This article investigates the potential of the emerging flexible multilayer foils (FMLFs)-based winding design to promote magnetic integration technique in power electronic systems. Through full integration of a single-phase electromagnetic interference (EMI) choke, the common-mode (CM) and differential-mode (DM) filtering elements can be combined into the same core unit. Experimental measurements demonstrate the effectiveness of the proposed model.
The emerging flexible multilayer foils (FMLFs)-based winding design has a great potential to promote the magnetic integration technique in power electronic systems. This article investigates the full integration of a single-phase electromagnetic interference (EMI) choke with well-designed FMLFs. By sharing a UU-type core and configuring the windings reasonably, all the common-mode (CM) inductance and capacitances and differential-mode (DM) inductances and capacitances can be integrated into the same core unit. Moreover, the proper terminal configuration of conductive layers can realize function-decoupling between CM and DM filtering elements, which contributes to simplifying the equivalent CM and DM models, then predigesting the parameters design procedure. Following the modeling and theoretical analysis, prototypes of the proposed and existing EMI chokes have been built for a single-phase 200-kHz SiC-mosfet inverter system. Through experimental measurements, performance comparisons have been presented to demonstrate the validity of this model.
