A okwanira transformerless mphamvu cholinga, makamaka, mfundo ya ntchito zida za

amapereka mphamvu kwa makompyuta zochokera transformerless madera olumikizidwa kwa maukonde (mu Ndipotu pulsed mphamvu kotunga). Iwo yodziwika ndi mtengo wapatali wa dzuwa, mbali yaing'ono ndi otsika kulemera. Komabe, mwa kundipatsako transformerless mphamvu ali ndi chidwi drawback - spikes phokoso kungasokoneze pa ziwembu ma PC zina ndi zipangizo zina ogula zamagetsi. Motero aliyense mankhwala ngati akudutsa mayeso yaikulu ngakhale mu atomu ndi zipangizo zina. Komanso, thiransifoma zochepa magetsi wagawo ali magetsi kudzipatula ku mbali ya dera magetsi ku mains voteji. Zimenezi zimafuna kugwiritsa ntchito miyeso wapadera chitetezo pa kukonza nkhani.

Transformerless mphamvu okwanira: waukulu zinchito mbali

zida tichipeza zigawo izi:

- zopezera rectifier;

- EMC fyuluta;

- choyambitsa dera;

- capacitive fyuluta;

- voteji Converter zochokera zimachitika mphamvu inverter;

- dera kupoletsa ndi linanena bungwe voteji;

- kulamulira dera;

- kupanga ndi kufalitsa dera zizindikiro ndemanga dera ulamuliro.

zinthu zina

Malinga ndi chitsanzo ndi magwiridwe, ndi thiransifoma zochepa mphamvu kotunga zikuphatikizapo madera zina monga yang'anira liniya mu apawokha kapena Integrated mawonekedwe, zimamuchulukira chitetezo athandizira ndi linanena bungwe voteji ndipo panopa, komanso yimitsira dera. Komanso, nawonso mphamvu zingaphatikizepo circuitry kwa kupoletsa ulamuliro chizindikiro kuti kupereka ofananira chipangizo dera chakudya.

Mfundo ntchito

Kusintha mphamvu katundu konsekonse kwa DC voteji kutembenuka imagwiridwa patatu athandizira voteji. Choyamba, kudzatha ndi ankawachotsera. Chifukwa ndi DC voteji, kenako aumbike mwa nyemba amakona anayi pa mlingo wa makumi kilohertz. Kenako, nyemba akusinthika ndi mbali yachiwiri ndi koyefishienti chogwirizana, ndipo akupita rectification ndi kusalaza. Mbuyache mfundo transformerless magetsi voteji converters ndi ofunika kwambiri, ndipo makamaka mphamvu zawo Unit (mkulu-mphamvu siteji linanena bungwe). masiteji izi zikhoza kugawidwa mu umodzi-zinatha ndipo Kankhani-chikoka.

katundu chosinthika mphamvu

Kusintha linanena bungwe voteji makhalidwe zipangizo transformerless zambiri anagwiritsa ntchito njira za Kugunda m'lifupi kusinthasintha mawu, lomwe ndi kusintha nthawi zimachitika, ndipo akuima therebetween. Pamene izi pafupipafupi kusintha amakhalabe sichinasinthe. Kubverana zedi amenewa nthawi ya zimachitika ndipo perekani, zimadalira voteji linanena bungwe. Izo basi anasintha kukhala linanena bungwe voteji mu mtengo mwadzina.
