Input Capacitor Selection for Power Supplies Video – Part 1

13.10.2023
Reading Time: 1 min read
A A

This is part 1 of 3 videos by Dr. Ali Shirsavar from Biricha about Input Capacitor sizing and selection for switch mode power supplies.

In this video we talk about why we need input capacitors, what roles ceramic capacitors and electrolytic capacitors play and we will show on an oscilloscope, how the noise on our input voltage changes with varying amount of capacitance.
