I want to design a low pass filter with common-mode choke that has a cutoff frequency of 100 Hz. This is going to be used in a bus 24V DC power system that will deliver 10A to the load. I want to use it to clear EMI, RF interference and noises. Since there is no AC line in a bus, 50 or 60 Hz noise will be no problem.
- Will Butterworth LC pi filter be a good choice?
- If so, I was given 470uH and 1.8mH common-mode chokes. How to calculate capacitor values?
- Will ouput impedance of the filter matter?
