This is part 2 of 3 videos by Dr. Ali Shirsavar from Biricha about Input Capacitor sizing and selection for switch mode power supplies.
In this video we show how to calculate exactly how much ceramic capacitors capacitance we need on our input in order to reduce our input voltage ripple to a specified value. In the next part we will do the same for Electrolytics.
The first part of video with input capacitor function and introduction – see here:
