Hybrid Passive Cancelation Method for Reducing Common-Mode Noise in Isolated Power Converters

June 15, 2020L. Xie, X. Ruan, H. Zhu, and Y.-K. LoEMI/EMC

Hybrid Passive Cancelation Method for Reducing Common-Mode Noise in Isolated Power Converters The shielding technique is an effective method for reducing the common-mode (CM) electromagnetic interference in an isolated power converter. However, the interwinding capacitance between the shielding layer and its adjacent winding provides the path for CM noise current. This CM noise current can […]

June 9, 2020W. Tang, K. Ma, and Y. SongPower Quality and Utilities

Critical Damping Ratio to Ensure Design Efficiency and Stability of LCL Filters The resonance of LCL filter gives challenge to the control stability of LCL-filter-based converter systems. To suppress the filter resonance, damping methods are widely adopted. Nevertheless, the determination of damping parameters for LCL filters can be vague, insufficient or excessive, because the filter […]

June 5, 2020J. Xue, Z. Xin, H. Wang, P.C. Loh, and F. BlaabjergLetters

An Improved di/dt-RCD Detection for Short-Circuit Protection of SiC mosfet Silicon carbide metal-oxide-semiconductor field-effect transistor has a smaller short-circuit tolerance, and hence, requires faster and more accurate short-circuit protection. One prospective method is to combine fast di/dt detection with an integration circuit. The former is for detecting the extremely fast increase of short-circuit current, while […]

Grid Inertia Support Enabled by Smart Loads

June 2, 2020Y. Qi, T. Yang, J. Fang, Y. Tang, K. R. R. Potti, and K. RajashekaraControl in Power Electronics

Grid Inertia Support Enabled by Smart Loads The increasing penetration of renewable energy resources (RESs) leads to a continuous displacement of synchronous generators. Since the grid integration of RESs is usually achieved through inertialess power converters, the system inertia reduces and the power system frequency stability is compromised. Consequently, unexpected generator tripping, load shedding, and […]
