Ua hauj lwm txoj cai ntawm kev hloov ua feem ntau:

Higher transformer yog qhov tseem ceeb tshaj plaws ntawm kev siv hluav taws xob pauv. Switching fais fab mov feem ntau yog siv tau ib nrab-choj faiv fab hloov tshiab Circuit Court. Thaum ob qhov kev sib txuas ntawm transistors tig rau sab tig los ua 100 kHz siab zaus pulse yoj, thiab tom qab ntawd los ntawm high-frequency transformer mus rau theem-down, output low-voltage alternating tam sim no, qib siab zaus transformer winding kauj lem piv txiav cov zauv voltage. Peb qhov sib txawv ntawm cov khoom siv hluav taws xob feem ntau muaj nyob rau hauv lub nruab nrab ntawm tus qauv hluav taws xob feem ntau: lub tshuab hluav taws xob tseem ceeb, lub tsav tsheb thiab lub chaw txua hluav taws xob (qhov chaw nres tsheb) inch (qhov siab) yuav tsum tsis pub tsawg tshaj 200 W zog. 35 hli thiab lub cav xa mus rau lub cav, thaum lub hwj chim tsis pub tshaj 300W, qhov sib npaug ntawm cov hlau nplaum yog 16 hli.

Txoj haujlwm ua haujlwm ntawm kev ua haujlwm yog:

Ib lub tshuab transformer yog ib qho cuab yeej ua rau hloov ua tam sim no hloov tam sim no, tam sim no thiab impedance. Thaum alternating tam sim no siv rau tus thawj kauj, ib qho hloov tam sim no yog generated hauv cov tub ntxhais (los yog cov tub ntxhais) kom voltage (los yog tam sim no) yog raug yuam ua rau theem coil. Lub tshuab ua hluav taws xob muaj cov tub ntxhais hlau (los yog cov tub ntxhais) thiab cov pa co. Cov kauj muaj ob los sis ntau dua. Lub zog ntawm nruab nrab lub hwj huam khoom yog hu ua tus thawj kauj, thiab lwm qhov sib tw hu ua secondary coil.

Cov neeg siv khoom siv hluav taws xob ntau lub zog ua hauj lwm ntau tshaj plaws (10 kHz fais fab roj teeb) inverter welding tshuab raws li lub siab inverter zog transformer raws li cov hauj lwm zaus siab los yog qis, yuav faib ua ob peb qib: 10 kHz-50 kHz 50 kHz 100 kHz 100K Hz 500kHz 500kHz 1 MHz 1 MHz saum toj. qhov ua haujlwm tsawg kuj tsawg, thiab qhov sib kis ntawm tus neeg mob sib kis tsawg, thiab qhov ua haujlwm ntau yog qhov siab.
