Advanced Design and Optimization in Power Converters and Power Transformers

Dear Colleagues,

Power conversion technology is widely used in electricity, mobile communications, military, medical, aerospace industries and other fields, involving all walks of life and forms of production. In particular, with the increasing awareness of environmental protection and independent energy security in recent years, many countries have vigorously developed renewable energy sources represented by wind and solar energy, and achieved large-scale grid connection. Power conversion technology plays an important role in the generation, transmission, distribution and equipment, which has significant research value and broad application prospects. So how to realize the efficient operation of power conversion unit under the premise of ensuring the economic reliability of the power system, and how to effectively control the power flow of the power system under the access of high proportion power converters have become the current research hotspot.

At present, both power converters and traditional power transformers have some shortcomings in performance that need to be optimized. For example, the power converters need to be further optimized for improving dynamic and steady-state performance, reducing switching loss and improving electromagnetic isolation ability. The insulation degradation and discharge mechanisms of power transformers under the action of electric-thermal coupling are still ambiguous. These problems are expected to be solved by designing and optimizing the topology structure and control. This Special Issue aims to exchange and discuss the advanced design and optimization technology of power converters and power transformers, power flow control and optimization method for stable and reliable operation of electrical power systems with high proportion power converters. This stimulates the innovative thinking and research enthusiasm of researchers and further promotes the development of power conversion technology and its application in smart grid.

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

• Optimized design of power converters and power transformers；
• Modeling and simulation of power converters and power transformers；
• Power conversion technology integrated energy storage；
• Application of power conversion technology in 5G communication base stations scenario；
• Application of power conversion technology in EVs charging station scenario；
• Application of power conversion technology in distributed energy resources and microgrids；
• Application of power conversion technology in ship power systems；
• Power flow control and optimization method for stable and reliable operation of electrical power systems with high proportion power converters.
