Nekukura zvishoma nezvishoma kwetekinoroji ye gallium nitride (GaN), nhamba iri kuwedzera yevashanduri veAC/DC vari kushandisa GaN sezvinhu zvinochinja kuti zvitsive zvikamu zvechinyakare zvesilicon. Mukushandiswa kwetekinoroji iyi itsva, ma capacitor anofambisa magetsi anoitawo basa rakakosha.
YMIN yagara yakazvipira kugadzira ma capacitor ekufambisa magetsi (conductors) ekushandisa muGaN-based AC/DC converters uye yakabudirira mumabasa akasiyana-siyana, akadai sekuchaja nekukurumidza (kubva kare IQ fast charging, PD2.0, PD3.0, PD3.1), ma adapter emalaptop, electric bike fast charging, onboard chargers (OBC)/DC fast charging piles, server power supplies, nezvimwewo. Aya ma capacitor matsva ekufambisa magetsi anogona kuzadzisa zvizere hunhu hwakanaka hweGaN, achiita zvakanaka muzviitiko zvekushandisa uye achisangana nezvinodiwa nevatengi zvekuvandudza mashandiro uye kuvandudza mashandiro. Pazasi, tichatsanangura hunhu hwavo hwekushandisa.
01 GaN inobatsira kuderedza ma converter eAC/DC
Maseketi mazhinji anoshandisa DC voltage pachinzvimbo cheAC voltage, uye maAC/DC converters akakosha semidziyo inoshandura simba reAC rekutengesa rinopihwa kudzimba nemabhizinesi kuita DC power. Kana simba racho rakafanana, tsika ndeyekuita kuti maconverters asanyanya kushandiswa kubva pakuona kwekuchengetedza nzvimbo uye kutakurwa.
Kushandiswa kweGaN (gallium nitride) kwafambira mberi zvikuru mukuita kuti maAC/DC converters ave mashoma. Zvichienzaniswa nezvikamu zveSi (silicon) zvechinyakare, zvakanakira zveGaN kurasikirwa kudiki kwekuchinja, kushanda zvakanaka, kumhanya kwakanyanya kwekufambisa maerekitironi uye hunhu hwekufambisa. Izvi zvinobvumira AC/DC converter kudzora mashandiro ekuchinja, zvichikonzera kushandurwa kwesimba zviri nani.
Pamusoro pezvo, ma "high switching frequency" anogona kusarudzwa, zvichibvumira kushandiswa kwezvikamu zvidiki zvisingashande. Izvi zvinodaro nekuti GaN inogona kuchengetedza kushanda zvakanaka kunyangwe pa "high-frequency switching", zvakafanana ne "low-frequency switching" yeSi.
02 Basa rakakosha rema capacitor ekufambisa
Mukugadzirwa kwemaAC/DC converters, ma output capacitors akakosha. Ma conductive capacitors anogona kubatsira kuderedza ripple ye output voltage uye anoita basa rakakosha mukusefa muma high-power switching circuits. Kana capacitor ikatora ripple current, inozopedzisira yagadzira ripple voltage. Mukushanda, zvinowanzo dikanwa kuti power supply ripple isapfuure 1% ye operating voltage yemuchina.
Kana GaN ikashandiswa, ESR yeYMIN solid-liquid hybrid capacitors inogara yakasimba muhukuru hwe10KHz ~ 800KHz, iyo inogona kusangana nezvinodiwa zveGAN high-frequency switching.
Saka, muma AC/DC converters anoshandisa gallium nitride, ma conductive capacitors ndiwo akanakisa pakuburitsa magetsi.
03 YMIN yakabatana ne capacitor inoenderana ne conductivity
Nekushandiswa kweGaN, kushandiswa kwema "high-frequency switching AC/DC converters" kwakawedzera zvishoma nezvishoma. Kuti irambe ichizadzisa zvinodiwa nevatengi, YMIN, semugadziri wemusika wema "conductive capacitors", inoshandisa tekinoroji yayo yemazuva ano inoshanda zvakanyanya/yakavimbika kuti iunze vatengi mhando itsva, yakazara yezvigadzirwa (kusvika ku100V) uye mabasa emhando yepamusoro.

Zvigadzirwa zvedu zve polymer solid aluminum electrolytic capacitors, polymer solid-liquid hybrid aluminum electrolytic capacitors, multilayer polymer solid aluminum electrolytic, uye polymer tantalum capacitor series zvinogona kuenzaniswa zvinobudirira nema AC/DC converters matsva.
Ma capacitor aya ekufambisa magetsi anoshandiswa zvakanyanya mumagetsi e5-20V anoshandiswa zvakanyanya mumidziyo yehurumende, magetsi e24V ekushandisa muindasitiri, uye magetsi e48V ekushandisa mumidziyo yekutaurirana. Kuti tikwanise kugadzirisa dambudziko rekushomeka kwemagetsi mumakore achangopfuura, kushanda nesimba kwakawanda kunodiwa, uye huwandu hwezvigadzirwa zvinoshanduka kuenda ku48V huri kuwedzera (mota, nzvimbo dzedata, USB-PD, nezvimwewo), zvichiwedzera kuwedzera kwekushandiswa kweGaN nema capacitor ekufambisa magetsi.
04 Mhedziso
Munguva itsva, YMIN inotevedzera pfungwa yebasa rekuti "Capacitor Solutions, Bvunza YMIN nezvemashandisirwo ako", yakatsunga kuzadzisa zvinodiwa zvitsva uye budiriro itsva kuburikidza nemashandisirwo matsva nemhinduro itsva, uye inoongorora nekushingaira mikana yekudzikisa AC/DC converters pasi pemashandisirwo eGaN. YMIN inosimbirira pakutarisa pakugadzirwa kwezvigadzirwa zvitsva, kugadzira nemazvo uye kusimudzira mashandisirwo, kupa vatengi ma capacitor emhando yepamusoro, kupa masevhisi matsva uye emhando yepamusoro, kuwedzera mari yekutsvaga, uye kukurudzira kufambira mberi kweindasitiri.
