Improved topology of DC capacitors for differential mode noise mitigation in inverter

Résumé

This paper proposes improved decoupling capacitor topology in order to mitigate differential mode disturbance generated by inverter towards power supply. At first, a description of the setup used and its dedicated electrical model is made. This part allows validating the accuracy of the model. Then, frequency domain analysis is operated in order to explain each topology behavior regarding differential mode disturbance. The location of capacitors in the inverter is compared through frequency domain simulation on the one hand and experimental results on the other hand. An application is made by designing EMI filter, based on discrete LC components, and assessing efficiency involved by improved topology.
