Nyika yemagetsi inotsamira pane akasiyana siyana mavara, mumwe nemumwe achiita basa rakakosha. Pakati peizvi, diode dzinomira pachena pakukwanisa kwavo kudzora kuyerera kwemagetsi. Nhasi, isu tinotarisa mune chaiyo mhando - iyo Schottky diode, yakasarudzika musanganiswa wesimbi uye semiconductor ine huwandu hwekushandisa kwakakosha.
Kunzwisisa Schottky Diode
Kusiyana neakajairika pn junction diode, iyo Schottky diode inoumba mubatanidzwa pakati pesimbi uye semiconductor. Izvi zvinogadzira Schottky barriers, nzvimbo iyo maerekitironi kuyerera kunorambidzwa. Kana magetsi akaiswa pamberi (positive padivi resimbi), maerekitironi anokunda chipingamupinyi uye ikozvino inoyerera nyore. Nekudaro, kushandisa reverse voltage kunogadzira chipingamupinyi chakasimba, chinotadzisa kuyerera kwazvino.
Chiratidzo uye Hunhu
Chiratidzo cheSchottky diode chakafanana nedhiodhi yenguva dzose ine mutsara wakachinjika unocheka gonyotatu inonongedza kune yakanaka terminal. Yayo VI hunhu curve yakafanana nepn junction diode, asi ine musiyano wakakosha: kuderera zvakanyanya kumberi kwevolti kudonha, kazhinji pakati pe0.2 kusvika 0.3 volts. Izvi zvinoshandura kuderedza kurasikirwa kwesimba panguva yekushanda.
Nheyo Yekushanda
Musimboti wemusimboti wekushanda kweSchottky diode uri mukusiyana-siyana kwesimba remaerekitironi muzvinhu zvakasiyana. Kana simbi nen-mhando semiconductor zvikasangana, maerekitironi anoyerera achiyambuka makutano kumativi ose. Kuisa mhepo yekumberi kunosimbisa kuyerera kwakananga kune semiconductor, ichigonesa ikozvino.
Zvishandiso zveSchottky Diode
Schottky diodes vanozviwana vari mune akasiyana emagetsi maapplication nekuda kweakasarudzika zvivakwa:
RF Mixers uye Detector: yavo yakasarudzika yekuchinja kumhanya uye yakakwirira-frequency kugona inoita kuti ive yakanakira redhiyo frequency (RF) application senge diode ring mixers.
Power Rectifiers: Kugona kubata makwikwi akakwira uye mavoltages ane yakaderera kumberi voltage inodonha inoita kuti ishande simba rectifier, ichideredza kurasikirwa kwemagetsi zvichienzaniswa nepn junction diode.
Simba KANA Masekete: Mumaseketi umo magetsi maviri anotyaira mutoro (senge bhatiri backups), Schottky diode inodzivirira ikozvino kuti irege kuyerera ichidzokera kune imwe inopihwa kubva kune imwe.
Solar Cell Applications: Solar panels inowanzobatanidzwa kune mabhatiri anochajiswa, kazhinji lead-asidhi. Kudzivirira ikozvino kuti irege kuyerera ichidzokera mumaseru ezuva usiku, Schottky diodes inoshandiswa mukusagadzirisa.
Zvakanakira uye Zvakaipa
Schottky diodes inopa akawanda mabhenefiti:
Low Capacitance: Iyo inoregeredza yekuderera inokonzeresa yakaderera capacitance, ichiita kuti ive yakakodzera kune yakakwira-frequency application.
Kukurumidza Kuchinja: Iko kukurumidza kushandura kubva kumberi kuenda kune kure kunobvumira kukurumidza-kumhanya kushanda.
High Current Density: Nzvimbo diki yekuderera inovagonesa kubata yakakwira density iripo.
Low Turn-On Voltage: Iyo yekumberi voltage inodonha ye0.2 kusvika 0.3 volts yakaderera zvakanyanya pane pn junction diode.
Nekudaro, pane imwe kiyi drawback:
Yakakwira Reverse Leakage Yazvino: Schottky diodes inoratidza yakakwira reverse leakage ikozvino ichienzaniswa nepn junction diodes. Izvi zvinogona kuve kunetseka mune mamwe maapplication.
Mhedziso
Iyo Schottky diode, ine yakasarudzika simbi-semiconductor junction, inopa yakakosha musanganiswa weyakaderera mberi voltage kudonha, kukurumidza kushandura kumhanya, uye yakakwirira ikozvino kubata kugona. Izvi zvinoita kuti zvive zvisingadzokerike zvikamu mumaseketi akasiyana emagetsi, kubva kune magetsi kusvika kune solar energy system. Sezvo tekinoroji ichiramba ichishanduka, iyo Schottky diode ine chokwadi chekuramba yakavimbika workhorse muindasitiri yemagetsi.
