Turukan Mataimakawa Votaji Da Ba Taka

Mataimakawa votaji da ba taka yana fiye da mataimakawan votaji na kimiyya a kan zinariya, hanyoyi, inganci da kuma ci gaba. Mataimakawa votaji da ba taka ana haɗa da biyu ne. Suna su;

• Mataimakawa Votaji na Servo

• Mataimakawa Votaji na Amplifier Mai Tsirriyar Karamin Magana

An bayyana turukan mataimakawa votaji da ba taka a cikin wannan bayanai masu zabiri;

Mataimakawa Votaji na Servo

Babban muhimmanci na mataimakawa votaji na servo shine amfani da amplidyne. Amplidyne shine wata amplifier na kimiyya da ya yi amfutar sinal. Yankin ya ƙunshi mai tsirriyar karamin magana mai yawa da aka sa shi daga ɗaya na alternator da kuma mai tsirriyar karamin magana mai yamma da aka ɗaukarsa a kan amplidyne.

Akwai mai tsirriyar karamin magana mai yamma da amplidyne da aka sa shi daga mota na DC da aka haɗa zuwa abubuwan da suka. Mai tsirriyar karamin magana mai yawa ya ƙunshi jiki mai tsirriyar karamin magana mai yawa da aka haɗa zuwa field winding na alternator.

Yadda Mataimakawa Votaji na Servo Ya Yi Aiki

Transformer na potential ya ba sinal da ke mafi girma a kan sinal na output ta alternator. Ayanayin terminal na output ta alternator suna haɗa zuwa amplifier na electronics. Idan yake iya a kan votaji na output ta alternator, amplifier na electronics ya bazu votaji zuwa amplidyne. Output ta amplidyne ya bazu votaji zuwa control field na amplidyne da kuma ya ɗaukar field na mai tsirriyar karamin magana mai yamma. Saboda haka, mai tsirriyar karamin magana mai yamma da mai yawa suka ɗaukar current na excitation ta alternator.

Mataimakawa Votaji na Magnetic Amplifier

Wata muhimman abu a cikin magnetic amplifiers shine coil mai tsirriyar karamin magana da akwai additional winding da aka ɗaukarsa a kan direct current (DC). Wannan additional winding ya haɗe ɗaukar power AC na mafi girma a kan power DC na yawa. Core na steel na regulator ya ƙunshi biyu windings na AC da suke musamman, wadannan suna ake kira load windings. Wadannan windings na AC za su iya haɗa zuwa series ko parallel, da amma a cikin halayen da suke suka haɗa zuwa load.

Configuracin da aka haɗa zuwa series winding na iya amfani a lokacin da an bukatar response na ƙarin lokaci da mafi girma a votaji, inda parallel winding setup na iya amfani a fannon da an bukatar response na ƙarƙashin lokaci. Control winding ya ƙunshi power na DC. Idan ba da current na load winding, winding na AC ya ba da impedance da inductance mafi girma a source na AC. Saboda haka, alternating current na bayan a taka don load ya ƙasa da high inductive reactance, wanda ya ƙare votaji na load da ƙarin.

Idan a ɗaukar votaji na DC, flux na DC ya ƙare core, wanda ya ƙare ita zuwa saturation. Wannan ya ƙara inductance da impedance na windings na AC. Amma idan current na DC a kan control winding yake ƙara, alternating current na field winding yake ƙara. Saboda haka, adjustment na ƙarin lokaci a kan magnitude na current na load ya ƙare variation na ƙarin lokaci a kan votaji na load.
