(Single Output 16th Brick) MODEL: ALD12/18/20/25 SERIES SHEET 17 OF 20 AUGUST 17, 2005 – REVISION C Input Filter for FCC Class B Conducted Noise A reference design for an input filter that can provide FCC Class B conducted noise levels is shown below (See Figure 42). Two common mode connected inductors are used in the circuit along with balanced bypass capacitors to shunt common mode currents into the ground plane. Shunting noise current back to the converter reduces the amount of energy reaching the input LISN for measurement. The application circuit shown has an earth ground (frame ground) connected to the converter output (-) terminal. Such a configuration is common practice to accommodate safety agency requirements. Grounding an output terminal results in much higher conducted emissions as measured at the input LISN because a hard path for common mode current back to the LISN is created by the frame ground. “Floating” loads generally result in much lower measured emissions. The electrical equivalent of a floating load, for EMI measurement purposes, can be created by grounding the converter output (load) through a suitably sized inductor(s) while maintaining the necessary safety bonding.
