Cais switching fais fab mov
Kev sib cais hloov hluav taws xob yuav tsum muaj lub tshuab hluav taws xob ntau zaus rau DC-DC hloov dua siab tshiab. Cov tswv yim thiab cov zis yog cais tawm ntawm lub cev los ntawm kev hloov pauv, thiab kev nyab xeeb yuav siab dua.
Lub tswv yim AC lub zog yog kho thiab lim los ntawm tus choj rectifier thiab tom qab ntawd dhau los ua lub zog DC lub zog siab. Lub switching fais fab mov tswj nti ces converts lub high-voltage DC hwj chim rau hauv high-frequency pulsating DC zog thiab inputs nws mus rau lub hauv paus ntawm high-frequency transformer. Los ntawm electromagnetic induction, theem nrab ntawm high-frequency transformer tau Qhov tsawg-voltage pulsating direct tam sim no tau txais, thiab cov low-voltage pulsating direct tam sim no yuav rectified thiab lim kom tau ncaj qha tam sim no.
Lub zog hloov hluav taws xob tswj nti yuav hloov kho qhov zaus hloov pauv thiab lub luag haujlwm lub voj voog raws li qhov tso zis hluav taws xob thiab qhov xav tau tam sim no kom tau txais lub zog hloov pauv ntau dua.
