Four advantages of using film capacitors in new energy

In the development of new energy, film capacitors have always been the focus of attention, so where is the advantage of film capacitors and aluminum electrolytic capacitors in new energy sources, let's take a look at editing together. I hope the content of this article can help everyone!

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. The second advantage is that 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. Feature 3, there is a wider use of the ambient temperature range, which is also the difference between liquid capacitors and solid capacitors. Film capacitors have very good stability at low temperatures.

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 development of wind energy and solar energy applications.
