Voltage Regulation Principple Of Voltage Regulator

Los ntawm lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm lub alternator, peb paub hais tias tus nqi zoo ntawm cov theem electromotive quab yuam generated los ntawm peb-theem winding ntawm lub alternator.

Eφ==CeФn(V)

Ntawm no Ce yog cov txheej txheem tsis tu ncua ntawm lub tshuab hluav taws xob, n yog lub rotor ceev, thiab Ф yog cov sib nqus ncej flux ntawm lub rotor, uas yog hais tias, induced electromotive quab yuam generated los ntawm lub alternator yog proportional rau lub rotor ceev thiab cov hlau nplaum ncej. flux.

Thaum qhov ceev nce, Eφ nce, thiab cov zis voltage UB nce. Thaum qhov ceev nce mus rau qee tus nqi (tso tshaj qhov tsis muaj kev thauj khoom ceev), cov zis hluav taws xob nce mus txog qhov txwv. Txhawm rau ua kom cov zis hluav taws xob UB ntawm lub tshuab hluav taws xob tsis ua raws li qhov nce ntawm kev sib hloov ceev tsuas yog ua tiav los ntawm kev txo cov hlau nplaum sib nqus Ф. Thiab qhov sib nqus ncej flux Ф yog proportional rau lub excitation tam sim no Yog hais tias, txo qhov sib nqus flux Ф yog txo qhov excitation tam sim no Yog.

Yog li ntawd, lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm lub alternator regulator yog: thaum lub ceev ntawm lub alternator nce, lub regulator yuav txo tau cov magnetic flux Ф los ntawm kev txo cov excitation tam sim no Yog hais tias ntawm lub generator, thiaj li hais tias cov zis voltage UB ntawm lub generator tseem unchanged. .

Tiv tauj-hom voltage regulators hloov lub magnetic teb tam sim no Yog hais tias los ntawm qhib thiab kaw cov neeg, tig rau thiab tawm lub magnetic teb Circuit Court, transistor regulators, integrated circuit regulators, thiab lwm yam. siv lub on thiab off, on thiab off ntawm high-power transistors. Sib nqus teb Circuit Court hloov qhov loj ntawm lub magnetic teb tam sim no Yog.
