Special Issue Information
Dear Colleagues,
Growing concern regarding the deterioration of the global environment has resulted in a rapidly increasing demand for renewable energy storage systems, such as solar power, wind power, and integrated energy storage systems. Efficient voltage conversion technology has therefore become increasingly crucial because these systems often operate at high or unstable voltage levels. Modern trends in the utilization of DC supply involve the development of DC microgrids, DC homes, and DC appliances. In such a context, deviating from the tradition of utilizing a DC-to-AC converter (inverter) with or without battery-based energy storage to buffer the fluctuations of DC bus supply, DC–DC converters with built-in energy storage are required due to their reliability.
DC-DC converters can be categorized into isolated and non-isolated types, with the primary distinction being the presence or absence of electrical isolation. Isolated converters use transformers to ensure electrical isolation between the input and output, which enhances the system safety. However, their circuit design is more complex compared with non-isolated converters. Non-isolated converters feature simpler structures but require extreme duty cycle operation to achieve high step-up or step-down voltage conversion. In addition, non-isolated converters offer notable advantages in renewable energy systems owing to their high efficiency and straightforward structure. The absence of bulky components like transformers results in a more compact and lightweight design, rendering non-isolated converters well-suited for space-constrained applications. Therefore, the simplicity of their topology and reduced component count effectively lower design and manufacturing costs, meeting the demands of cost-sensitive renewable energy systems. In all practical converters, (i) conversion efficiency, (ii) load regulation, (iii) line regulation, (iv) loop stability, (v) power density, and (vi) EMC compatibility are important design parameters.
This Special Issue focuses on advanced DC power converters for various energy systems.
