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...
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...
This paper presents various strategies in a systematic way to reduce both differential mode (DM) and common mode (CM) noise using passive filter in a dc-fed motor drive. The type of grounding and components used is the key to a good design in order to optimize filter size and performance. Grounding schemes, materials comparison (ferrite vs. nanocrystalline core) and a new integrated filter structure...
This paper presents a comprehensive analysis studying the impact of interleaving on harmonic currents and voltages on AC side of parallel three-phase voltage source converters (VSCs). The analysis performed considers the effects of modulation index and the interleaving angle. Based on the analysis, the impact of interleaving on the design of AC passive components such as AC line inductor and EMI filter...
The charge control method is a suitable control scheme for achieving high switching frequency for the three-phase buck rectifier. Key improvements are made to the original control scheme allowing for input power factor compensation and the improvement of the input current waveform quality in the presence of an EMI filter. The modified control scheme is demonstrated using a 2 kW SiC JFET-based buck...
Direct current (dc)-link decoupling capacitors are normally used to control the voltage overshoot of switching devices in voltage source converters. This paper analyzes decoupling capacitors' impacts on device electromagnetic interference (EMI) noise as well as on device voltage stress. The design and selection of decoupling capacitors considering both voltage stress and EMI suppression are presented...
