Adwumayɛ kwan a wɔfa so yɛ wireless charger .

Electromagnetic induction .
Eyi ne ɔkwan a wɔtaa fa so yɛ adwuma wɔ wireless charger mu. Ɛde nnyinasosɛm a ɛfa electromagnetic induction ho no di dwuma de ma current nam electromagnetic induction ntam wɔ primary ne secondary coils ntam, na ɛnam so ma ahoɔden a wɔde kɔ baabi foforo wɔ space range bi mu. Saa kwan a wɔfa so de wireless charger di dwuma yi, wireless charging alliance no ahyɛ ho nkuran.

Radio so asorɔkye .
Radio Wave yɛ ɔkwan a ɛho akokwaw kakra wireless charging kwan so ma wireless charger wɔ saa gyinabea yi. Ne nnyinasosɛm a ɛyɛ adwuma ne sɛ ɛde circuit ketewaa bi a egye kɛse bedi dwuma de agye radio asorɔkye wɔ ahunmu na afei wɔadan anyinam ahoɔden ahoɔden ayɛ no anyinam ahoɔden a ɛyɛ den. Mprempren, nnwumakuw binom aka sɛ wobetumi ahu sɛ ɛlɛtrɔnik mfiri a ɛyɛ nketewa sen fon a ɛwɔ telefon so no yɛ nea wɔde nhama a ɛyɛ hyew a ɛyɛ mita pii na ɛyɛ adwuma.

Electromagnetic resonance .
Eyi yɛ wireless charging technology a ɛda so ara wɔ nhwehwɛmu ne nkɔso fã no mu. Kuw bi a abɔde mu nneɛma ho ɔbenfo bi di wɔn anim wɔ Massachusetts Institute of Technology na ɛsua saa mfiridwuma yi ho ade titiriw. Ɛgyina saa mfiridwuma yi so no, mfiridwumayɛfoɔ a wɔfiri Intel Corporation ahunu sɛ kanea a ɛyɛ watt 60 no hyerɛn wɔ akyirikyiri bɛyɛ mita 1 firi anyinam ahoɔden fibea no ho, na nsɛm a wɔde mena no yɛ adwuma yie 75%. Intel Engineers kaa sɛ botaeɛ a ɛdi hɔ ne sɛ wɔde saa wireless charging technology yi bɛbɔ laptops a wɔasesa no ho ka. Nanso, sɛnea ɛbɛyɛ na wɔadu saa botae yi ho no, ɛho hia nso sɛ wodi anyinam ahoɔden a wɔde di dwuma no ntwitwiridii ne nkɛntɛnso ho dwuma wɔ nneɛma afoforo a ɛwɔ kɔmputa no mu so.
