Hom kev ua haujlwm tseem ceeb ntawm DC tswj fais fab mov
GVDA tsom rau kev muab DC cov cuab yeej ntsuas thiab cov kev daws teeb meem ntse rau cov neeg siv khoom thoob ntiaj teb
Cov khoom siv hluav taws xob tswj tau yog cov khoom siv hluav taws xob uas tuaj yeem muab cov khoom siv hluav taws xob ruaj khov AC lossis DC fais fab mov rau lub nra, uas yog hais tias, nws tuaj yeem muab faib ua ob pawg, DC tswj fais fab mov thiab AC tswj fais fab mov.
Hom kev ua haujlwm ntawm DC tswj fais fab mov feem ntau muab faib ua peb lub ntsiab lus:
1. Hom rectifier controllable kho cov zis voltage los ntawm kev hloov lub sij hawm conduction ntawm thyristor.
2. Chopping hom, cov tswv yim yog qhov tsis ruaj tsis khov DC voltage, hloov qhov sib piv ntawm qhov sib txuas ntawm qhov hloov mus kom tau ib qho unidirectional pulsating DC, thiab tau txais qhov ruaj khov DC voltage tom qab lim.
3. Hloov hom, qhov tsis ruaj tsis khov DC voltage yuav tsum ua ntej hloov mus rau hauv high-frequency alternating tam sim no los ntawm inverter, thiab ces ib tug tshiab DC tso zis voltage yuav tsum tau tom qab DC stabilized fais fab mov, transformer, rectification thiab lim, thiab pub rov qab rau tswj kev khiav hauj lwm zaus ntawm lub inverter. Txhawm rau ua tiav lub hom phiaj ntawm qhov tso zis ruaj khov DC voltage.
