Application of DC-link DC filter capacitor

In the past years of development, the use of metal film and metal film on the segmentation of DC filter has been considerable development, now the film manufacturers to develop more thin film, and improve the segmentation technology of metallization greatly helped the development of the capacitor, the voltage range of polypropylene film capacitor can cover 600VDC to 2200VDC is more economical than electrolytic capacitor. Film capacitors have many advantages, so that it can replace the electrolytic capacitor industry and power electronic power conversion market trends.

These advantages include:
Ability to withstand high effective current
Can withstand two times the rated voltage of the overvoltage
Can withstand the reverse voltage
Ability to withstand the peak current
Long life, can be stored for a long time
However, only an alternative is not a micro method of micro method, instead, instead of functional.
Of course, although the film capacitor technology has made considerable progress, but not all applications can replace the field of electrolysis
