A new bridge-connected magnetic circuit using amorphous magnetic core and its applications

This paper is a description of the operating principle and the circuit configuration of a new bridge-connected magnetic circuit proposed by the authors. This magnetic circuit is constructed by a toroidal amorphous magnetic core with high permeability and a usual magnetic core with low permeability and has a number of excellent characteristics in the operation. Using this circuit the authors made various interesting devices used as the instrument and the control.
