In new energy, what are the advantages of film capacitors compared to aluminum electrolytic capacitors?

 

1. Aluminum electrolytic capacitors are liquid capacitors with short service life. Many users of solar and wind energy products require more than 15 years of product life, that is, the products must be reliable within 15 years, because the maintenance costs of wind energy products are very expensive and difficult. The electrolytic liquid materials of aluminum electrolytic capacitors are volatile, and generally cannot reach the service life of 15 years and need to be replaced two to three times; film capacitors are solid capacitors that can reach the service life of 15 years.

 

2. The ESR value of the dielectric material of the film capacitor is low, so its calorific value is very low; in addition, it can achieve high ripple voltage.

 

3. Film capacitors have the characteristics of a wider operating environment temperature range, and their stability at low temperatures is very good.

 

4. The filtering ability of film capacitors is many times stronger than that of aluminum capacitors. If the filtering is better, film capacitors can be used, and the conversion efficiency is higher. The same is true for the development trend of wind energy and solar energy applications.
