An uninterruptible power supply (UPS) is used to provide a stable power supply to its load, thereby isolating the load from the power line and preventing the load from being affected by power line interruptions (including spikes, overvoltage and undervoltage, and power outages). When a UPS fails , it can power the load for several minutes to several hours depending on the size of the battery. An uninterruptible power supply can also be understood as a device that specifically protects the load from being affected by unstable power lines. This is the best way to ensure reliability during its working life. According to different topologies , UPS is mainly divided into three types: backup, interactive and online.


Film capacitors play a vital role in every aspect of UPS. Please refer to the following application example
