  • Increasing quality of SMPS through proper design of a high-Frequency Transformer
    International Journal of Power Electronics, 2020
    Co-Authors: Michal Frivaldsky, Pavol Spanik, Viliam Jaros, Andrej Kanovsky
    Abstract:

    High Frequency Transformer significantly influences power losses, power density and efficiency of isolated switched mode power supply. With the use of optimal design of high Frequency Transformer, the higher efficiency and power density can be achieved. This is necessary for fulfilment of the upcoming regulations and standards of the dc-dc converters. This paper deals with verification of the design procedure of high Frequency Transformer, which id oriented for the achievement of high efficiency of switched mode power supply. For verification purposes simulation models of dc-dc converter together with precise model of high Frequency Transformer are developed. The proposed procedure serves for optimal selection of the best solution for high-Frequency Transformer in terms of ferrite material as well as shape of magnetic core.

  • Rapid Design Procedure of High Frequency Transformer for Switched Mode Power Supply - Analysis and Verification
    International Review of Electrical Engineering (IREE), 2017
    Co-Authors: Michal Frivaldsky, Pavol Spanik, Viliam Jaros, Andrej Kanovsky
    Abstract:

    High Frequency Transformers significantly influence the operational characteristics and the efficiency of switched mode power supply. This paper deals with high Frequency Transformer optimized rapid design procedure. The procedure is based on the simplified design approach considering the most necessary phenomena related to high-Frequency Transformer operations. The verification is done through the simulation analysis of a dc-dc converter with a precise model of high Frequency Transformer. The simulation results serve to select the appropriate geometry of the Transformer in order to achieve the highest possible efficiency. The results are also verified by experimental measurements on the proposed LLC dual interleaved converter.

  • High-Frequency Transformer design for the soft-switching solid state Transformer (S4T)
    2017 IEEE Applied Power Electronics Conference and Exposition (APEC), 2017
    Co-Authors: Hao Chen, Deepak Divan
    Abstract:

    High-Frequency Transformer is a key element of the solid state Transformer. The high-Frequency Transformer for a patent-pending topology - soft-switching solid state Transformer (S4T) - has a unique feature of DC biased flux. This paper first evaluates the high-Frequency Transformer design using different high-Frequency magnetic materials. Then a new hybrid Transformer design methodology, which incorporates magnetic cores and permanent magnets, is also proposed. The permanent magnets provide pre-biased flux for the magnetics such that the usable B-H curve range is extended. Finite element analysis simulation and experimental verification show that the hybrid design can save magnetic materials by more than 50%.

  • Analysis of distributed parameters of 60 kV high-voltage high-Frequency Transformer
    Chinese Journal of Power Sources, 2011
    Co-Authors: Xue Xing
    Abstract:

    In high-voltage DC power supply,the high-voltage high-Frequency Transformer is the key component tostep up voltage,transfer energy and isolate circuits.Its performance directly affects the operation of the primary and secondary circuits.The distributed parameters of the high-voltage high-Frequency Transformer were leakage inductance and stray capacitance.Firstly,the mechanism of the stray capacitance in high-voltage high-Frequency Transformer was analyzed,and the equivalent circuit of four-winding high-voltage Transformer was introduced in thispaper.Secondly,the stray capacitance of the high-voltage high-Frequency Transformer was deduced by analytic approach according to its geometric parameters.And the dynamic capacitance of high-voltage high Frequency in thetwo different directions was compared.At last,a 60 kV high voltage high Frequency Transformer was designed,and its stray capacitance was tested.The result is in agreement with the theoretical value.
