Special Issue Information

Dear Colleagues,

With advances in converter topologies and wide-band-gap (WBG) devices, new-generation power conversion technologies gained gain unprecedented attention for significant margins in energy saving, high compactness, high functionality, and reliability. Their use has been gradually developed from low-voltage power converters to medium-/high-voltage fields, including fast chargers, data centers, electric vehicles, renewable energy integration, HVDCs, electric ship, aircraft, aerospace, etc. However, three challenging issues hinder the development of the so-called next-generation power converter technologies: 1) novel topologies, modeling, and the control of power converters to maximize the benefits of WBG devices; 2) the sophisticated design and integration of power electronic devices, circuits, and systems to realize high power densities; 3) the intelligent monitoring, operation, and health management of power converters to enhance the reliability and lifespan. Solving those issues can accelerate the development of new-generation power conversion technologies.

This Special Issue aims to present and disseminate the most recent advances related to the topology, modelling, control, design, analysis, and online monitoring of all types of power converters, especially the application of SiC and GaN devices.

Topics of interest for publication include, but are not limited to, the following:

  • Novel topologies of dc/ac, ac/dc, dc/dc, and ac/ac conversion;
  • Modelling and control of two-/three-/multilevel converters;
  • Modeling and control of high-power motor drives, solid-state transformers, HVDCs, etc.;
  • Fault-tolerant and smart condition monitoring technologies;
  • Power electronic devices, gate drivers, and integrated circuits for WBG devices;
  • The design of high-performance power converters with SiC and GaN devices;
  • Optimization towards passive components including capacitors, magnetics, and cooling assembly;
  • The application of WBG devices in energy storage, renewable energy integration, electric ship/train/aerospace, etc.

We are looking forward to receiving your outstand work for this Special Issue.

This paper investigates the current sink capacitor technique as a method to minimize the turn-off power losses of SiC MOSFETs operated with zero-voltage switching (ZVS). The method is simple and is based on adding auxiliary capacitors in parallel to the transistors, allowing the sink capacitor to take over part of the channel current, thus limiting the power loss while also advantageously lowering the dvds/dt ratio. The technique is validated and experimentally studied based on a single-pulse test setup with 1200 V-rated SiC MOSFETs, with several capacitances and gate resistance values, at various switched currents up to roughly 60 A. It is shown that by employing even very small capacitances, in the range of nanofarads, the turn-off power loss can be reduced by over tenfold, with a negligible impact on the volume and complexity of the system. Thus, the presented method can be effectively employed to improve soft-switched power converters. Full article

The modular multilevel converter (MMC) is recognized as one of the promising converters for the electrification of ships and railways. Among different energy conversion stages, the MMC-based rectifier should realize stable DC output voltage and accurate input current control. However, output DC-bus voltage sensors must be installed, which are costly and bulky. This paper presents a simple but effective control method for the MMC-based rectifier, removing the traditional output DC-bus voltage sensor. An accurate evaluation model of DC-bus voltage is developed as well as the implementing method. Meanwhile, a safe and fast pre-charging scheme is presented for the MMC-based rectifier without output voltage sensors. The fault-tolerant capability of the proposed method when the failure of the output DC-bus voltage sensor occurs is examined. Simulated and testing results demonstrate that the proposed method presents not only excellent steady-state and dynamic performance but also strong fault-tolerant capability. The proposed evaluation model for DC-bus voltage has a high accuracy with an error of less than 1%. Besides, the pre-charging time is less than 0.5 s using the proposed sensorless control.
