SELECTING PROPER CONNECTION POINTS FOR Y-CAPACITOR TO REDUCE EMI IN SMPS

Y-capacitors are used to reduce electro magnetic interference (EMI) in SMPS. This is a capacitor connected between primary and secondary of the SMPS transformer to bypass EMI currents and thus preventing them to reach mains port. Proper connection points for this capacitor are discussed and experime...

Description
Summary:Y-capacitors are used to reduce electro magnetic interference (EMI) in SMPS. This is a capacitor connected between primary and secondary of the SMPS transformer to bypass EMI currents and thus preventing them to reach mains port. Proper connection points for this capacitor are discussed and experimental results are analyzed to verify their effectiveness.
