Title:
TRANSFORMER FOR HEATER
Document Type and Number:
Japanese Patent JPS55125613
Kind Code:
A
Abstract:

PURPOSE: To reduce a cost and a size, by building a primary coil adjusting inductor in a transformer.

CONSTITUTION: The primary coil 32 and secondary coils 33W35 wound around a frame-shaped ferrite core 31. Since the inductance of the primary coil fluctuates due to the scattering in the properties of the material of the core or in its manufaturing process, auxiliary core plates 38, 39 are interposed between the primary coil 32 and the core 31 so that the inductance of the primary coil is set at an appropriate value depending on a variety of uses. Silicon steel plates in particular are preferable as the auxiliary core plates 38, 39 because silicon steel plates are cheap.
