Special Issue Information

Dear Colleagues,

Environmental pollution and the energy crisis promote the development of emerging power electronic systems, which show a wide range of application prospects. Following this trend, the sustainable energy represented by photovoltaic and energy storage, and the clean load represented by electric vehicles (EVs), have been experiencing booming advancements in the last decade. To enable newly emerging applications and technologies, power conversion topologies, control methods, and nonlinear modeling and stability analyses play a pivotal role. Furthermore, emerging power conversion applications, such as green buildings, EV fast-charging stations, and data centers, also put forward higher requirements for high efficiency, high power density, high stability and reliability, fast transient response speeds, and other performance factors.

This Special Issue is devoted to the state-of-the-art technologies of "Advanced Topologies, Control Methods, and Nonlinear Dynamics for Emerging Power Electronic Systems", encompassing new power electronic topologies, advanced control technology, and nonlinear dynamic modeling and analysis. Prospective authors are invited to submit original contributions or survey papers for review for publication. Topics of interest include, but are not limited to, the following:

  • High-performance power conversion topologies: analysis, design, and implementation of advanced topologies, soft switching, high efficiency, high power density, magnetic integration, and high voltage gain.
  • Topology and control of multiport converters: topological derivation theory and methods for multiport converters, bipolar dc–dc topologies and control methods, control techniques of multiple-output dc–dc converters, modeling analysis and power flow optimization control, and multisource coordinated control methods.
  • Advanced control for power electronic systems: emerging model predictive control methods, modeling and design of controllers, advanced maximum power point tracking (MPPT) algorithm, power factor correction, wide ac input frequency, and unbalanced ac input/output.
  • Advanced power electronics for energy storage: control of hybrid energy storage systems, battery management systems, emerging algorithms for state-of-charge (SOC) estimation, and bidirectional dc–dc converters.
  • Nonlinear dynamic modeling and analysis: bifurcation analysis, dynamic modeling, stability analysis, and nonlinear control systems.

In this paper, based on the pseudo-totem pole (PTP) circuit, a family of five-level PTP dual boost converters (PDBC) is proposed. A dual boost converter has some unique advantages, such as having no risk of bridge arm shoot-through and no problems related to switch body diode reverse recovery; thus, it has a good potential for applications. First, the derivation process, working principle, modulation and strategy of the topology are analyzed. Further, the number of power devices, switch voltages and current stress of the proposed topology is analyzed. Finally, a representative five-level PDBC experimental prototype is designed with AC input 220 V/50 Hz, DC output 400 V/1 kW, and peak efficiency of 98.27%. The experimental results show that the five-level PDBC proposed in this paper has higher efficiency and the correctness of its topology is verified. Full article

When the input inductor operates in discontinuous current mode (DCM), the Cuk converter can automatically achieve power factor correction (PFC) function with only a simple voltage mode control loop. However, the conventional Cuk PFC converter suffers from high intermediate capacitor voltage because of the lack of feedback of the intermediate capacitor voltage and relatively low power factor (PF). In this paper, a Cuk PFC converter using variable inductor which varies with the transient rectified input voltage is proposed to enhance the PF and reduce the intermediate capacitor voltage by injecting a controlled DC bias current into the auxiliary winding of the variable input inductor. The operating principles of the proposed Cuk PFC converter based on variable inductor are analyzed in detail, and the analysis of PF, the voltage of intermediate capacitor, and design considerations are provided. To verify the feasibility of the proposed scheme and compare the characteristics of both the traditional and proposed Cuk PFC converter, a 108W experimental prototype of the proposed converter is built and tested. The experimental results show that the proposed Cuk PFC converter can significantly enhance the PF, decrease the intermediate capacitor voltage, and increase efficiency compared with the traditional Cuk PFC converter.

In this paper, a family of a novel single-phase three-level PFC based on a switch-capacitor cell is proposed. The proposed PFC topologies have the characteristics of high power factor, low voltage stresses, and low power losses. Firstly, the derivation process of the novel PFC topologies is introduced in detail. Based on a representative circuit of the proposed novel PFC topologies, its operation principle is analyzed from the aspects of working current paths, key waveforms, and pulse distribution. Meanwhile, its equivalent circuit model is deduced. Secondly, the performance of the proposed PFC topologies is analyzed. Then the modulation technology based on capacitor voltage balancing is designed for the proposed topologies. Finally, an experimental prototype with a rated power of 800 W and a DC output voltage of 400 V is built. The experimental analysis is carried out from both the steady state and dynamic state. The experimental results verify the feasibility of the proposed novel three-level PFC topologies and the effectiveness of the modulation technology. Full article

With the large-scale centralized penetration of renewable energy represented by wind turbine and photovoltaic power generation, the equivalent inertia and synchronous torque of traditional power grids have decreased, which is worsening the frequency dynamics and threatening the stability and reliability of power grids. Virtual synchronous generators (VSGs) are a type of grid-friendly inverter in microgrids (MGs) that mimic rotational synchronous generators (SGs) to maintain system stability with the increasing penetration of power electronic converters. In this paper, the stability analysis method of one type of VSG, synchronverter, is investigated based on internal voltage dynamics. The torque components affecting the stability mechanism of synchronizing, inertia, and damping torque is introduced, which offers a physical insight into transient stability and dynamic performance. Insufficiency in either damping or synchronizing torque would increase the unstable possibility. The characterization method of stability mechanisms can be illustrated by the phasor diagram of synchronverter internal voltage. Some cases under different disturbances which change the pattern of synchronizing and damping torque and in turn influence the internal voltage dynamics of synchronverters, are also discussed. In addition, an auxiliary correction control loop is proposed and added in the synchronverter control loop to enhance the robustness of the synchronverter against disturbances. The tunable coefficient of the correction loop is analyzed based on the internal voltage method. Simulation results verify the validity of the internal voltage stability method in synchronverters.
