02 Cov txiaj ntsig ntawm YMIN Capacitors hauv Inverters
- Kev Muaj Peev Xwm Ceev Siab
Ntawm sab nkag ntawm cov micro-inverters, cov khoom siv hluav taws xob rov ua dua tshiab xws li cov vaj huam sib luag hnub ci thiab cov cua tshuab tsim hluav taws xob uas xav tau hloov los ntawm lub inverter hauv lub sijhawm luv luv. Thaum lub sijhawm no, cov khoom siv tam sim no tuaj yeem nce ntxiv sai heev.YMINCov capacitors, nrog lawv cov capacitance density siab, tuaj yeem khaws cia ntau dua hauv tib lub ntim, nqus ib feem ntawm lub zog, thiab pab lub inverter hauv kev ua kom lub zog du thiab ruaj khov tam sim no. Qhov no ua rau kev hloov pauv zoo dua, ua rau DC-rau-AC hloov pauv thiab xyuas kom meej tias kev xa hluav taws xob mus rau lub grid lossis lwm qhov chaw xav tau zoo. - Kev Tiv Thaiv Tam Sim No Siab Ripple
Thaum cov inverters ua haujlwm yam tsis muaj kev kho qhov fais fab, lawv cov zis tam sim no yuav muaj cov khoom sib xws tseem ceeb. Cov capacitors lim dej tso zis tau zoo txo cov ntsiab lus harmonic, ua tau raws li qhov xav tau ntawm lub nra hnyav rau lub zog AC zoo thiab ua kom ua raws li cov qauv kev sib txuas ntawm lub grid. Qhov no txo qhov cuam tshuam tsis zoo rau lub grid. Tsis tas li ntawd, ntawm sab DC input, cov capacitors lim dej ntxiv tshem tawm suab nrov thiab cuam tshuam hauv DC lub zog, ua kom ntseeg tau tias DC input huv dua thiab txo qhov cuam tshuam ntawm cov teeb liab cuam tshuam rau cov voj voog inverter tom ntej. - Kev Tiv Thaiv Hluav Taws Xob Siab
Vim muaj kev hloov pauv ntawm lub hnub ci, qhov hluav taws xob tso tawm los ntawm cov tshuab photovoltaic tuaj yeem tsis ruaj khov. Ntxiv mus, thaum lub sijhawm hloov pauv, cov khoom siv hluav taws xob semiconductor hauv inverters tsim cov hluav taws xob thiab tam sim no nce siab. Cov buffer capacitors tuaj yeem nqus cov hluav taws xob no, tiv thaiv cov khoom siv hluav taws xob thiab ua kom cov hluav taws xob thiab tam sim no hloov pauv du. Qhov no txo qhov poob zog thaum lub sijhawm hloov pauv, txhim kho kev ua haujlwm ntawm inverter, thiab tiv thaiv cov khoom siv hluav taws xob kom tsis txhob raug puas tsuaj los ntawm cov hluav taws xob ntau dhau lossis cov hluav taws xob nce siab.
