The Würth Elektronik webinar titled “WE Backup Your Application – a real-life Supercapacitor backup solution” provides a comprehensive overview of supercapacitor technologies and their applications in power backup systems. Presented by Markus Eberle and Frank Hahne, the session explores the classification and parameters of supercapacitors, discussing their unique advantages over conventional energy storage technologies like batteries. Key topics include differences between technologies such as double-layer capacitors, pseudocapacitors, and hybrid systems, emphasizing their faster charging times, higher cycle lifetimes, and reliability in applications requiring consistent power delivery. A notable highlight is a demonstration of a hot-swappable backup solution measuring 10 cm x 18.5 cm (3.94 inch x 7.3 inches), designed for industrial power rail applications. The setup includes a 24V input and a 12V backup output delivering 30W (12V @ 2.5A), showcasing its practicality and efficiency.
The webinar also delves into critical aspects like the charge-, discharge-, and frequency behavior of supercapacitors, along with their model parameters and performance classifications. Würth Elektronik eiSos introduces several tools to support the design-in process, such as Support Note SN009, Application Note ANP077, and a forthcoming Supercapacitor bank calculation tool. Additionally, the power stage is demonstrated using the LTC3351 software from Analog Devices, underlining its precision in managing voltage balancing and performance optimization. By addressing real-world scenarios, such as power supply breakdowns, and equipping participants with design resources, this session offers valuable insights into enhancing system reliability with supercapacitor-based backup solutions.
