How do you increase the capabilities of EMI/EMC?

• For Surge/EFT part

          Connect E-Cap, TVS, MOV, Gas Discharge Tube (GDT) in parallel at input side.

• For EMI part

         - Increase the inductance, capacitance of π filter.

         - Increase the common mode choke inductance.

         - Connect Y-Cap on the primary and secondary sides of DC/DC converter.
