Input Capacitor Selection for Power Supplies – Part 3: Electrolytic Capacitors

This is part 3 of 3 videos by Dr. Ali Shirsavar from Biricha about Input Capacitor sizing and selection for switch mode power supplies.

This is Part 3 of our 3 part video series on Input Capacitor Selection. In this video we will discuss how to calculate the size for our energy storage/bulk electrolytic capacitors including voltage rating and ripple current rating. We will then use REDEXPERT online tool to narrow down our choice down and select a suitable one.
