Rectifier diode - tsananguro parameters uye maitiro

Rectifier diode - wemagetsi kuti kuchinja kugara kuitika ive rakatumbuka ano. Uyu maviri-electrode mudziyo, ine chete chete-nzira (unipolar) yemagetsi conductivity. Rectifier diode kuti semiconductor zvinhu uye kunonzi diode mabhiriji (kana ina diodes chokuita Tsanga yacho yaichekwa vaviri vaviri mune imwe nyaya) yakatsiva ignitron uye Vacuum diode.

The mugumisiro rectification kuti rakatumbuka kuitika uye kuichinja kuva kuchinja zvachose kunoitika panguva semiconductor-metal, simbi-semiconductor kana vanonzi Erekitironi-mugomba kuchinja mune dzimwe crystals (semuenzaniso, nesilicon, germanium, selenium, mhangura oxide). crystals kwakadaro kazhinji zvinoumba hwaro mudziyo.

Semiconductor rectifier diode kushandiswa zvemagetsi, zvemagetsi uye zvemagetsi namano. Kutaura zvazviri, kuswatura - ichi kushandurwa rakatumbuka kuitika (voltage) kuti kuitika mumwe polarity (pulsating DC). Izvi mhando rectification vanoda ari unyanzvi kuti kuvhura nokuvhara nematunhu yemagetsi, nokuchinja uye kuziva miedzo zviratidzo zvemagetsi uye pulses, uye vakawanda zvimwe transformations zvakafanana. Kwakadaro diode Unhu hwakadai waivako, kutsiga parameters, inogona PN junctions havasungirwi kupa kwaari chero chaiwo zvinodiwa.

mudziyo kwakadaro ane zvimwe parameters zvemagetsi uye zvechadenga diodes:

- mberi voltage pa akati ano ukoshi (zvakatorwa avhareji ukoshi) ;

- ruvhesi razvino pane imwe kukosha neizvi voltage netembiricha (avhareji ukoshi) ;

- the amplitude tsika kuti vaifanira bvumidzwa neizvi voltage;

- avhareji kukosha mberi kuitika;

- maitikiro tsika pasina rutapudzo muoti;

- nemishonga.

Rectifier diode rinowanzoshandiswa rakapfupikiswa nyore kunzi rectifier. Sezvo chezvinonhuwira mudunhu, ane mukuru nemishonga kuti kuitika inoyerera muna rimwe divi uye yakaderera kune rikaitika neizvi negwara. Izvi zvinokonzera rimwe kuitika rectification.

In zano akadai diode rectifier, munhu zvakakwana diki Frequency siyana. Uchishandisa kakawanda kuti maindasitiri kushandisa zano rakadaro ane AC kuna DC kutendeuka ndiyo 50 Hz. Muganhu maitikiro anoonekwa pasina kupfuura 20 kHz.

Rectifier diode sezvo wemagetsi inogona kupatsanurwa muzvikwata akawanda maererano paavhareji kukosha kufadza zvakananga uno. Ichi pasi simba diode (0.3 amps), svikiro simba (kubvira 0.3 A 10 A) uye rinorema basa (simba) rectifier diodes (amperes anopfuura gumi).

The chikuru parameters zvakadaro zvemagetsi zvakadai somunhu rectifier diode, uye anofanira kusanganisira uchishandisa siyana nokuda ambient tembiricha (zvinowanzoda anoda kubva -50 kusvika +130 Celsius nokuda inonyanya mhando diode - nesilicon) uye kufadza muviri tembiricha (zvakasiyana-siyana parameters, zvichienderana nesimba kugadzwa uye mugadziri).
