Power Transformer Design. This Section covers the design of power trans- formers used in buck-derived topologies: forward converter, bridge, half-bridge, and full-wave center- tap. Flyback transformers (actually coupled induc- tors) are covered in a later Section. For more spe- cialized applications, the principles discussed
88. Review of Some Magnetic Concepts. • Units used in the design of magnetic components. • Current and magnetic flux. • Characteristics of magnetic materials. • Faraday's Law (the “transformer equation")
APPENDIXI. TRANSFORMER. DESIGN. In a discontinuous-mode flyback regulator, the first design step is to determine the maximum on-time of the power transistor. This determines the maximum "volt-second" product and affects the primary current. For the flyback regulator with constant power output and frequency
This “Cookbook" in hand shows you examples how to design and wind a transformer.
Some more advanced design issues, not considered in previous chapter: • Inclusion of core loss. • Selection of operating flux density to optimize total loss. • Multiple winding design: as in the coupled-inductor case, allocate the available window area among several windings. • A transformer design procedure.
In order to give insight to the reader, practical design examples are also provided. 2. General Transformer design procedure (1). Choose the proper core. Core type : Ferrite is the most widely used core material for commercial SMPS (Switchied mode power supply) applications. Various ferrite cores and bobbins are shown
For individual cores, WaAc is listed in this catalog under “Magnetic Data." The WaAc formula was obtained from derivations in Chapter 7 of A. I. Pressman's book, “Switching Power Supply Design. Choice of Bmax at various frequencies, Dcma and alternative transformer temperature rise calculations are also discussed in
Continuous Current Isolated, Buck-Boost Design Equations. 18. Design Example, Buck-Boost Isolated Converter Discontinuous Current. 19. Design Example, Boost Converter, Discontinuous Current. 20. Designing Boost Inductors for Power Factor Correction (PFC). 21. Standard Boost Flyback Converter. 22. Boost PFC
After completion of this lesson the reader will be able to: (i) Explain the underlying principles behind the design of a high frequency transformer and inductor. (ii) Do a preliminary design of a high frequency transformer for some popular configurations of SMPS circuits. (iii) Do a preliminary design of a high frequency inductor.
Switch mode power supply (SMPS) transformers are commonly used in a regulated power supply and func- tion to step up or step down voltage or current, and/or provide isolation between the input and output side of a power supply. On the primary side of a switch mode transformer, the duty cycle (on-time) of the input
