Abstract

PURPOSE:To make it possible to adjust the variation in inductance of the primary coil of a heater transformer without using a variable inductor by screwing a screw core equipped with an auxiliary coil connected to the primary coil on a magnetic core equipped with at least one primary coil and one secondary coil. CONSTITUTION:A rectangular ferrite core 31 is equipped with a primary coil 32 and secondary coils 33-35, the outputs of the secondary coils being used as a power source for a heater transformer. In this constitution, the ferrite core generally has the variation in the manufacturing process or material characteristic, so that the primary coil has the variation in inductance. Such variation is adjusted as follows: made on the part of the core 31 adjacent to the primary coil 32 is a female screw 39, in which a screw core 300 equipped with an auxiliary coil 36 is screwed, the coils 36 and 32 being connected in series. Thus, the variation in inductance can be adjusted without installing a variable inductor separately.
