Special Issue Information

Dear Colleagues,

Power electronics is a major technology for energy conversion, energy conservation, and high functional energy use. Power semiconductor devices play a vital role in switching operations in power electronic technology. It is basically the application of electronics to the control and conversion of electric power. Nowadays, it is almost impossible to find an application without power electronics technology. We use power electronics for numerous everyday items, including fan controllers, air conditioners, induction cooktops, light dimmers, emergency lights, vacuum cleaners, personal computers, UPS systems, battery chargers, and many more.

Power converters are becoming increasingly necessary as more renewable energy harvesting methods are being developed, especially for processing large volumes of power. The following are some very general categories in which the current power electronics research is being conducted:

  • Solar and wind energy: Since these natural sources must transfer and carry large amounts of power over great distances, more effective power electronic equipment is needed.
  • Power quality: Modern loads like electric cars and batteries draw power that is extremely nonlinear, which has an impact on the quality of the electricity. As a result, the employment of active filters and FACTS devices is a well-established and expanding research topic.
  • HVDC transmission systems: Nowadays, HVDC and EHV transmission systems are widely used due to the ever-increasing need for power. Higher transmission efficiency is required now more than ever to cut losses and save millions of dollars with the advent of the votage source inverter (VSI) and fully controlled switches.
  • Electric vehicles: The basic components of electric vehicles are battery, battery charging systems, power converter, motor, and power distribution systems. Since driverless cars in the future will all be zero-emission vehicles, this market is quite promising. The domain occasionally combines with machinery, controls, and communication systems.
  • Electric machines and drives: These are significant areas of research that are always vital. The list includes everything from multiphase machines to magnetic bearings, linear induction machines, open-end winding, and further aircraft. Many more areas might be included in this list, making power electronics and machine drives a particularly promising topic for future technological improvements.

In summary, there are some evergreen research topics related to power electronics such as renewable integration, harmonic performance of electric drives, predictive control in power electronics, multi-level converters and high-power drives, reliability of power electronics, SiC/GaN devices, filter design, energy storage, etc., solid state transformers, power quality, and many more.

This article presents a control method for an isolated bidirectional dual active bridge DC–DC converter (IBDC) where single phase shift (SPS) and variable frequency (VF) modulations are combined simultaneously with the purpose of improving the efficiency of the converter applied to the bidirectional charging of electric vehicles batteries. A complete power characterization of the dual active bridge (DAB) converter is carried out. The combined control achieves lossless turn-on and turn-off on the primary bridge for a wide range of output powers. A comparative study of power losses between the traditional SPS control and the combined method proposed here was also carried out. A prototype with an output power of 10 kW was built based on Silicon Carbide (SiC) Metal Oxide Semiconductor Field-Effect Transistors (MOSFET), with which a peak efficiency close to 99% was obtained, thus verifying the viability of the method.

As the penetration of renewable energy increases year by year, the risk of high-frequency oscillation instability increases when a three-phase, four-wire split capacitor inverter (TFSCI) is connected to the grid with complementary capacitors in weak grids. Compared to the three-phase, three-wire inverter, the TFSCI has an additional zero-sequence current loop. To improve the accuracy of the modeling and stability analysis, the effect of the zero-sequence loop needs to be considered in the impedance-based stability analysis. Therefore, a correlation model considering multi-perturbation variables is first established, based on which the inverter positive, negative, and zero sequence admittance models are derived, solving the difficult problem of impedance modeling under small perturbations. Secondly, an admittance remodeling strategy based on a negative third-order differential element and a second-order generalized integrator (SOGI) damping controller is proposed, which can improve the stability of positive, negative, and zero-sequence systems simultaneously. Finally, the effectiveness of the oscillation suppression strategy is verified by simulation and experiment. Full article

Parasitic oscillations in the rectifier diode voltage of phase-shifted-full-bridge (PSFB) converters limit their application in high-voltage and high-power situations. The conventional analysis method for parasitic oscillation in rectifier diode voltage in PSFB converters treats the filter inductor as a constant current source and fails to consider the impact of changes in filter inductor current on the rectifier diode’s parasitic oscillation. Consequently, this approach does not apply when analyzing the rectifier diode voltage’s parasitic oscillations in high-power PSFB converters employing an input-parallel output-series (IPOS) configuration with interleaved drive. This research paper introduces an innovative equivalent circuit model for analyzing the parasitic oscillations of rectifier diode voltage in IPOS high-power PSFB converters. The model takes into account the mutual influence of rectifier diode voltage oscillations between submodules under interleaved control, considering the influence of changes in filter inductor current on rectifier diode parasitic oscillation. Based on the circuit model, we explain the mechanism of multiple oscillations of the rectifier diode voltage and the reason for the high peak of the first oscillation. Consequently, the interplay of rectifier diode voltage oscillations in IPOS high-power k-module PSFB converters under interleaved control is analyzed. To mitigate the adverse effects of rectifier diode voltage parasitic oscillation, a buffering strategy involving the connection of a resistor capacitor diode (RCD) circuit in parallel after the rectifier bridge is adopted, considering the structure of the IPOS high-power PSFB converter. The study provides a detailed analysis of the circuit’s operation mechanism upon incorporating the RCD buffer circuit and establishes the relationship between buffer capacitance, resistance, and spike voltage. Furthermore, a design method for buffer capacitors and discharge resistors in buffer circuits is presented. Finally, a 100 kW prototype is tested to verify the rectifier diode voltage oscillation mechanism of the IPOS high-power PSFB converter and the rationality of the buffer capacitor and discharge resistor design method under the interleaved drive approach.

Significant circulating currents in the modular multilevel converter (MMC) increase system losses and complicate heat-sink design. Conventional PI and PR controllers can achieve steady-state error adjustment, but are sensitive to parameter changes and model uncertainty, heavily relying on coordinate transformations and careful design of model parameters. Model predictive control (MPC) has the characteristics of simple design, good robustness, and excellent dynamic response; however, it encountered the complexity of adjusting weighting factors. This paper proposed circulating the current model predictive proportional integral control (MPPIC) method in abc reference frame. This hybrid control solution utilized the predictive model and traditional PI algorithm to combine the advantages of nonlinear and linear control. Compared with existing suppression methods, this method avoided complex mathematical operations and a selection of weight coefficients, was easy to implement, and can effectively suppress circulating currents under different modulation ratios. Simulations were conducted on MATLAB/Simulink to verify the effectiveness of the proposed control strategy. MPPIC can not only distinctly suppress the circulating currents, but also reduce the overall voltage fluctuation of sub-modules capacitors under different modulation ratios, and had almost no any adverse effect on the performance of MMC.
