Abstract
Switching circuits, operating at high frequencies, have led to considerable reductions in the size of magnetic components and power supplies, Nonsinusoidal voltage and current waveforms and high-frequency skin and proximity effects contribute to transformer losses. Traditionally, transformer design has been based on sinusoidal voltage and current waveforms operating at low frequencies. The physical and electrical properties of the transformer form the basis of a new design methodology while taking full account of the current and voltage waveforms and high-frequency effects. Core selection is based on the optimum throughput of energy with minimum losses. The optimum core is found directly from the transformer specifications: frequency, power output, and temperature rise. The design methodology is illustrated with a detailed design of a push-pull converter.
