Title:
ALUMINUM ELECTROLYTIC CAPACITOR INTEGRATED MODULE
Document Type and Number:
WIPO Patent Application WO/2022/151899
Kind Code:
A1
Abstract:
An aluminum electrolytic capacitor integrated module. A modular aluminum electrolytic capacitor integrated with discrete aluminum electrolytic capacitor units conducts heat outwards in a centralized and insulated manner by means of an insulating heat-conducting gasket, and therefore, a heat dissipator can be used for efficient cooling. Seals of the discrete aluminum electrolytic capacitor are sealed twice, such that the service life of the modular capacitor breaks through the service life upper limit of 15 years of a traditional discrete aluminum electrolytic capacitor. A temperature sensor is additionally mounted, such that a user monitors, in real time, the internal temperature rise and the service life of the modular capacitor. A Y capacitor module is additionally mounted, such that the problem of reverse pulse current formation performed by a capacitor electrolyte on negative electrode foil caused by high-order harmonics on a power direct-current bus is solved. Moreover, common-mode interference is effectively suppressed, thereby improving the EMC reliability of the machine system; and the modular aluminum electrolytic capacitor integrated with the above technology is applied to a power electronic apparatus, and has technical advantages in many aspects such as heat dissipation, low temperature rise, long service life and EMI noise suppression.
