LINEAR Supercapacitors Can Replace a Backup Battery for Power Ride-Through Applications Design Note 450 Jim Drew

Update: 28 September, 2023

Supercapacitors (or ultracapacitors) are increasingly being used in applications that require short-term energy storage and intermittent high-energy pulses. This document introduces a power ride-through circuit application where a backup energy source switches in and powers the load during a short power supply failure. This application has traditionally been dominated by batteries, but electric double layer capacitors (EDLCs) are gaining traction due to their decreasing price-per-farad, size, and effective series resistance per capacitance (ESR/C).
