<p>A discharge tube drive circuit for driving a plurality of discharge tubes (L1-L4) is proposed. A first balance transformer (CT1) is provided in a first drive circuit block (A), and a plurality of primary coils (T1-1,T2-1) of a plurality of drive transformers (T 1 ,T 2 ) in the first drive circuit block (A) and a secondary coil (CT1-2) of the first balance transformer (CT1) are connected in series. A second balance transformer (CT2) is provided in a second drive circuit block (B), and a plurality of primary coils (T3-1,T4-1) of a plurality of drive transformers (T 3 ,T 4 ) in the second drive circuit block (B) and a secondary coil (CT2-2) of the second balance transformer (CT2) are connected in series. Further, a primary coil (CT1-1) of the first balance transformer (CT1) and a primary coil (CT2-1) of the second balance transformer (CT2) are connected in series to configure the discharge tube drive circuit of the present invention.</p> |
