Yuav ua li cas txheeb xyuas cov nyhuv calibration tom qab RC tsis raug kaw?

I. Basic hardware parameters verification

Qhov tseeb RC Capacitance divergence: Siv lub siab -precision digital multimeter, sim qhov tseeb capacitance tus nqi ntawm lub kaw lus RC network, thiab xyuas kom meej tias qhov sib txawv ntawm qhov ntsuas ntsuas tus nqi tsawg dua lossis sib npaug li 5%.

Filter cutoff zaus pov thawj: Siv tus qauv teeb liab lub tshuab hluav taws xob kom nkag mus rau qhov kev sim sinusoidal cov cim ntawm qhov sib txawv thiab xyuas tias qhov tseeb lim txiav tawm qhov sib txawv yog 10% ntawm tus nqi teev.

Kev txheeb xyuas qhov cuam tshuam ntawm kev cuam tshuam: Tom qab lim cov thawj zaus cuam tshuam cov teeb liab hauv kev cob qhia, qhov ntsuas qhov attenuation siab dua lossis sib npaug li 20dB, ua tau raws li cov qauv kev cuam tshuam.

II. Dynamic teeb liab kev ua tau zoo xyuas

Kev ntsuas kub ntsuas ncua sij hawm: Kho qhov ntsuas kub sai sai ntawm cov khoom siv thermocouple terminals thiab sau lub sijhawm ncua sij hawm rau qhov ntsuas kub kom ncav cuag qhov ntsuas kub, lees tias Tsawg dua lossis sib npaug li 200ms.

Kev kuaj lub teeb liab ripple: Siv oscilloscope los soj ntsuam qhov ntsuas qhov ntsuas qhov ntsuas kub tom qab lim kom paub tseeb tias qhov siab tshaj plaws ripple - mus rau - tus nqi siab tshaj los yog sib npaug rau 10mV, thiab tsis muaj suab nrov nrov.

Temperature Stability Test: Qhov kub thiab txias tsis hloov pauv li ntawm ± 0.5℃thiab tsis muaj drift tom qab 2 teev ntawm kev ua haujlwm tsis tu ncua -load.

III. Kev lees paub qhov tseeb ntawm kev tsim khoom

Kev ntsuas kub khiav cua sov nkhaus: Pib cov txheej txheem kub khiav cua sov, thiab tsis muaj qhov pom tseeb overshoot hauv cov txheej txheem cua sov (overshoot Tsawg dua lossis sib npaug li 3 degree) thiab tsis muaj oscillation.

Full Load Interference Test: Tag nrho cov siab - lub zog txhaj tshuaj molding tshuab thiab zaus converters nyob rau hauv lub rhiav nyob sib ze tau qhib, simulating qhov siab tshaj plaws cuam tshuam scenario, thiab tsis muaj variation ntawm kub nyeem ntawv.

Cov txheej txheem Adaptability Verification: Tom qab 8 teev ntawm kev tsim khoom tas mus li, cov khoom lag luam tau lees paub tias ruaj khov, thiab tsis muaj qhov ua txhaum xws li cov kua nplaum tsis txaus, nyem, lossis cov cim kev ntxhov siab uas tsim los ntawm qhov ntsuas kub tsis zoo.

IV. Long Term Stability Closed Loop Verification

Lockout Status Check: Tom qab 72 teev ntawm kev ua haujlwm tas mus li, qhov ntsuas kub tswj qhov xwm txheej bar tseem pom "RC Hardware Lock" uas tsis muaj qhov pib rov pib dua cov ntaub ntawv.

Cov ntaub ntawv Archiving: Tag nrho cov ntaub ntawv pov thawj tau muab khaws cia rau hauv cov txheej txheem archive los muab cov qauv ntsuas rau yav tom ntej dynamic hloov kho thaum lub sij hawm calibration.
