I am working on designing an EMI input filter, and I was wondering how I should go about choosing a value (capacitance) for the X-capacitor. I found a post (linked below) which talked about calculating the power factor, and then choosing a cap that gave you a decent power factor (without being too greedy.)
The best line capacitor to maximize power factor to a value of 1 is when you don''t use a line capacitor. Any line capacitor will degrade the power factor of an SMPS. I''ll quote what you linked: - the minimum value is based on the actual conducted EMI and what levels are acceptable for your application.
