Dab tsi yog hom AC stabilized fais fab mov?
Hais txog cov qauv thiab hom kev tswj fais fab, feem ntau lawv tuaj yeem muab faib ua plaub pawg. DC, AC, inverter thiab hloov cov khoom siv fais fab. Rau cov plaub yam sib txawv ntawm cov khoom siv fais fab. Txawm hais tias lawv txoj kev ua haujlwm thiab cov ntsiab lus muaj qee qhov sib xws, lawv kuj muaj ntau qhov sib txawv. Peb ntu hauv qab no yuav qhia meej txog plaub yam qauv sib txawv thiab cov khoom siv hluav taws xob tswj hwm.
Thawj qeb yog AC tswj fais fab mov. AC tau muab faib ua ib-theem thiab peb-theem tswj fais fab mov, thiab tseem tuaj yeem muab faib ua kev sib cuag thiab tsis sib cuag tswj fais fab. Hauv kev siv tswv yim, nws tuaj yeem raug sau tseg rau hauv cov hauv qab no feem ntau siv AC stabilized fais fab mov faib faib:
① Ferromagnetic resonance AC voltage stabilizer. Nws muaj ib tug saturable choke thiab coj capacitors thiab muaj qhov tsis tu ncua voltage volt-ampere yam ntxwv.
②Magnetic amplifier hom AC voltage stabilizer. Lub tshuab hluav taws xob sib nqus thiab lub tshuab hluav taws xob autotransformer tau txuas nrog hauv cov koob, thiab cov hluav taws xob hluav taws xob tau siv los hloov qhov impedance ntawm lub tshuab magnetic amplifier kom stabilize cov zis voltage.
③ Sliding AC voltage regulator. Cov zis voltage yog stabilized los ntawm kev hloov txoj hauj lwm ntawm lub transformer zawv zawg sib cuag.
④ Inductive AC voltage stabilizer. Los ntawm kev hloov cov theem sib txawv ntawm theem nrab thiab thawj qhov hluav taws xob ntawm lub transformer, cov zis AC voltage yog stabilized.
⑤ Thyristor AC voltage regulator. Siv cov thyristors ua cov khoom siv hloov hluav taws xob. High stability, ceev teb thiab tsis muaj suab nrov. Tab sis nws yuav ua rau muaj kev cuam tshuam rau cov khoom siv sib txuas lus thiab cov khoom siv hluav taws xob. Tom qab xyoo 1980s, peb yam tshiab ntawm AC stabilized fais fab khoom tau tshwm sim: them nyiaj AC voltage stabilizers. CNC thiab stepper AC voltage regulators. Purified AC voltage regulator. Nws muaj kev sib cais zoo thiab tuaj yeem tshem tawm qhov cuam tshuam siab tshaj plaws ntawm daim phiaj hluav taws xob.
Qhov thib ob loj tshaj plaws yog DC tswj fais fab mov:
Kuj tseem hu ua DC voltage regulator. Feem ntau ntawm nws lub hwj chim mov voltage yog AC voltage. Thaum qhov voltage ntawm AC fais fab mov voltage los yog cov zis load kuj hloov, qhov ncaj qha tso zis voltage ntawm tus regulator yuav nyob twj ywm. Cov tsis muaj voltage regulator muaj xws li voltage stability, ripple coefficient thiab teb ceev.
Qhov thib peb yog inverter tswj fais fab mov
Lub npe hu ua inverter tswj fais fab mov kuj tseem hu ua qhov sib txawv zaus fais fab mov. Qhov sib txawv zaus fais fab mov no yog tswj los ntawm 16-ntsis Motorola processor, high-frequency PWM tsim, thiab tsav los ntawm imported Mitsubishi 1GBT. Cov efficiency nce mus txog ntau tshaj 85%. Cov lus teb yog ceev. Rau 100% kev tshem tawm / thauj khoom, lub sij hawm teb voltage stabilization yog nyob rau hauv 2ms. Qhov sib txawv zaus fais fab mov no muaj zog tshaj qhov muaj peev xwm, thiab tam sim no tuaj yeem tiv taus 300% ntawm cov ntsuas tam sim no. Lub waveform yog ntshiab, lub zaus yog siab thiab ruaj khov, thiab tsis muaj interfering magnetic waves (EMI, EMC) yog tsim. Cov khoom siv hluav taws xob sib txawv tsis yog tsuas yog cov khoom siv hluav taws xob zoo tshaj plaws rau R & D, chav kuaj thiab ntsuas chav, tab sis kuj yog cov qauv hluav taws xob rau EM / EMC / kuaj kev nyab xeeb.
Qhov thib plaub yog hloov pauv tswj fais fab mov
Daim duab schematic thiab sib npaug schematic thaiv daim duab ntawm kev hloov hluav taws xob tswj hluav taws xob yog tsim los ntawm tag nrho-yoj rectifier, lub raj hloov V, lub teeb liab excitation, lub freewheeling diode Vp, lub zog cia inductor thiab lim capacitor C. Qhov tseeb, Lub hauv paus tseem ceeb ntawm kev hloov hluav taws xob tswj hluav taws xob yog DC transformer.
Kuj tseem muaj cov lej tswj hluav taws xob ruaj khov hluav taws xob:
CNC tswj fais fab mov: Nws kuaj cov zis ntawm cov khoom siv los ntawm qhov chaw soj ntsuam, thiab sib piv thiab xyuas qhov tam sim no voltage nrog cov ntsuas hluav taws xob. Yog tias qhov sib piv yog tus nqi tsis zoo, cov ntaub ntawv raug xa mus rau qhov chaw ua haujlwm hauv nruab nrab (CPU), thiab lub chaw ua haujlwm hauv nruab nrab ua kom muaj qhov sib ntxiv. Cov lus txib. Nyob rau tib lub sijhawm, qhov chaw kuaj pom seb puas yog lub semiconductor qhib lossis kaw. Tom qab paub tseeb tias nws yog lawm, lub hauv paus processor teeb tsa qhov kev hais kom ua kom muaj zog los tswj cov kev ua haujlwm semiconductor, yog li ncav cuag tus qauv ntsuas hluav taws xob. Yog tias tus nqi yog qhov zoo, lub hauv paus processor yuav muab cov lus txib txo qis, thiab tag nrho cov txheej txheem digital tsuas yog siv sijhawm 0.048 vib nas this.
