1000W 1200W HSI PLUS Inverter

HSI PLUS 1000W 1200W hnub ci inverter hybrid ntshiab sine yoj inverter nrog tsawg zaus

Pulse Width Modulation:

Pulse width modulation yog ib txoj kev tswj hwm analog, uas hloov kho qhov kev tsis sib haum xeeb ntawm lub hauv paus transistor lossis lub rooj vag ntawm MOS raj raws li qhov kev hloov pauv ntawm cov khoom thauj, kom paub txog qhov kev hloov pauv ntawm lub sijhawm hloov pauv ntawm lub transistor lossis MOS raj, thiaj li paub txog qhov kev hloov ntawm cov zis ntawm lub switching tswj fais fab mov. . Nyob rau hauv txoj kev no, qhov tso zis hluav taws xob ntawm lub zog hluav taws xob tuaj yeem khaws cia tas mus li thaum lub sijhawm ua haujlwm hloov pauv, thiab nws yog ib qho cuab yeej zoo heev los tswj cov analog Circuit Court los ntawm kev siv cov teeb liab digital ntawm microprocessor. Siv dav hauv ntau qhov chaw los ntawm kev ntsuas thiab kev sib txuas lus mus rau kev tswj fais fab thiab kev hloov pauv.

Lub hauv paus ntsiab lus ntawm pulse width modulation (PWM): Txoj kev tswj yog los tswj lub on-off ntawm lub switching ntaus ntawv ntawm lub inverter Circuit Court, thiaj li hais tias cov zis davhlau ya nyob twg yuav tau txais ib tug series ntawm pulses nrog sib npaug amplitude tab sis inconsistent dav, thiab siv. cov pulses no hloov lub sine yoj los yog cov mem tes yuav tsum tau. waveform. Ntawd yog, ntau lub pulses yog tsim nyob rau hauv ib nrab lub voj voog ntawm cov zis waveform, yog li qhov sib npaug ntawm txhua tus mem tes yog sine waveform, thiab cov khoom tau txais yog du thiab muaj qee qhov kev txiav txim siab qis. Qhov dav ntawm txhua tus mem tes yog hloov kho raws li qee txoj cai, uas tuaj yeem tsis tsuas yog hloov qhov loj ntawm qhov tso zis voltage ntawm lub inverter Circuit Court, tab sis kuj hloov cov zis zaus.

Hauv PWM waveform, qhov amplitude ntawm txhua tus mem tes sib npaug. Txhawm rau hloov qhov amplitude ntawm qhov sib npaug ntawm cov zis sine yoj, nws tsuas yog yuav tsum tau hloov qhov dav ntawm txhua tus mem tes raws li qhov sib npaug sib npaug. Yog li ntawd, nyob rau hauv AC-DC-AC inverter, lub mem tes voltage tso zis los ntawm lub PWM inverter Circuit Court yog lub amplitude ntawm DC sab voltage.
