Effect of height on power density in spiral-wound power-pot-core transformers

The effect of height on power density in spiral-wound power-pot-core transformers is examined for the practical range of power, frequency, loss, and volt-per-turn. Relevant mechanical and electrical equations are derived and applied to an optimization algorithm that searches for the design that maximizes the power density at a given height. It has been found that the curves of power density versus height exhibit a peak (on the order of 1000 W/in/sup 3/ in several cases) at a critical height between 0.25 and 0.3 in. Below this critical height, the power density decreases drastically.<
