Editorial 2021: Forward Together During a year when the only thing most of us seemed able to plan on were our plans changing, IEEE TRANSACTIONS ON POWER ELECTRONICS (TPEL) has continued without pause. Authors, reviewers, and editors have all pushed forward. While we all did our best to work from home, we submitted papers, we […]
Single-Switch Open-Circuit Diagnosis Method Based on Average Voltage Vector for Three-Level T-Type Inverter Fault-tolerant control strategy plays a significant role in improving the reliability of three-level T-type inverter where fault diagnosis method is the key and a research hotspot. Load power factor variation and modulation index regulation have great effect on conventional load current based […]
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 […]
Duty Cycle Loss Compensation Method Based on Magnetic Flux Cancelation in High-Current High-Frequency Synchronous Rectifier of LCLC Converter With uncertainty of the parasitic parameter in different practical layout, two synchronous rectifiers (SR) with same topology and identical components may exhibit significant difference in driving timing and each SR FET may suffers from the duty cycle […]
Selective Gate Driving in Intelligent Power Modules Due to practical limitations in the manufacturing of power semiconductor dies, high power modules are composed of several dies in parallel in order to meet the desired load current requirements. With careful attention to the design, modern insulated gate bipolar transistor (IGBT)-based power modules feature relatively balanced current […]
Successive-Approximation-Based Virtual Impedance Tuning Method for Accurate Reactive Power Sharing in Islanded Microgrids Due to the mismatched line impedances in islanded microgrids, distributed generation units with conventional droop tend to have barely satisfactory reactive power sharing accuracy. To handle this problem, this article proposes a virtual impedance tuning method based on successive approximation to accurately […]
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 […]
Design Method of PCB Inductors for High-Frequency GaN Converters The new power Gallium Nitride transistors allow to increase the operating frequency of converters to megahertz range, thanks to their low switching time that is of a few nanoseconds or less. This permits to reduce the values and the volume of the passive components, and enhance […]
Measuring and Separating Conducted Three-Wire Emissions From a Fault-Tolerant, NPC Propulsion Inverter With a Split-Battery Using Hardware Separators Based on HF Transformers Conducted emissions on the traction battery’s power cables in EVs must be limited to avoid unwanted electromagnetic interference (EMI). When designing an EMI filter, it is advantageous to have information of the common […]
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 […]
