Abstract
A micro parametric transformer previously proposed by authors has various desirable features, including voltage regulation, overload protection, and noise rejection. This paper analyzes the performance of the transformer and validates the magnetic circuit model of the transformer used for the analysis. The performance characteristics of the transformer are analyzed by solving the nonlinear differential equation obtained from the parametric oscillation circuit. The equation is solved by the harmonic balance method. The calculated characteristics of the transformer agreed approximately with the experimental ones. The validity of the proposed magnetic circuit model was confirmed.
