PWM Mtsogoleri - luso mu circuitry

Development zinthu zamakono ali amadzibisa zingapo: kuchokocha, kusintha kupanga luso lawo, zikamera njira nzeru kamangidwe, etc. madera onsewa akugwirizana wabwino ndi ntchito anafuna ya zida zosiyanasiyana. M'kupita kwa nthawi, pali schematics ndi umisiri watsopano kuti bwino ntchito zida zamagetsi. Mmodzi chipangizo ngati angatchedwe PWM Mtsogoleri. Izi chipangizo yaying'ono, zomwe zimagwiritsa ntchito magwero osiyanasiyana magetsi. Ndi zipangizo ndi njira kutembenuka voteji ndi ntchito bwino mu zosiyanasiyana za magetsi banja, komanso kuntchito.

Modern PWM Mtsogoleri ali mkulu liwiro ndi ntchito chitsanzo kusintha amapereka mphamvu. mfundo zake ntchito ndi wosavuta, izo otembenuka DC voteji mu nyemba amakona anayi a yeniyeni pafupipafupi ndi ntchito mkombero. zikhumbo izi ndi kusamalira mphamvu linanena bungwe gawo zochokera transistors. Ichi chizathandiza ntchito chiwembu osavuta kupeza chosinthika voteji gwero. Nkofunika kuti zamakono, kumene miyeso ndi ofunika. PWM Mtsogoleri analola kulenga yaying'ono pakompyuta zipangizo: Malaputopu, makompyuta, ma TV, etc.

Thiabendazole angagwiritsidwe ntchito kukhazikitsa njira zosiyanasiyana dera kulamulira galimoto liwiro. Lumikizanani nafe mu nkhani iyi angathe kuchitidwa monga magawo osiyana - panopa kapena voteji, zomwe zimasonyeza boma la ulamuliro chinthu. Kungakhale liniya kapena okhota liwiro la injini EMF chizindikiro ku kachipangizo kutentha, etc. Malinga ndi vuto ndi galimoto chizindikiro cha PWM Mtsogoleri ndidzamuukitsa kapena kuchepetsa galimoto liwiro. Chitsanzo chabwino cha ntchito chipangizo ichi kwa zotsimikizira ndi pafupipafupi Converter.

Zipangizo banja zambiri ntchito PWM Mtsogoleri TL494, bwino kutsimikiziridwa ntchito. Chip ali Integrated pafupipafupi jenereta. Izi aipatsa ufulu wina ku chizindikiro kunja. Loyamba- kapena ziwiri sitiroko mode ntchito zimathandiza munthawi yomweyo mwachindunji ndi kukalowa chizindikiro linanena bungwe kuti angagwiritsidwe ntchito kusintha kwinanso. Ambiri, ntchito yake wokometsedwa ntchito mu kotunga kusinthitsa mphamvu. Chiwerengero cha Ine / O akukumana zofunika kale ziwembu ndi ntchito zake.

Kuwonjezera machenjerero muyezo opha ndi PWM ntchito m'madera kamangidwe ka zipangizo nzeru. Ena a iwo, osalephera, posachedwapa anayamba kugwiritsidwa ntchito padziko lonse mafakitale. Ndi thandizo lawo n'kosavuta kusonkhanitsa ulamuliro chiwembu kuti angathe kugwira ntchito zosiyanasiyana.

Ndi chitukuko cha opanga luso zipangizozi tikhoza kunena kuti mu nthawi padzakhala yaying'ono mkulu-liwiro zipangizo zimene kukhazikitsa mfundo pamwamba. Izi adzalola owongolera kukhala ntchito zabwino. zipangizo amenewa akhoza kupikisana ndi analogi awo kapena digito "mukupanga" ndi ntchito mu ulamuliro madera magetsi.
