Study of push-pull parametric transformer
O. Ichinokura, Kazuki Tajima, Toshimasa Jinzenji · IEEE Transactions on Magnetics · 1992
The parametric transformer has voltage regulation, overload protection, and a kind of filter function for harmonic currents produced by nonlinear loads. The operating characteristics of the push-pull parametric transformer with resistive load are discussed. Furthermore, the authors demonstrate the operation of the push-pull parametric transformer with a thyristor rectifier circuit as an example of a nonlinear load. The authors propose an application of the transformer as a power supply for suppressing higher harmonic currents produced by nonlinear loads such as the thyristor rectifier circuit.>
