ABSTRACT:
A discharge tube drive circuit for driving a plurality of discharge tubes is proposed with reduced number of parts and in a down-sized form. A first balance transformer is provided in a first drive circuit block, and a plurality of primary coils of a plurality of drive transformers in the first drive circuit block and a secondary coil of the first balance transformer are connected in series. A second balance transformer is provided in a second drive circuit block, and a plurality of primary coils of a plurality of drive transformers in the second drive circuit block and a secondary coil of the second balance transformer are connected in series. Further, a primary coil of the balance transformer and a primary coil of the second balance transformer are connected in series to configure the discharge tube drive circuit of the present invention.
