[Sarudzo Yekutungamira] Maitiro ekuyeresa Yakakwira Voltage uye Hupenyu Hurefu muMiniaturized OBCs? Kuongororwa kweYMIN LKD High-Voltage Capacitors

Nhanganyaya

Mu800V OBC uye DC-DC magadzirirwo, kusarudzwa kwecapacitor kwave chinhu chakakosha chinokanganisa kuwanda kwesimba, kugona, uye kuvimbika. Traditional aluminum electrolytic capacitors, nekuda kwehukuru hwayo, hupenyu hupfupi, uye hurombo hwepamusoro-frequency maitiro, haigone kuita izvi zvinodiwa. Ichi chinyorwa chichaongorora mabhenefiti ekuita kweYMIN Electronics 'LKD akateedzana akakwira-voltage aluminium electrolytic capacitors maererano neminiaturization, yakakwirira ripple ikozvino kuramba, uye hupenyu hurefu, ichipa mainjiniya gwaro rekusarudza.

OBC - YMIN Aluminium Electrolytic Capacitor LKD Solution

Nekuwanda kwemidziyo yeSiC uye kuwedzera ma frequency ekuchinja, ma capacitor muOBC modules anofanirwa kumirisana nepamusoro ripple currents uye thermal stress. Conventional aluminum electrolytic capacitors anowanzo kuwedzeredza uye ane hupenyu hupfupi. Kuwana high capacitance, high voltage resistance, low ESR, uye hupenyu hurefu muhukuru hukuru hwave huripo hwekurwadziwa muOBC design.

- Root Cause Technical Analysis -

Mhedzisiro yedambudziko iri mune izvo uye maitiro zvinogumira zvechinyakare capacitors:

Ma electrolyte akajairika anoshanduka nyore nyore pakupisa kwakanyanya, zvichiita kuti capacitance ipere uye kuwedzera ESR;

Zvakajairwa zvimiro zvekugadzira zvine yakaderera capacitance density, zvichiita kuti zviome kuyera yakakwira voltage uye capacitance;

Kusavimbika kwekuisa chisimbiso kwakaringana kunotungamira mukudonha munzvimbo dzevibration.

Makiyi ma paramita akadai se capacitance density, ESR @ 100kHz, yakayerwa ripple current @ 105°C, uye lifespan yakanangana nebudiriro system.

- YMIN Solutions uye Maitiro Mabhenefiti -

Iyo YMIN LKD yakatevedzana inoshandisa akati wandei maitiro matsva:

1. High-density electrode foil: Inowedzera capacitance per unit volume, kuderedza ivhu ne20% kusvika 40% kana ichienzaniswa nemishonga yakafanana;

2. Low-impedance electrolyte: Zvinobudirira inoderedza ESR uye inovandudza high-frequency ripple tolerance;

3. Yakasimbiswa kuiswa chisimbiso uye kuputika-uchapupu chimiro: Inopfuura 10G vibration resistance test, kubvisa njodzi dzekudonha;

4. High-voltage redundancy design: Inopa yakawanda voltage margin, yakakodzera kushandiswa pamapuratifomu e800V uye pamusoro.

Kuvimbika Data Verification & Sarudzo Mazano

Sezvinoonekwa, iyo LKD yakatevedzana inokunda zvakajairwa zvigadzirwa maererano nehukuru, ESR, ripple kuramba, uye hupenyu.

- Mamiriro ekushandisa uye akakurudzirwa Models - Iyo LKD nhevedzano yakanakira: OBC PFC inowedzera wedunhu kuburitsa kusefa; DC-Link rutsigiro uye buffering; uye DC-DC kusefa.

- Inokurudzirwa Mienzaniso -

LKD 700V 150μF 25×50: Inokodzera 1200V DC-Link systems;

LKD 500V 330μF 25 × 50: Inokodzera kusefa kwepamusoro-soro mu800V systems;

LKD 450V 330μF: Kuenzanisa ukuru uye simba rinodiwa;

LKD 500V 220μF: Inokodzera kushandiswa munzvimbo yakanyanya-inomanikidzwa maapplication.

Mhedziso

YMIN's LKD nhevedzano, kuburikidza nezvinhu zvitsva uye zvimiro, zvinobudirira kugadzirisa kuvimbika uye compact saizi zvinodiwa zvecapacitor mune yakakwira-voltage, yakakwirira-frequency, uye yakakwirira-tembiricha maapplication. Yakave iyo capacitor yesarudzo yeOBC mapurojekiti kumakambani mazhinji anotungamira emotokari. Isu tinotsigira mashandisirwo emuenzaniso uye rutsigiro rwehunyanzvi, kubatsira mainjiniya nekukurumidza kuita mapurojekiti.
