(1) Voltage regulation coefficient (voltage regulation rate) SU: Nyob rau hauv cov xwm txheej uas lub load tam sim no thiab ambient kub nyob twj ywm unchanged, tus txheeb ze hloov ntawm input voltage (10 feem pua) ua rau cov txheeb ze hloov ntawm cov zis voltage. Qhov me me ntawm SU tus nqi, qhov zoo dua qhov kev tswj qhov hluav taws xob. zoo dua.
(2) Internal resistance (output resistance) rn: When the load current changes, the output voltage of the power supply will also change, and the smaller the change, the better. Internal resistance is used to characterize the power supply's ability to suppress changes in load current. The internal resistance of the power supply is defined as the ratio of the output voltage change of the power supply to the output current change when the input voltage remains unchanged. The smaller the rn, the stronger the suppression ability.
(3) Cov kev cai tam sim no Sl: Cov kev cai tam sim no yog hais txog qhov feem pua ntawm cov kev hloov pauv ntawm cov zis hluav taws xob thaum lub sijhawm thauj khoom tam sim no hloov ntawm xoom mus rau qhov siab tshaj plaws thaum lub zog nkag mus tas li. Qhov me dua Sl, qhov zoo dua cov kev cai tam sim no. . Qhov luaj li cas ntawm cov kev cai tam sim no tseem qhia txog qhov loj ntawm qhov kev tiv thaiv sab hauv rau qee qhov, lawv txhua tus qhia txog lub peev xwm ntawm cov zis hluav taws xob kom ruaj khov thaum lub sijhawm hloov pauv tam sim no. Yog li, feem ntau, tsuas yog ib qho ntawm ob yog siv, thiab qhov taw qhia ntawm kev tiv thaiv sab hauv yog siv ntau zaus.
(4) Ripple coefficient S0: Muaj ripple voltage nyob rau hauv cov zis voltage ntawm lub hwj chim mov, uas yog AC tivthaiv muaj nyob rau hauv cov zis voltage. Yog tias qhov hluav taws xob ripple loj dhau lawm, nws yuav ua rau lub suab nrov rau cov khoom siv suab, thiab yuav ua rau cov duab distortion thiab dov cuam tshuam rau TV. Qhov me dua S0, qhov me dua qhov cuam tshuam ripple.
(5) Kub coefficient Sr: Qhov kub coefficient yog siv los qhia qhov ruaj khov ntawm qhov tso zis voltage kub. Nyob rau hauv cov xwm txheej uas cov input voltage thiab tso zis tam sim no nyob twj ywm tsis hloov, qhov piv ntawm qhov drift ntawm qhov tso zis voltage mus rau qhov kub thiab txias hloov los ntawm kev hloov ntawm qhov kub thiab txias ambient hu ua kub coefficient. Qhov me me, qhov ruaj khov ntau lub zog ua haujlwm 3.
