TRANSFORMER FOR CONTROLLING MAGNETIC CORE

摘要

PURPOSE: A transformer for controlling a magnetic core is provided to control accurately the secondary voltage by using an additional rotary core except for a main core. CONSTITUTION: A transformer for controlling a magnetic core includes a core, a primary core(102), and secondary cores(103,104). The core is formed with an E-shaped fixing core(101) and a rotary core(105). The rotary core(105) is installed at a predetermined position near to the fixing core(101). The primary core(102) is wound around a center part of the E-shaped fixing core. The secondary cores(103,104) are wound around both sides of the center part of the E-shaped fixing core. The rotary core(105) is installed at the center part of the E-shaped fixing core. The intensity of output voltage is controlled by using the rotation of the rotary core.
