub nplhaib sib txuas rau cov ntu luv. PWM tus tswj hwm pib npaj txhij, koj tuaj yeem txuas nws rau lub zog hluav taws xob, thauj khoom thiab tshawb xyuas kev ua haujlwm.
