Lub kaw lus fais fab Hauv cov tshuab fais fab, cov chaw hloov pauv thiab lwm qhov muaj peev xwm loj, tshuab hluav taws xob muaj zog, DC cov tshuab muaj cov khoom siv hluav taws xob zoo rau kev tiv thaiv kev tiv thaiv, kev tswj xyuas kev ua haujlwm, lub suab nrov, thiab teeb pom kev sib tsoo. Cov hluav taws xob me hluav taws xob Circuit Court yog qhov tseem ceeb tshaj plaws Ib qho ntawm cov tseem ceeb, nws txoj haujlwm ruaj khov thiab txhim khu kev qha ncaj qha ncaj qha rau kev nyab xeeb ntawm lub zog tag nrho. Cov kev txhim kho muaj zog ntawm DC lub zog cov ntaub ntawv kev lag luam tau ua rau txoj kev loj hlob ntawm DC lub zog hluav taws xob kev lag luam xws li kev sib txuas lus fais fab mov, EPS, UPS, thiab lwm yam. Lub hauv paus chaw nres tsheb thiab cov ntaub ntawv chaw tau nce thiab tam sim no nyob rau hauv Suav teb. Txhawm rau kom paub tseeb lub siab qhov yuav tsum tau ua ntawm DC lub zog hluav taws xob, raws li DC Qhov tseem ceeb tshaj DC Circuit Court tej fais fab rau kev khiav hauj lwm thiab tiv thaiv cov khoom sib txuas hauv qhov chaw txuas ntawm lub cav hluav taws xob tau ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov khoom siv thiab ua qhov txwv ntawm qhov xwm txheej nrog nws txhim khu kev qha kev xaiv theem. Rail Transit thiab Hluav Taws Xob Lub Tsheb Lem Tam sim no, Tuam Tshoj' s txoj kev tsheb nqaj hlau nroog hauv nroog yog tsav los ntawm DC system.
Feem ntau ntawm nws cov khoom siv fais fab DC yog muab los ntawm cov muaj zog-silicon rectifiers, thiab cov silicon rectifier Cheebtsam muaj cov kev xav tau qis rau kev ua haujlwm ntau dhau, thiab qhov yuav tsum tau ua rau DC lub zog daim phiaj thaiv kev tiv thaiv yog siab dua. Tshawb xyuas ceev ntawm cov khoom tseem ceeb hauv cov tsheb nqaj hlau thauj mus rau DC-cov khoom hluav taws xob. Nkoj DC Circuit Court tej nkoj nquam yog ib qho tseem ceeb tshaj plaws nyob rau hauv fais fab tub rog tsav nkoj thiab cov tshuab fais fab. Nws tiv thaiv qhov ua yuam kev ntawm lub zog faib hluav taws xob thiab khoom siv hluav taws xob, thiab siv ntau yam kev tiv thaiv kom ntseeg tau tias muaj kev nyab xeeb ntawm lub nkoj' s lub zog xa hluav taws xob thiab khoom siv hluav taws xob.
