Kungani sidinga umvikeli yokwanda?

Enye inqubo operation evamile zobuchwepheshe kuyinto isitebele ugesi. Ushintsho voltage in inethiwekhi supply kungathinta ngokuhlolisisa ukusebenza lisebenze yasendlini. izingxenye semiconductor ukunikeza amathuba angeziwe sokuthuthukiswa kumadivayisi ahlukahlukene. Ngeshwa, nozwelo ezimweni yokusebenza kanye nezidingo ukwelashwa ngokucophelela bakuphi. Omunye amadivayisi okungase ukuvikela electronics ekulimaleni ngenxa yamandla yokwanda kwama noma amazinga aphezulu umsindo imizwa inethiwekhi ukuthengisela, kuyinto isihlungi inethiwekhi. Alwa ngayo umsebenzi walo futhi bandisa ukuphila insimbi.

Ake ubone ngeso lengqondo amandla supply futhi sibheke indlela izinhlobo ezahlukene abathengi kuthinte izilungiselelo zalo. Futhi njengendlela lemifanekiso inethiwekhi kusindisa zobuchwepheshe ekulimaleni? Kahle kahle, voltage supply kuyinto sinusoid. Kuyinto njalo wamanje yayo (amplitude) futhi imvamisa. Ngeshwa, lapho abathengi ezinamandla kagesi kokuba izinhlobo ezihlukahlukene zezindwangu ezingaba ukuphazamiseka, okuyinto kungalimaza empahleni ebucayi.

Ekuphileni kwethu kwansuku zonke ezinjalo "enomsindo" zikagesi zihlanganisa vacuum cleaner omkhathi, amafriji noma emoyeni isimo. Yilapho umsebenzi noma ezinye izinhlobo motors indlela, qinisekisa ukuthi ukuphazamiseka kokulinganisela inethiwekhi supply. Lokhu kungenxa isusa ku ukuxubha noma ngesizathu esithile. Ngisho ukusebenza ojwayelekile wethuka woma kagesi zingaphazamisa, isibonelo, umsakazo abamukelayo. Ngamanye amazwi, uma nge umthwalo exhasa futhi sekhefu elifushane i wesifunda kagesi (njengoba kunjalo motor emabhulashini) ukuphazamiseka ukuwa ku amapayipi supply. Ziyakwazi iDemo overvoltage pulses. Yokwanda umvikeli ngqó, usethe ukubhekana anomalies enjalo.

Kodwa inkinga akuyona kuphela motors kagesi. Ngisho zohlobo olulodwa kakhulu amadivayisi "ezinomsindo" nawo ngokwawo electronics zanamuhla: amathelevishini stereos, amakhompyutha, njll It kuvela ukuthi umvikeli yokwanda uyakwazi ukuvikela electronics ekulimaleni, okuyinto ngokwaso futhi kudala kwezimo ezingezinhle ngomsebenzi wabo. Iqiniso lokuthi amadivayisi yesimanje yakhiwa ukushintsha amandla kagesi, omsebenzi wakhe ihlobene ukuvama 1000 Hz noma ngaphezulu. Njengoba emnyango amadivayisi abanjalo bangabaphostoli transformers kokuba inductance ethile, bese kube nokuphazamiseka okwenzekile.

Ziyakwazi kulula ukubona nge oscilloscope. Ungakwazi ukuqoqa yokwanda umvikeli encane ngezandla wakho ukuqinisekisa ukusebenza kwe-uhlelo lwayo lokusebenza. Kuyinto ngokwanele ukudala i inductance, elizovimba ukudlula ephezulu imvamisa umsindo amapayipi supply. Ngenxa yale njongo umane ukugoqa inombolo ethile ematfuba wire, isibonelo, izimpawu phezu thunga ferrite indandatho kanye solder ke zilandelana kuya wesifunda okuphakelayo computer. Nge ukwanda inductance (inombolo ematfuba) ungabona kwi oscilloscope ukuthi ukuphazamiseka siyaphela kancane kancane.

Okwamanje, kunezinhlobo inqwaba inethiwekhi nezihlungi ahloselwe ngokukhethekile ukusebenza izinhlobo ezahlukene umthwalo. Isibonelo esihle kulokhu kungaba Pilot umugqa lemifanekiso, okuyinto has ukusebenza kakhulu.
