Itshaja ayinazo iipali ezilungileyo nezingalunganga? Inyaniso ityhiliwe

Ingaba itshaja inazo iipali ezivumayo nezingalunganga?
Impendulo yile: kuxhomekeke kuhlobo lwetshaja.

1. Itshaja yeDC yesiNtu (enjengetshaja{1}}engqukuva yomlomo):

Olu hlobo lwetshaja ludla ngokuba neepali ezicacileyo nezingalunganga. Umzekelo, umbindi wetshaja endala yefowuni ephathwayo u-positive (+) kwaye umsesane wangaphandle awunayo (-). Ukuba iplagwe ngendlela engalunganga, inokubangela umonakalo kwisixhobo.

2. Itshaja yojongano lwe-USB (efana ne-USB{1}}A/USB-C):

Ujongano lwale mihla lwe-USB ngobulumko ichonga i-polarity ngokusebenzisa iiprothokholi, ngaphandle kokwahlula phakathi kweepali ezilungileyo nezingalunganga. Ukuthatha i-USB-C njengomzekelo, izikhonkwane zayo ezingama-24 zixhasa unikezelo lombane olumacala omabini kwaye inokusebenza ngesiqhelo nokuba iplagwe ngendlela engalunganga (jonga kwi-USB{3}}ukuba isemgangathweni).

3. Itshaja engenazingcingo:

Ayiyo polar ngokupheleleyo, ixhomekeke kwi-electromagnetic induction ukuhambisa amandla, kodwa indawo yekhoyili kufuneka ilungelelaniswe.

 

Kutheni ezinye iitshaja kungafuneki zahlule phakathi kweepali ezilungileyo nezingalunganga?

1. Ulawulo lwetshiphu olukrelekrele:

Umzekelo, i-chip ye-PD yokutshaja ngokukhawuleza iya kulungelelanisa ngokuzenzekelayo isalathiso sangoku ukunqanda iimpazamo ze-polarity (umzekelo, i-iPhone 12 kunye neemodeli ezingaphezulu zixhasa i-20W PD ukutshaja ngokukhawuleza).

2. Uyilo lwesakhiwo somzimba:

I-USB-ujongano lweC lwamkela uyilo olulingeneyo, kwaye abafowunelwa beeplagi zangaphambili nangasemva ziyahambelana. Ngokwedatha yeKhomishini yaseYurophu ngo-2022, izixhobo ze-USB-C zinciphisa inkunkuma yombane ngeetoni ezili-11,000/ngonyaka ngenxa yokuhambelana.

 

Ukungaqondi kakuhle kwabasebenzisi kunye neengcebiso zokhuseleko

1. Ukungaqondi:

- "Zonke iitshaja zinokuxutywa" → Ukungahambelani kweVoltage/protocol kungonakalisa ibhetri (njengentloko ye-9V yokutshaja ngokukhawuleza ngesixhobo esiyi-5V).

- "Ubuchule bokutshaja okungenangcingo buphantsi" → Umgangatho wamva nje we-Qi2 osebenzayo ungaphezulu kwe-80% (xa kuthelekiswa ne-90% yokutshaja ngeengcingo).

2. Iingcebiso zokhuseleko:

- Sebenzisa iitshaja zoqobo okanye eziqinisekisiweyo (ezifana nesiqinisekiso seMFi).

- Kuphephe ukusebenzisa iingcingo ezonakeleyo ukunqanda iisekethe ezimfutshane.

Isishwankathelo: I-polarity yetshaja iyatshintsha ngenxa yophindaphindo lobuchwepheshe. Xa ukhetha, kufuneka ubeke ingqalelo kuhlobo lojongano kunye nokuhambelana kwesixhobo ukuhlawulisa ngokufanelekileyo nangokukhuselekileyo.
