If the power supply of the application breaks down, this is not a pleasant situation. Würth Elektronik eiSos built up a demonstration, which shows a hot swappable backup. 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, performance and the charge-, discharge and frequency behavior. For the power stage, we used the software for and from the LTC3351 from Analog Devices.
This presentation was part of our virtual conference (26-29 Apr): WE meet @ Digital Days 2021
