Some experiments and considerations on behavior of the power converter with bridge-connected reactor circuit

Recently, a new type of a parametrically excited power converter which is made by two C-cores rotated at 90° was proposed and called as Paraformer [1]. The novel characteristic of this device has been remarked as one of the important phenomena which permit to expand the new region of nonlinear magnetics [2], although the operation principles are not yet clearly understood. It is concluded from the present work that the performance characteristics of the bridge-core circuit which we designed are completely agreed with that of the Paraformer, and a novel characteristic of the Paraformer is generated by the bridge circuit. By using the symmetrical or the asymmetrical bridge-core circuit, it is possible to make not only a practical high efficient and high sensitive voltage regulator but also a power converter which can change the output frequency. Furthermore, a large capacity power converter can be achieved by constructing a bridge circuit with 3-5 separate reactors.
