Title:
INVERTER TRANSFORMER
Document Type and Number:
Japanese Patent JP3388401
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize downsizing and cost reduction of an inverter transformer having a closed magnetic circuit structure which turns on a plurality of cold cathode lamps (has nor variation of discharging operation among a plurality of cold cathode lamps connected with a secondary winding).
SOLUTION: A secondary winding 2 are respectively wound around a plurality of separate and independent bar magnetic cores 3 and 3 which are electromagnetically connected with a primary winding 1 at the same characteristic, so that a plurality of secondary windings 2 and 2 which function mutually and independently and are equal electromagnetically and an open magnetic circuit structure can be obtained. In addition, according to the number of lamps, the primary winding 1 is common and only the secondary winding is added without increasing both the primary and secondary windings.
