Special Issue Information

Dear Colleagues,

The Guest Editor is inviting submissions for a Special Issue of Processes on the subject area of “Power Electronic for Photovoltaic Systems”.

Power electronics is used in a wide range of applications today, for example, photovoltaic systems, wind systems, smart grid, saving-energy illustration, distributed energy systems, power converters, etc. Power electronics is already a part of the green industry, and it plays a relevant and key role. Especially in recent years, with the vigorous development of green energy, the integration of power electronics and green energy is an inevitable trend, and AI, the Internet of Things (IOT), and cloud have even been added, on top of other technologies, making the future development of power electronics more exciting.

Research in this field investigates several topics, including but not limited to power electronic technologies, DC–DC converter technologies, DC–AC inverter technologies, photovoltaic systems, smart grid, saving-energy illustration, distributed energy systems, energy storage systems, energy transmission systems, electric vehicles, and renewable energy applications.

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

  • Innovative power converter topologies;
  • Power electronic for photovoltaic systems;
  • Power converters suitable for wireless power transfer;
  • Power electronics for electric vehicles;
  • Switching converters in smart grid applications and energy transmission systems;
  • Power converters for energy storage systems;
  • Power converters for e-mobility;
  • Power electronic for renewable energy conversion;
  • Power converters for LED driving circuits.

This paper presents a soft switching direct current (DC) converter, with the benefits of bidirectional power conversion and wide-ranging voltage operation for battery charging and discharging capability. A series resonant circuit with variable switching frequency modulation is used to achieve the advantages of soft switching turn-on or turn-off of semiconductor devices. Therefore, the switching power losses in power devices can be reduced. A symmetric resonant circuit topology with a capacitor–inductor–inductor–capacitor (CLLC) structure is adopted to achieve a bidirectional power conversion capability for battery storage units in electric vehicle applications. Due to the symmetric circuit structure on both input and output sides, the converter has similar voltage gains for each power flow operation. In order to overcome the drawback of narrow voltage range operation in conventional resonant converters, a variable transformer turns ratio is adopted in the circuit, to achieve wide output voltage operation (150–450 V) for battery charging applications. To demonstrate the converter performance, a 1-kW laboratory prototype was constructed and tested. Experimental results are provided, to verify the effectiveness of the studied circuit. Full article

This paper presents a novel bidirectional DC–DC converter, equipped with a three-winding coupled inductor, that can be applied to high-voltage, bidirectional DC–DC energy conversion and meet battery charging and discharging requirements. The architecture consists of a semi-Z-source converter and a forward–flyback converter featuring a three-winding coupled inductor with an iron core. This proposed topology retains the current continuity characteristics of the low-voltage side, all switches possess the zero-voltage switching feature, and the switches on the low-voltage side in the step-down mode have a synchronous rectification function. A 500-W bidirectional converter is implemented to examine the practicality and feasibility of the proposed topology. The relatively streamlined design of the converter can greatly reduce production costs. In the step-up and step-down modes, the maximum energy conversion efficiencies are 95.74% and 96.13%, respectively. Full article
