Capacitors mutual inductance modeling and reduction

In this paper modeling of EMI filter capacitors and modeling of mutual couplings between them is presented. The modeling has been done using 3D electromagnetic software CST MWS. Three capacitor models have been proposed and verified experimentally. All proposed models during verification have shown that their performance is high enough to enable PCB mounted capacitor modeling and mutual inductance modeling between capacitors. Additionally several mutual inductance reduction techniques have been proposed, measured and modeled.
