Kusanzwisisana Kungani Kwemagetsi Kwaunoziva?

Chii chinonyanya kukosha cheEMI circuit?

Basa reEMI circuit nderekusefa marudzi ese ezviratidzo zvekupindira kubva pa power grid uye kudzivirira high-frequency interference power grid inoumbwa ne power switch circuit. EMI chikamu chakakosha cheCCC certification.

Kusanzwisisana kwemagetsi:

1: Simba remagetsi rakatarwa rinofanira kunge riri diki? Kushandiswa kwesimba kunoenderana nekushandiswa kwesimba repuratifomu, uye hakuna chekuita nehukuru hwesimba remagetsi. Kana simba remagetsi riri diki zvakanyanya, harizokwanisi kutanga.

2: Kupa magetsi kuti usarudze module yakazara? Boka rese remodule rinongotarisa waya chete, manejimendi yemitsetse iri nyore, uye zvakanaka kana zvakaipa hazvina chekuita nazvo.

3: Kusanzwisisa mwero wekuchinja, magetsi akajairika, ane 450W. Kuburitsa kwecan 450W, 80% mwero wekushandura zvinoreva kuti komputa inoshandisa 450W, simba rese rinoshandiswa nehome meter i450÷80%=562W

4: Sarudza simba rakanyanya kuyera re2000W, diki diki? Hapana hukama hwakananga pakati pesimba remagetsi nesimba rakayera. Simba remagetsi rinofanira kunge rakanangana nerudzi rwakati uye modhi yakati, kwete nekutarisa maparamita epamusoro.

Chinja voltage yeAC (AC) yakakwira kuita voltage yemagetsi yakananga (DC) yakaderera inodiwa kuti PC ishande nekushandisa tekinoroji yekuchinja mafrequency akawanda.

Unoziva zvakawanda sei nezve mashandiro emagetsi?

1: Ndeipi musimboti wekutanga wekushanda kwemagetsi?

Chinja voltage yepamusoro yeAC (AC) kuita voltage yakaderera yemagetsi (DC) inodiwa kuti ishande

Kushanda kwePC uchishandisa tekinoroji yekuchinja-chinja mafrequency akawanda.

2. Ndeipi nzira yekushanda kwemagetsi?

Kana mains apinda mumagetsi, anotanga apinda nepachoke coil necapacitor filter kuti abvise high frequency clutter uye interference signal, uye ozopfuura nepakugadzirisa nekusefa kuti awane high voltage direct current. Zvadaro nepa switching circuit kuenda ku high frequency pulsating DC, uye ozotumira high frequency switching transformer step-down. Chikamu che high-frequency AC chinozosefa, kuitira kuti output yekupedzisira ive low-voltage DC power yakachena yekombuta.

3. Basa guru reEMI circuit nderei?

BASA reEMI circuit nderekusefa marudzi ese ezviratidzo zvinokanganisa zvinobva pa power grid, uye kudzivirira grid yemagetsi inofambisa ma frequency akawanda inoumbwa ne power switch circuit.

EMI chikamu chakakosha cheCCC certification.
