Qhov Tseem Ceeb ntawm Prestazione E Metodi di Prova Della Corrente Regolata
Cov ntsuas kev ua haujlwm ntawm DC cov khoom siv hluav taws xob tau muab faib ua ob hom: ib qho yog cov zis voltage, thiab cov zis tawm tshiab, thiab cov zis voltage cov kev cai, thiab lwm yam. Another type is quality indicators, which are used to measure the stability of the output DC voltage, including voltage stabilization coefficient (or voltage regulation rate), output resistance (or current regulation rate), ripple voltage (surrounding and random drift), and temperature coefficient.
(1) Voltle Volage: lub AC Voltage sib sib zog superimposed ntawm cov zis hluav taws xob. Kev saib nws lub ncov mus rau cov nqi ncov nrog tus oscilloscope feem ntau nyob rau hauv millivolt ntau. An Millivolt 'Meter kuj tseem siv tau los ntsuas nws tus nqi zoo, tab sis txij li thaum lub ripple tsis yog sine yoj, muaj ib qho yuam kev. Feem ntau, cov ripple vp-p ntawm DC cov khoom siv hluav taws xob tsawg dua lossis muaj sib npaug rau 10mv.
(2) Voltage stabilization coeffilization coeffility: nyob rau hauv cov xwm txheej ntawm constant load tam sim no thiab qhov kev hloov siab hloov ntawm cov zis hluav taws xob, uas yog:
(3) Cov kev cai voltage txwv: kev hloov pauv hloov pauv cov zis hluav taws xob thaum cov tswv yim hloov pauv los ntawm ± 10%. Qhov ntsuas hluav taws xob coefficients thiab voltage kev tswj hwm tus kheej ob qho kev qhia ntawm cov kev hloov voltage, yog li tsuas yog ib qho ntawm lawv yuav tsum tau kuaj.
(4) Tso Tawm Tawm thiab Kev Cai Tswj Tam Sim No
Cov zis tsis dhau yog qhov zoo ib yam li cov zis tiv thaiv ntawm lub zog hloov pauv ntawm cov zis tam sim no thaum cov tswv yim voltage tas li. Txoj Cai Kev Cai Tam Sim No: Qhov kev hloov pauv hloov pauv voltorage tsim tawm thaum cov zis tam sim no hloov los ntawm {}} rau tus nqi siab tshaj plaws. Cov zis tsis kam thiab kev tswj hwm tam sim no qhia qhov kev cuam tshuam nrog cov kev hloov pauv tam sim no ntawm cov zis hluav taws xob, yog li tsuas yog ib qho ntawm lawv yuav tsum tau kuaj.
