Understanding Ripple Voltage Based on Different Types of Capacitors

From KEMET Application Intelligence Center (KAIC), William demonstrates how four different capacitor types 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. The capacitor types used in this video are listed below:
