A High Frequency Equivalent Circuit and Parameter Extraction Procedure for Common Mode Choke in the EMI Filter
IEEE Transactions on Power Electronics, 2013Co-Authors: Carlos Cuellar, Xavier Margueron, Nadir IdirAbstract:Power converters with high switching frequency generate conducted electromagnetic interference (EMI) noise. EMI filters are thus widely used to reduce these conducted noises for the compliance with electromagnetic compatibility standards. In this paper, a high frequency (HF) equivalent circuit model for common mode (CM) Chokes used in EMI filters is proposed together with its parameter extraction procedure. This procedure is based on impedance measurements and it incorporates an iterative rational function approximation fitting algorithm to extract the parameters in the model. The proposed model and procedure is applied to a planar CM Choke which is used to realize an EMI filter. The simulated results of the filter show good agreement with the experimental ones. This extraction procedure is quite general and it can also be extended to identify the HF model of other passive components. Index Terms-Common mode Choke, electromagnetic interference filter, equivalent circuit, rational function approximation.

A Common-Mode Choke Using Toroid-EQ Mixed Structure
IEEE Transactions on Power Electronics, 2013Co-Authors: Carlos Cuellar, Xavier Margueron, Nadir IdirAbstract:Electromagnetic interference (EMI) filters are main solutions to suppress the conducted emissions from static power converters. For some years, integration techniques for EMI filters have been widely investigated to realize more compact systems. In this letter, a common-mode (CM) Choke with toroid-EQ mixed structure is presented. This structure is constituted of a toroidal CM Choke embedded into an EQ core. The proposed toroid-EQ CM Choke presents threefold advantages. First, it effectively increases the leakage inductance of the toroidal CM Choke and hence increases the differential-mode inductance. Second, it reduces the parasitic coupling between the Choke and the filter capacitors. Finally, the component can be easily fabricated with low cost. Experimental verifications have been carried out to validate the effectiveness of the proposed toroid-EQ CM Choke.

An integrated common mode and differential mode Choke for EMI suppression using magnetic epoxy mixture
2011 Twenty-Sixth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2011Co-Authors: Dushan Boroyevich, Paolo Mattevelli, David Gilham, Nicolas GazelAbstract:CM and DM Chokes are the majority parts in EMI filters, which take big portion of total system volume and weight. Integration technology can help on integrating the CM and DM Chokes together and reduce the total volume and weight, helps on improving power density of the converters. This paper proposed a CM /DM integrated Choke using magnetic mixture (magnetic gel). Applying the magnetic gel around the CM inductor can contain the leakage flux within the gel, so that it can help reduce the inductive coupling between EMI filter components. Simulation and experimental results show the potential of this material in magnetic integration.

common mode voltage in dc fed motor drive system and its impact on the emi filter
Applied Power Electronics Conference, 2010Co-Authors: Shuo Wang, Dushan Boroyevich, Fred Wang, Nicolas Gazel, Yong KangAbstract:Common mode (CM) Choke saturation is a practical problem in common-mode filter applications. It's generally believed that the leakage inductance of common-mode Chokes makes the core saturated. This paper analyzes two new mechanisms for common-mode Choke saturation due to common-mode voltage, and these mechanisms are verified in experiment. Common-mode Choke saturation is particularly important for motor drive systems, which have a high common-mode voltage and comparably higher stray grounding capacitance. A model is established to describe the relationship between the common-mode voltage and the volume of the common-mode magnetic components. According to the analysis, LISNs (line impedance stabilization networks) play an important role in the design of CM magnetic components.

First, small-signal measurement is carried out to demonstrate the design concept and the symmetry of the proposed structure. Then large-signal experimental results verify the attenuation characteristics, as well as the thermal performance.

Leakage Inductance Estimation of Toroidal Common-mode Choke from Perspective of Analogy between Reluctances and Capacitances
2020 IEEE Applied Power Electronics Conference and Exposition (APEC), 2020Co-Authors: Zhou Dong, Fred WangAbstract:To reduce the volume and weight of differential-mode (DM) inductors, the leakage inductance of a toroidal common-mode (CM) Choke is ofen used as partial DM inductance. However, the accurate prediction of the leakage inductance of CM Chokes through an analytical model is difficult, making the determination of remaining DM inductance difficult. This paper proposes a modeling method with the analogy between reluctances (or magnetic fields) and capacitances (or capacitive fields). The proposed method is verified by the leakage inductance comparison between the proposed model and simulation results for two CM cores with different turns numbers and wire gauges, and it demonstrated the proposed model can achieve the errors within 15% compared with simulation results for all cases.
