Kemet Video: Understanding Ripple Voltage Based on Different Types of Capacitors

William Mak, Kemet senior application engineer from KAIC lab demonstrates how four different capacitor types Aluminum, Aluminum polymer, Tantalum polymer and Ceramics affect the ripple voltage on a boost or buck regulator. Each technology of capacitors is compared using the KAIC-RCE-001 board, which uses the same output capacitance bank at the output of a switching regulator. However, the ESR and ESL differences of each technology cause a different output ripple voltage.
