摘要：The present application relates to a drive circuit in an inverter circuit (T1, T2, T3).Said inverter circuit comprises a switching circuit (4) connected to a power source (1); aplurality of primary coils (T1-1, T2-1, T3-1) of a plurality of inverter transformersconnected to said switching circuit; and a plurality of discharge tubes (FL1, FL2, FL3)connected to a plurality of secondary coils (T1-2, T2-2, T3-2) of said inverter transformers.The inverter circuit uses a plurality of balance transformers (CT1, CT2, CT3) to equalizeeach currents of the plurality of discharge tubes. Furthermore, the drive circuit comprisesat least two of transformer apparatuses each including an inverter transformer having aprimary coil and a secondary coil and a balance transformer having a primary coil and asecondary coil, wherein in each of the transformer apparatus, the inverter transformerand the balance transformer are integrally formed by sharing a part of their core portion.
