Application Analysis of film capacitors repositoque electrolytic capacitors in DC-Link Capacitors

Cum celeri progressionem novum industria industria, potestas conversionem technology late applicantur in agros ut ventus potestate, photovoltaic potentia generationem et novum industria vehicles. Ut a key component in his systems, in perficientur DC-Link Capacitors directe impingit reliability et Lifespan totius ratio. Traditionally, electrolytic capacitors sunt late usus debitum ad eorum inferioris sumptus, sed eorum limitations in altus-voltage, summus current, et longa-lifespan missionibus facti magis apparent. In Contra, film capacitors, cum suis superior perficientur, sunt emergentes ut idealis alternative.

ERECTIO

Film capacitors utilitas metallized depositione technology, ubi metallum iacuit est vaporized onto a film Dielectric ad consequi sui, sanitatem proprietatibus, IsOlting defectus et enhancing reliablity. Illi exhibent excelsum dielectric fortitudinem (usque 250v / μm pro DC filtering) potest sustinere voltage superbit usque ad bis rated valorem, et pluma et elementum (more eas apta alta / DT Applications. Praeterea, film capacitors sunt non-polarized, tolerant de inversa voltage, et offer a lifespan excedentia XV annis sine crebris replacements.

Electrolytic capacitors inniti Aluminium Oxide Dielectrics et Liquid electrolytes. In dielectric fortitudo est relative humilis (de 0.07v / Å), cum a maximum opus voltage typice limited ad 450v. Superiore voltages eget series hospites, cum additional resistores et Diodes ad statera voltage et ne avertere naufragii. ESR in altiorem limites Ripple Current Handling (circa 20MA / μf), et volatile electrolyte breviate eorum lifespan, necessitating iusto sustentationem in novus industria applications.

Applicationem commoda

In nova industria vehicles, exempli gratia, DC-Link Capacitors oportet tractamus 330vdc opus voltage et 150arms Ripple current. Film capacitors occursum his requisitis labore, cum electrolytic capacitors requirere multa parallela turmas, augendae ratio complexionem et magnitudine. In overvoltage missionibus (E.G., blasphemant transit), film capacitorors potest pati instantanea overvoltages 2un, cum electrolytic capacitoribus tolerare tantum 1.2un, requiring seriei unitates et reducendo fidem.

Conclusio

Cum progressionum in metallization technology et sumptus reductiones, film capacitors demonstrabo significant commoda in altus-intentione, princeps laniatus current, et longa-lifespan applications. In pacto consilia (E.G., integrated busbars) adhuc redigendum errant inductance et amplio ratio efficientiam. Ut, in novo industria sector, repositoque electrolytic capacitors cum film capacitors facta est in irreversible trend.
