Switching zog mov

Hloov cov hwj huam mov yog ib hom hwj huam uas siv hluav taws xob niaj hnub siv hluav taws xob los tswj cov kev sib pauv ntawm lub sij hawm thaum tus tes hloov mus thiab tawm, thiab tswj lub qhov tso zis hluav taws xob ruaj khov. Lub hwj huam hloov hluav taws xob yog feem ntau yog tsim los ntawm kev sib tsuam dav hlau mem tes (PWM) tswj IC thiab MOSFET. Muab piv rau cov khoom siv hluav taws xob, hloov cov khoom siv fais fab nce nqi raws li cov zis muaj zog, tab sis cov kev nce qib sib txawv. Tus nqi hluav taws xob txaus siab tshaj qhov hloov ntawm lub hwj huam ntawm ib qho zis tso tawm qhov taw tes, uas yog hu ua tus nqi them rau kev hloov. Nrog txoj kev loj hlob thiab kev tsim kho ntawm kev siv hluav taws xob tshuab hluav taws xob, kev siv lub tshuab fais fab kev lag luam los kuj tseem niaj hnub tsim kho. Qhov kev siv nyiaj qhov kev hloov no nce mus rau qhov qis kawg ntawm cov hluav taws xob, uas yog muab qhov chaw dav rau kev hloov cov khoom siv fais fab.

Qhov siab hloov ntawm lub hwj huam mov yog qhov kev taw qhia ntawm nws txoj kev loj hlob, thiab qhov siab ua rau lub hwj huam hloov qhov me me.

Daim ntawv thov kev hloov khoom siv fais fab rau ntau yam kev siv, tshwj xeeb tshaj yog hauv kev siv cuab yeej technology, tau nce qib miniaturization thiab txav tau cov khoom siv high-tech. Tsis tas li ntawd, kev tsim kho thiab kev siv cov khoom siv hluav taws xob hloov yog qhov tseem ceeb ntawm kev txuag lub zog, kev txuag kev tiv thaiv thiab kev tiv thaiv ib puag ncig. Lub zog hluav taws xob siv hluav taws xob cov khoom siv yog cov diodes, IGBTs thiab MOSFETs. SCR muaj tsawg tus ntawm daim ntawv sau npe nyob rau ntawm lub hwj huam hloov khoom siv hluav taws xob thiab cov pib mos muag pib. Tus tsav GTR yog qhov nyuaj, qhov hloov zaus yog tsawg, thiab nws maj mam hloov los ntawm IGBT thiab MOSFET.
