Special Issue Information

Dear Colleagues,

We are pleased to share the success of our Special Issues “Electric Machinery and Transformers” and “Electric Machinery and Transformers II”.

In the first volume, we successfully published 12 papers: https://www.mdpi.com/journal/energies/special_issues/Electric_Machinery_Transformers

In the second volume, we successfully published 7 papers: https://www.mdpi.com/journal/energies/special_issues/O0245FP2QJ

We are now preparing to launch the third volume of this Special Issue, “Electric Machinery and Transformers III”.

With rapid developments in materials and semiconductor devices, electric machines and transformers have evolved considerably over the past 10 years and have been used in new applications, such as in e-mobility, aerospace technology, and renewable energy production, where stringent requirements for a high power density, low weight, compact size, and low cost should be met. Thus, it is a necessity to establish new paradigms to design, construct, and select materials and drive systems for electric machines and transformers. Therefore, the purpose of this Special Issue is to facilitate a platform for disseminating new findings on any aspect of electric machines and transformers.

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

  • New materials used in electric machines and transformers;
  • Novel designs for electric machines (synchronous motors and generators, brushless DC motors, induction motors, and conventional DC motors) for applications such as drive-by-wire, fly-by-wire, renewable energy production from wind farms, and precision control systems;
  • The design of low-frequency, high-frequency, and pulse transformers for various applications;
  • The development of mathematical models to investigate the performance of electric machines and transformers in a dynamic state as well as in a steady state;
  • Discussions of new methods for design optimization in electric machines and transformers;
  • Novel drive systems to increase the operation performance of electric machines;
  • The prediction of the time to failure of the insulation in large electric machines and transformers;
  • Studies of the thermal behavior of electric machines and transformers for various applications;
  • Acoustic analyses of electric machines and transformers using vibrations;
  • The continuous monitoring of the state of magnetic, as well as insulating, materials in electric machine and transformers during operation.

We welcome your submissions.

Accurately calculating winding losses has always been a significant challenge in the design of large-capacity medium-frequency transformers. This paper presents an accurate design algorithm for calculating the winding losses of a large-capacity medium-frequency distribution transformer. First, the peculiarities of winding losses in medium-frequency distribution transformers are analyzed. Various commonly used winding conductor types for medium-frequency transformers are introduced. The mechanisms of and differences between AC and DC winding losses in medium-frequency transformers are explained, and an effective analytical method for calculating the AC-to-DC resistance ratio is provided. Finally, the analytical calculation results of different types of winding losses are compared with those obtained through finite element simulations and experimental methods applied to a real transformer prototype. The discrepancies between the analytical results and those obtained using the other two methods were found to be within acceptable error margins, thereby validating the accuracy and effectiveness of the proposed algorithm.
