A na'ura da kuma aiki manufa na wani diode gada rectifier kewaye

Alternating wutar lantarki da aka tuba zuwa DC pulsed ta hanyar amfani da musamman lantarki - diode gadoji. Diode gada rectifier kewaye ne zuwa kashi biyu versions: daya-lokaci da kuma uku-lokaci.

A cikin babban rectifier kashi ne a diode. Fasali, shi ne wani farantin daga cikin semiconductor guntu tare da biyu daban-daban watsin zones. A fasalin ne unilateral nassi na da lantarki, dangane da shugabanci na kwarara.

Tsari da kuma aiki na rectifier diode dangane da fasali na semiconductor pn mika mulki tsakanin zones. Its juriya dogara a kan polarity na waje irin ƙarfin lantarki. A daya harka, shi ne babba, a cikin wasu - dan kadan.

A single-lokaci diode gada

Lokacin da labari - AC ba tare da kalaman irin ƙarfin lantarki a kowane rabin sake zagayowar daga cikin halin yanzu ya wuce ta wata biyu daga diodes da sauran rufe. A sakamakon haka, da fitarwa kewaye kafa wata diode gada rectifier ripple ƙarfin lantarki da ciwon mita biyu sau fi girma fiye da a mashiga.

The uku-lokaci gada kewaye

Wannan kewaye amfani diode rabin-gada rectifiers. The fitarwa ƙarfin lantarki da aka samu tare da karami pulsations.

Yadda santsi daga cikin ripple a straightening ikon?

A ingancin da gãfarta ƙarfin lantarki rage-rage tare da karuwa a cikin pulsation. Don rage shi, tambaya abubuwa, tara makamashi a lokacin da kawota daga rectifier barrantar kan ƙarshe na jerawa.

A cikin zane, a diode gada rectifier da capacitor da alaka a layi daya da na karshe load. Its ajiya iya aiki ne a zabi dangane da kaya halin yanzu. Lokacin da ake ji bugun jini da capacitor da take caji. Tsakanin hatsaisai (lõkacin da suka ba), ko an ba shi da wani irin ƙarfin lantarki load.

A sakamakon da smoothing tace fitarwa ƙarfin lantarki zama ya fi girma, kuma ta halarci tamanin da gãfarta mawadãta darajar.

An manufa ƙarfin lantarki a fitarwa na tace ba za a iya samu saboda da sallama daga cikin capacitor tsakanin hatsaisai. Yawanci, wadannan pulsations ne halatta. Su za a iya rage ta kara capacitance na capacitor.

Idan smoothing inductor da ake amfani, shi an haɗa a jerin tare da load. A hada tace kewaye hada inductors da capacitors.

Construction na diode gada

Mafi sauki na'urar gada da aka yi via raba diodes adhesions. A masana'antu samar monolithic Tsarin da suke da karami a cikin size da kuma rahusa. Bugu da kari, suna dace diodes da irin wannan halaye, da damar su, su yi aiki tare da wannan zafi. Wannan qara aminci da diode gada rectifier kewaye.

A amfani da diode gada daga cikin mutum abubuwa ne da ikon gyara, a lokacin da daya daga cikinsu ya kasa. A taron jama'a kuma yana da da za a maye gurbin gaba daya. Laifinsu a shi ne m, saboda abubuwa suna da kyau dace.
