Special Issue Information

Dear Colleagues, 

The field of DC-DC converters has witnessed significant advancements in recent years, with applications in areas such as photovoltaic power generation, electric vehicles, DC microgrids, and home automation. Serving as a crucial interface between different DC sides, the performance of electric systems and industrial applications heavily relies on the capabilities of DC-DC converters. However, the advances made in DC-DC converters are not restricted to topologies and control techniques; research on materials and techniques for their optimization also plays a significant role in their development. This broadens the scope of exploration and innovation in the field. Advanced DC-DC converters, as key components in industrial applications, present challenges related to efficiency, cost, reliability, and power density. Topology and control strategies act as focal points in the research community's endeavors. For instance, the emergence of high-efficiency, high-reliability, and fault-tolerant topologies and control technologies sets the direction for such industrial application designs. Considering the aforementioned design targets, novel advancements in DC-DC converters encompass the exploration of novel materials, switching devices, and fault-tolerance techniques. These avenues of research aim to address the evolving needs and requirements of modern applications.

This Special Issue aims to delve into the realm of advanced DC-DC converter topology design, control, modulation, and applications. It invites researchers to contribute their insights and findings on a wide range of topics, including, but not limited to, the following:

  1. Novel material-based switching devices and components in DC-DC converters;
  2. Advanced or low-cost fault-tolerant control techniques for DC-DC converters;
  3. Reliability and security assessment of DC-DC converters;
  4. Emerging applications and advanced topology of DC-DC converters;

This paper proposes an isolated bidirectional dc-dc converter (IBDC) without a cooling fan with a low profile for a direct connection between a battery and the IBDC. To implement the low-profile IBDC, a dual active bridge (DAB) and two interleaved buck/boost converters are adopted in the proposed system. For the IBDC with a low profile and high efficiency, two transformers in the DAB converter are separated in series on their primary side and in parallel on their secondary side. In addition, in two interleaved buck/boost converters, their inputs and outputs are connected in parallel, and interleaving control is applied for a small total of inductor current ripple. Finally, a double heat sink is designed for excellent heat dissipation performance. A 500 W low-profile and fanless prototype with 650 V input and 1 (60 W)~5 V (500 W) output was made to verify its performance of operation, efficiency, and saturation temperature. Full article

Electric vehicles (EVs) are a sustainable means of transportation, with their onboard batteries being crucial for both performance and energy management. A modular and reconfigurable power converter topology to connect removable batteries to the main DC bus of an EV is proposed in this paper. By employing Dual Active Bridge (DAB) converters in an Input Parallel Output Series (IPOS) configuration, the proposed topology is compatible with 400 V and 800 V standards without the need for external switches. The research explored the possibility to apply a very simple control strategy based on independent linear regulators. A theoretical analysis of the IPOS DAB converter is presented and the design of independent control regulators which minimize the coupling effect between the control variables is addressed. The stability of the IPOS DAB converter could be ensured using the proposed simplistic approach, enabling us to drastically simplify the regulator design step. The dynamic performance of the system was confirmed by means of a simulation and experimentally. Full article

This study investigates the single transmitter and single receiver (STSR) with dual-output capability. This methodology utilizes dual half-wave rectification. Initially, the system topology of the STSR multi-channel voltage output is presented with the inductor-capacitor-capacitor-series (LCC-S) compensation topology, followed by an in-depth analysis of its double-channel voltage output characteristics. Through detailed analysis and empirical validation, the system is shown to maintain high efficiency and stable performance, making it well-suited for applications demanding reliable dual-voltage outputs under dynamic conditions.

This paper proposes a novel feedforward control scheme to achieve a very smooth transition from Constant Current (CC) to Constant Voltage (CV) charging modes, the commonly used method for electric vehicle charging applications. Furthermore, a three-loop model-independent Linear Active Disturbance Rejection Control (LADRC)-based system is proposed, replacing the traditional two-loop Proportional-Integral (PI) control system. The extra loop performs a decoupled dq vector control of the inductor current, which is typically not used in single-phase Dual Active Bridge (DAB) systems. This additional loop not only facilitates the optimal determination of both internal and external phase shift angles of a Dual-Phase Shift (DPS) modulator but also lowers the peak input current of the converter, allowing for lower-rated switches. Numerical simulations using MATLAB/Simulink demonstrate the robustness of the proposed control strategy against both input voltage disturbances and load disturbances during the transition from CC to CV charging modes. Hence, the dynamic performance of the charging system is significantly improved with minimal controller effort. Full article
