Analysis of Electromagnetic Characteristics of High Frequency Transformer Based on C Type Nanocrystalline Magnetic Core

With the rapid development of future grid technologies such as smart grid and energy internet, power electronic transformers with various functions such as voltage transformation, electrical isolation, power regulation and control, and renewable energy access can be realized. Relevant theories and technologies have been studied. More and more attention. However, from the overall point of view, the topology and design structure of the three major parts of the power electronic transformer (input stage, isolation stage, output stage) have great problems for the overall application. In this paper, the high-frequency transformer of the isolation stage is used in the middle of the power electronic transformer. The C-type nanocrystalline magnetic core is used to design the high-frequency transformer. The modeling of the transformer is completed in COMSOL, and the equivalent modeling of the winding is used to combine with the external circuit. The simulation analysis method is carried out and the high-frequency transformer is simulated and analyzed to study its feasibility.
