High power density converter (HPDC) is important for more electric aircraft (MEA) applications, and high power density EMI filter is essential in HPDC systems, which suppresses EMI to meet the electromagnetic compatibility (EMC) requirement. Common mode choke (CMC) is a critical component of the EMI filter. Due to higher core loss and harsh operating temperature environment, thermal analysis of CMC...
This paper presents the extraction of common mode (CM) and differential mode (DM) inductances of a common mode choke (CMC) using 3D finite element method (FEM). For optimal performance of the CMC, the effects of CM and DM currents on the magnetic core saturation are investigated. As the parasitic capacitance of a CMC is a critical parameter that affects its high frequency performance, the parasitic...
