AC Filter Metalized Film Capacitor

AC Filter Metallized Film Capacitor

What are AC Filter Metalized Film Capacitor?

• Purpose: Primarily used to filter out unwanted harmonics (distorted frequencies) in AC power systems.  
• Construction:
  • Dielectric: Made with thin layers of metallized polypropylene film. 
  • Metallization: A thin layer of metal (usually aluminum) is deposited onto the film, creating a conductive layer.  
  • Self-Healing: If a localized short circuit occurs, the metallization around the fault evaporates, isolating the area and allowing the capacitor to continue functioning.

Key Features AC Filter Metalized Film Capacitor:

• High Capacitance Density: Can achieve high capacitance values in a compact size. 
• Low Loss: Minimal energy dissipation during operation.   
• Self-Healing: Increases reliability and extends service life.   
• High Peak Current Capability: Can withstand high current surges.  
• Wide Range of Applications: Suitable for various applications, including:
  • Inverter Systems: Smoothing output waveforms and improving efficiency.
  • Motor Drives: Reducing harmonics generated by variable speed drives.
  • Battery Chargers: Filtering ripple currents.  
  • Power Factor Correction (PFC): Improving power quality.  

Applications AC Filter Metalized Film Capacitor:

• Industrial: Power factor correction, harmonic filtering in industrial equipment.
