Special Issue Information

Dear Colleagues,

Power DC–DC converters have become the main branch of power electronics, mainly due to the innumerable applications and power ranges where they are used. DC–DC converters are present in high-power systems such as DC motor drivers, uninterruptible power supplies (UPSs), Switched-mode power supplies (SMPSs), renewable energy sources (RESs), hybrid/electric vehicles (HEVs/EVs), distributed generation (DG), energy storage systems (ESSs), smart grids (SGs), micro-grids (µGs), and many more. They are also used in low-power applications such as cellular phones, Internet of Things (IoT), some low-power smart systems, and medical applications.

With this Special Issue, we intended to cover a wide range of topics that comprise the field of DC–DC power converters, which will be of interest to a broad number of professionals of the industry and academia who are involved in the research, development, and use of this type of converter. Therefore, we aim to include papers that present emerging trends and practices on DC–DC power converters, reports on product research and development, key insights, as well as tutorials and surveys covering the theory and application of these converters. Particular emphasis will be on reports of the development, deployment, and trends of recent technology.

Topics of interest related to the research, development, and trends of DC–DC power converters include, but are not limited to, the following:

  • Traditional, current, news, and emergent applications.
  • High-, medium-, or low-power/current/voltage. Isolated and non-isolated DC–DC power converters.
  • Efficient, compact, and smart power management, monitoring, IoT, Industry 4.0, and smart DC–DC power converters applications.
  • DC–DC converters in plug-in electric vehicle charging stations.
  • Wide-range DC–DC converters. Input and output voltage range, power, or load range.
  • DC–DC converters based on wide bandgap switches.
  • Multiport DC–DC power converters: SISO, SIDO, MISO, MIMO, and SIMO.
  • Multiphase interleaved DC–DC power converters and multilevel DC–DC Power converters.
  • Soft- and hard-switching DC–DC converters: MRCs, QRCs, and PWM.
  • Low-voltage, high-efficiency, and high-power-density DC–DC converters.
  • Control strategies, modeling, and simulation.
  • State of the art and reviews on DC–DC power converters and applications.

This paper presents an approach to designing a supercapacitor (SC) module according to defined power profiles and providing a control algorithm for sharing the energy from the SC module and accumulator in a hybrid energy storage system (HESS). This paper also presents a view of a printed circuit board (PCB) of the SC module and an interconnection board between the bidirectional converter, accumulator, and SC module. The practical part of the paper presents the measurement of the voltages and currents on the SC module, accumulator, and output of the DC/DC converter to visualize the energy flow between them.

This work presents a comparative study of a step-down converter controlled through the algorithm MPPT Perturb and Observe (P&O) with or without a fuzzy logic controller supplied by a photovoltaic system. This study aimed at increasing the quantity of electric energy taken over from the photovoltaic systems by the load through the DC-DC convertor. To follow up the maximum power point where the transfer is performed from the photovoltaic system to the load at maximum power, the Perturb and Observe (P&O) method was used. Two programs were elaborated in MATLAB-Simulink R2018a to control the buck convertor commanded through the P&O algorithm with or without a fuzzy logic controller. The analysis of the results showed that a higher quantity of energy is transferred from the source to the receptor circuit in the case of the buck convertor controlled through the P&O algorithm with a fuzzy logic controller. The P&O algorithm was implemented on an experimental stand at the Laboratory of Electrical Machinery and Drives of the Engineering Faculty in Bacau, with the help of a program issued in the Arduino IDE programming environment. The analysis of the results showed that for an increase in the power conveyed to the receptor circuit, there will also be an increase in the filling factor of the PWM signal that controls the power transistor in the structure of the DC-DC convertor. The P&O algorithm with a fuzzy logic controller may also be implemented in the DC-DC converters in the structure of the driving systems of electric vehicles. Full article
