  • Capacitor Classification
    According to whether the capacitance can be adjusted, it can be divided into fixed capacitor, variable capacitor and trimmer capacitor. According to the purpose, it can be divided into coupling capacitors, bypass capacitors, tuning capacitors, filter capacitors, and high-voltage capacitors
  • Selecting and Applying Aluminum Electrolytic Capacitors for Inverter Applications
    Aluminum electrolytic capacitors are widely used in all types of inverter power systems, from variable-speed drives to welders to UPS units. This paper discusses the considerations involved in selecting the right type of aluminum electrolytic bus capacitors for such power systems. The relationship
  • Selecting and Applying DC Link Bus Capacitors for Inverter Applications
    Abstract, aluminum electrolytic and DC film capacitors are widely used in all types of inverter power systems, from variable-speed drives to welders, UPS systems and inverters for renewable energy. This paper discusses the considerations involved in selecting the right type of bus capacitors
  • Predicting Operating Temperature and Expected Lifetime of Aluminum-Electrolytic Bus Capacitors with Thermal Modeling
    Large-can aluminum electrolytic capacitors are widely used as bus capacitors in variable-speed drives, UPS systems and inverter power systems. Accurate thermal modeling of the capacitor's internal temperature is needed to predict life, and this is a challenge because of the anisotropic nature
  • Capacitance Set Point Stability During Random Vibration Test
    The variable end of a CSV4-900-01 vacuum capacitor was bolted to a thick phenolic disc. This disc was clamped into a rigid test fixture, which was bolted securely to the working table of the vibration test rig (Figure 1). The fixed end of the vacuum capacitor was left free to
