Ibikoresho byo kubika ingufu
Uburyo bwo kubika ingufu ni igice cy'ingenzi cya sisitemu zigezweho z'ingufu zishobora kongera gukoreshwa. Zikoreshwa cyane kuko zigabanya neza imyanda ikoreshwa mu ngufu kandi zikongera imikorere myiza ya sisitemu z'ingufu. Bitewe n'imikoranire hagati ya bateri n'umuyoboro w'amashanyarazi, abahindura ingufu basabwa gukora ihinduranya rya AC-DC no gutuma ingufu zinyura mu cyerekezo cy'imirongo ibiri. Byongeye kandi, abahindura ingufu bagira uruhare runini mu buryo bwo kubika ingufu binyuze mu kugenzura ingano n'icyerekezo cy'umuyoboro w'amazi, bigatuma gukata imisozi miremire no kuzuza ikibaya kugira ngo byongere imikorere myiza y'ingufu, ndetse no gutanga uburinzi bw'umutwaro kugira ngo sisitemu ikomeze kuba nziza.
Hagati y'uruziga rw'imashini ikosora ibintu n'uruziga rw'imashini ihindura ibintu, hariCapacitor ya DC-LINKirakenewe kugira ngo ishyigikire umuyoboro w'amashanyarazi n'iyungurura. Inshingano yayo y'ibanze ni ukwinjiza umuyoboro mwinshi w'amashanyarazi kuri bisi ya DC-LINK, bikarinda ko umuyoboro mwinshi w'amashanyarazi ukorwa ku muyoboro wa DC-LINK. Ibi kandi birinda impera y'umuzigo ingaruka z'umuyoboro urenze urugero w'amashanyarazi.
Capacitors za YMIN zifite ibi bikurikira mu gice cy'ihinduranya ry'amakuru
01. Ubushobozi bwo hejuru
Capacitor ya DC-Link ibika ingufu z'amashanyarazi, bigatuma itanga ingufu zihoraho kuri sisitemu y'amashanyarazi mu gihe cy'ihindagurika rikomeye ry'amashanyarazi cyangwa ibura ry'amashanyarazi, bigatuma sisitemu ikora neza. Byongeye kandi, iyo sisitemu y'amashanyarazi ikeneye ingufu nyinshi, capacitor ya DC-Link ishobora kurekura ingufu zibitswe vuba kugira ngo ihuze n'ibikenewe by'igihe gito. Mu mitwaro ikoreshwa nka moteri, capacitor itanga kandi uburyo bwo kwishyura ingufu zikoreshwa, igatuza ingufu, kandi ikanoza imikorere ya moteri. Ibi bigira uruhare runini mu kongera imikorere myiza n'ituze bya sisitemu.
02. Ubudahangarwa bw'amashanyarazi menshi cyane
Capacitors za YMIN, zifite ubushobozi bwo kurwanya amashanyarazi menshi cyane, zishobora no kuba ibikoresho birinda. Mu gihe cyo gukoresha converter, zirinda ibice by'ikoranabuhanga byangiritse bitewe n'izamuka ry'amashanyarazi. Ibi bituma converter zo kubika ingufu zitanga amashanyarazi ahamye n'ubufasha ku muyoboro w'amashanyarazi, bigatuma sisitemu ikora neza.
03. Ubudahangarwa bw'Umuvuduko Ukabije w'Umuriro
Capacitors za YMIN zifata neza imiyoboro miremire ikorwa na converter ku mpera ya DC-Link, bigatuma habaho kugenzura neza ingufu zisohoka binyuze mu kugenzura umuyoboro w'amashanyarazi. Ibi bituma converter yuzuza ibisabwa n'ibintu bitandukanye kandi igatanga umusaruro mwiza wa AC. Mu gihe cy'uburyo bwo gutangira bwa converters, capacitors za YMIN zigize igice cy'uruziga rwo gusharija, bigafasha gukumira ingaruka nyinshi ku ngufu zinjiye n'umutwaro.
04. Ubuzima Burambye
Capacitors za YMIN, zikorwa binyuze mu buryo busanzwe kandi zigakorerwa isuzuma rikomeye mbere yo gutanga, zifite ubucucike bwinshi n'ubudahangarwa bwiza bw'umuvuduko w'amashanyarazi. Izi ngamba zituma abahindura ingufu mu buryo bwo kubika ingufu bakora neza mu gihe kirekire, bigabanya ikiguzi cyo kunanirwa no kubungabunga.

Shyira mu ncamake
YMINCapacitors zigira uruhare runini mu kubika ingufu bitewe n'ubushobozi bwazo bwinshi, kwihanganira voltage nyinshi cyane, no kuramba igihe kirekire. Zifasha inverters zo kubika ingufu kurangiza guhindura ingufu mu cyerekezo cy'impande zombi, kugenzura ingufu n'indi mirimo, no kunoza ikwirakwizwa ry'umuyoboro w'amashanyarazi binyuze mu kogosha no kuzuza ikibaya. Zinoza ikoreshwa ry'ingufu rya inverter mu kubika ingufu kandi ni zo mahitamo meza ku inverters zo mu rwego rwa capacitor.
