A New Analytical EMC Model of Power Electronics Converters based on Quadripole System: Application to Demonstrate the Mode Decoupling Condition
Résumé
This paper proposes a new general method to
model converters by a four-terminal circuit which consists in a π-
quadripole network containing three impedances between each
pair of electrical access, L to N, L to G and N to G. The
impedances analytical expressions have been established using
quadripole theory, and depend both on the converter switching
function and impedances. The analytical method developed is
applied on a DC-DC converter and validated with PSpice
simulations and an experimental measurement. This approach is
applied to highlight the condition of the common mode and
differential mode decoupling.
