If the application's power supply breaks down, this is not a pleasant situation. Würth Elektronik eiSos built up a demonstration showing a hot-swappable backup solution with a size of 10 cm x 18.5 cm (3.94 inch x 7.3 inches). The input voltage is 24V, and the backup output voltage is 12 V for a normal industrial power rail application. The available output power is 30 W (12 V @ 2.5 A). We also talk about the classification of Supercapacitors, the model parameters and performance, and the charge-, discharge, and frequency behavior.

The double-stage filter family is therefore also appropriate for applications with particularly high EMC emissions, as is frequently encountered in industry. Typical applications include machines and systems for automatic production, motor drives and industrial plant machinery. These powerful filters are also the first choice for modern frequency inverters for motor control.

These electrolytic capacitors have high instability and poor tolerances, and their performance deteriorates when they are subjected to high leakage current or high temperatures. Plastic film and paper capacitors are usually used in circuits that demand capacitors with good aging performance, high stability, and high current-carrying capability. For high-frequency applications, ceramic capacitors are a good option. However, these capacitors have poor aging performance.
