Dry capacitors and Oil capacitors
Most of the customers who buy power capacitors in the industry now choose dry capacitors. The reason for such a situation is inseparable from the advantages of dry capacitors themselves. Compared with oil capacitors, they have many advantages in terms of product performance, environmental protect...Read more -
Introduction to one of the raw material in film capacitors – base film（polypropylene film）
With the continuous expansion of new energy demand, it is expected that China’s film capacitor market will enter a high growth period again in the next few years. Polypropylene film, the core material of film capacitors, is continuing to expand its supply and demand gap due to the rapid expansion...Read more -
Introduction to the difference between active and reactive power in AC circuits
In an AC circuit, there are two types of electrical power supplied to the load from the power supply: one is active power and the other is reactive power. When the load is resistive load, the power consumed is active power, when the load is capacitive or inductive load, the consumption is reactiv...Read more -
Analysis of film capacitors instead of electrolytic capacitors in DC-Link capacitors（2）
This week we continue with last week’s article. 1.2 Electrolytic capacitors The dielectric used in electrolytic capacitors is aluminum oxide formed by corrosion of aluminum, with a dielectric constant of 8 to 8.5 and a working dielectric strength of about 0.07V/A (1µm=10000A). However, it...Read more -
Analysis of film capacitors instead of electrolytic capacitors in DC-Link capacitors（1）
This week we’re going to analyze the use of film capacitors instead of electrolytic capacitors in DC-link capacitors. This article will be divided into two parts. With the development of new energy industry, variable current technology is commonly used accordingly, and DC-Link capacitors a...Read more -
