I would like to know how to select a common mode choke inductance value for EMC filter design for DC -DC power supply
The Specifications are :
Cutoff frequency : 20 Khz
Power suppply Maximum Current : 2A
Power suppply voltage : 24V
Required Impedence : Maximum Noise must be attenuated.
EMC test Environment immision : 450 Mhz
I am learning about power supplies , EMC Filters so kindly help me in this so that it would be a helpfull for my knowledge.
