COMPACT TRANSFORMER, INVERTER CIRCUIT, AND DISCHARGE TUBE LIGHTING CIRCUIT

摘要

PURPOSE:To provide a compact transformer fit for inverter circuit used for compact cold-cathod fluorescent lamp lighting, etc., and the high reliable inverter circuit smaller than conventional one as well as a discharge tube lighting circuit. CONSTITUTION:A transformer is composed of sheet-like or bar like shaped magnetic core comprising single-crystal soft magnetic alloy thin band in the means crystalline particle diameter not exceeding 100nm in thickness not exceeding 30mum shared by crystal particles at least a part thereof or an amorphous soft magnetic alloy thin band in thickness not exceeding 30mum laminated in height not exceeding 3mm as well as at least one primary winding and at least one secondary winding.
