Frequently Asked Questions

What voltage ratings are available for power capacitors?

Faratronic power capacitors are available from 600V DC to 3000V DC. Common ratings include 700V, 900V, 1100V, 1300V, and 2000V for various industrial and renewable energy applications. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

Select voltage rating at least 1.5x the nominal operating voltage to account for transients and ensure long lifetime.

What applications are power capacitors used for?

Power capacitors are used in industrial motor drives, solar inverters, wind turbine converters, UPS systems, power factor correction equipment, and high-power welding equipment. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

For high-power applications (>10kW), select power capacitors with appropriate voltage and ripple current ratings for your specific application.

How do I calculate ripple current for power capacitor selection?

Ripple current depends on load current, switching frequency, and DC bus voltage. For three-phase inverters: I_ripple ≈ 0.61 × I_DC. Always include margin for harmonic content. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

Contact our FAE team with your inverter specifications for detailed ripple current calculations and capacitor sizing.

What is the difference between power capacitors and standard film capacitors?

Power capacitors feature larger case sizes, higher voltage ratings, higher ripple current capability, and enhanced thermal management. They are designed for continuous high-power operation. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

For applications above 10kW or with high ripple current, select power capacitors rather than standard film capacitors.

Can power capacitors be used in series for higher voltage?

Yes, power capacitors can be connected in series with voltage balancing resistors. This is common for high-voltage applications above 1500V DC. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

For series connection, use matched capacitors and implement proper voltage balancing. Contact our FAE team for series connection design support.

What cooling is required for power capacitors?

Power capacitors may require forced air cooling or liquid cooling depending on power dissipation. Natural convection is sufficient for lower power applications. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

Calculate power dissipation (P = I² × ESR) and ensure adequate cooling. Contact our FAE team for thermal design assistance.
