Kuthiwani uma i-adaptha yamandla ikhala

I-adaptha yamandla, esebenzisa umsindo omkhulu kakhulu othi "squeak", ukuphazamisa isimo sokusebenza somthengi.

Inqubo yokulungisa: Ngokuvamile, kuvamile ukuthi i-adaptha yamandla ibe nomsindo omncane wokusebenza, kodwa uma umsindo ucasula, lokho kuyinkinga. Ngoba i-adaptha yamandla ku-switching transformer kuphela, noma indandatho kazibuthe ikhoyili kanye nekhoyili phakathi kwegebe elikhulu kuzodala "ukukhiya". Ngemva kokukhipha i-adaptha yamandla, thinta kancane ingxenye yekhoyili kuma-inductors amabili ngaphandle kokunikezwa kwamandla. Uma ingazizwa ikhululekile, ungaqiniseka ukuthi umsindo osebenzayo we-adaptha yamandla uvela ku-switching transformer.

Indlela yokuqeda umsindo "we-squeak" wokushintsha i-transformer ngesikhathi sokusebenza imi kanje:

(1) Phinda ushisele amajoyinti e-solder axhuma izikhonkwane ezimbalwa ze-switch transformer kanye nebhodi lesifunda PRINTED ngensimbi yokudambisa kagesi. Uma ushisela, cindezela i-switch transformer ebhodini lesifunda ngesandla, ukuze phansi kwe-switch transformer kusondelene nebhodi lesifunda.

(2) kumongo we-switch transformer kanye nekhoyili efakwe phakathi kwepuleti lepulasitiki elifanele noma elivalwe nge-polyurethane enamathelayo.

(3) Ku-switch transformer kanye nebhodi lesifunda phakathi kwephedi libe yiphepha eliqinile noma ibhodi lepulasitiki.

Kulesi simo, i-switch transformer isusiwe ebhodini lesifunda futhi "i-squeak" yaqedwa ngokusebenzisa enye indlela.

Ngakho-ke, ekuthengeni i-adaptha yamandla, ukulawulwa kwekhwalithi ye-adaptha ye-adaptha yamandla nayo iyadingeka kakhulu, okungenani ingasindisa ukungahambi kahle okuningi!
