Lub hauv paus ntsiab lus ntawm DC Power Supply Voltage Adjustment Module
DC fais fab mov yog ib qho khoom siv tseem ceeb hauv kev lag luam hluav taws xob, xws li kev lag luam hluav taws xob hloov hluav taws xob, nws yog siv los ntsuas qhov ntsuas hluav taws xob ntau ntawm cov khoom siv hluav taws xob hloov thiab thaum kawg paub meej cov lus qhia tshwj xeeb.
DC fais fab mov plays lub luag haujlwm tseem ceeb hauv kev faib hluav taws xob, yog li dab tsi yog lub hauv paus ntsiab lus ntawm DC fais fab mov voltage hloov?
Nyob rau hauv lub DC fais fab mov voltage hloov module, lub hloov raj yog tsim los ntawm teb cov nyhuv transistors kom ua tiav cov zis tam sim no. Txij li thaum tus tsim xav tau Iomax=5 A, Iomin=0 A, Pm=(Vimax-Vomin)Iomax=(30 × 5)=150 W, yog li ntawd , qhov hloov kho raj hauv Circuit Court no tuaj yeem xaiv TL431.
Kev sib piv thiab kev nthuav dav ntawm Circuit Court siv lub tshuab ua haujlwm ua haujlwm OP07, CPU tswj cov zis hluav taws xob los ntawm DAC, thiab tom qab ntawd cov qauv ntsuas hluav taws xob tsim los ntawm R9, R10, thiab RP ua cov qauv ntsuas hluav taws xob.
Qhov kev tawm tswv yim tsis zoo Circuit Court tsim los ntawm FET, OP07, LM324 thiab sampling Circuit Court tuaj yeem paub lub hom phiaj ntawm kev kho cov zis voltage (stabilizing).
