Film capacitors play an important role in every aspect of UPS.

Use of Film Capacitor in UPS and Switching Power Supply

Film capacitor has many excellent characteristics, so it is a kind of capacitor with superior performance. Its main characteristics are as follows: high insulation resistance, excellent frequency characteristics (wide frequency response), and low dielectric loss.

Film capacitors are mainly used in electronics, home appliances, communications, electric power, electrified railways, hybrid vehicles, wind power, solar power and other industries. The stable development of these industries has promoted the growth of the film capacitor market. This article will tell you the role of film capacitors in the field of UPS and switching power supplies. Hopefully the content of this article can help you better understand film capacitors.

The uninterruptible power supply (UPS) is used to provide stable power to its load, thereby isolating the load from the power supply line, and avoiding the load from being affected by the interruption of the power supply line (including spikes, overvoltage, undervoltage and power outages). When the UPS is out of power, depending on the size of the battery, it can supply power to the load for several minutes to several hours. Uninterruptible power supply can also be understood as such a device: it specifically protects the load so that it will not be affected by unstable power lines. This is a way to ensure the reliability of its working life.
