Design of high frequency transformers in different shape of core using matlab program

Abstract

<p>This paper deals with the design, simulation and implementation<br />of the high-frequency transformer for a push-pull converter. It<br />also includes transformer design and simulation for two switches,<br />two outputs forward converter. Design these transformers by<br />building a program, this program is designed in MATLAB<br />software using a graphical user interface (GUI). The program is<br />aimed to reduce the efforts and reduce the time compare with the<br />manual design which takes time and effort. This paper provided<br />the shape and geometry of the core that can influence the<br />efficiency of the converter by designing these transformers in two<br />types of core. The design results were validated by simulation in<br />power simulation software (PSIM), and compare the results of<br />simulation and design.</p>

Investigating and calculating the temperature of hot-spot factor for transformers

“…Nevertheless, another such distinction among ohmic wind and stray losses is important since the stray losses arise in various parts of the transformer [8] and hence have only a slight influence on the intensity of the winding. Consequently, the temperature is primarily influence by losses in ohmic winding [9]- [11].…”
