Four advantages of using film capacitors in new energy

Film capacitor has always been the focus of attention in the development of new energy, so what is the advantage of film capacitance compared with aluminium electrolytic capacitor in new energy?

1. Aluminum electrolytic capacitors are liquid capacitors. First of all, there is a service life. Now many users of solar energy and wind energy products need to have a product life expectancy of more than 15 years. The product must be reliable within 15 years because wind energy Product maintenance costs are very expensive and difficult. The film capacitor is a solid capacitor, which can meet the requirements of this use. The aluminum electrolytic capacitor has the volatilization of the electrolyte material. Generally, it has no way to reach the service life of 15 years. If it is to achieve the experimental life of 15 years, it means that the period must be Replace two or three times.

2. Due to the characteristics of the dielectric material of the film capacitor, it has a low ESR value, so its heat generation is very low, and it can also achieve a high resistance to ripple voltage.

3. It has the characteristics of wider use of the ambient temperature range, which is also the difference between the liquid capacitor and the solid capacitor. The stability of the film capacitor in the low temperature state is very good.

4. The film capacitor filter capability is many times stronger than aluminum capacitors. If the filtering is good, a film capacitor can be used, and the conversion efficiency is higher. This is the trend of the development of wind energy and solar energy applications.
