A planar parametric transformer has several desirable features, including voltage regulation, overload protection, and noise rejection. We examined various transformers of different sizes and movement frequencies. The characteristics of the transformers had been previously analyzed by the harmonic balance method. In order to examine the influence of the leak magnetic flux on the characteristics of a transformer, we examined the relation of the winding position and the characteristics. As a result, it became clear that the movement point of a transformer can be varied by changing the winding position.
