Abstract

In conventional liquid display using several lamps, several current-balance transformers is used. In this case, not only large installation space is required, but also the cost becomes upsoaring. This invention provides a current-balance transformer which comprises a magnetic core 50 formed by a magnetic element having 2 closed magnetic loops, 1st, 2nd, 3rd 4th coils 41,42,43,44 with the same windings winded on said core 50. The 1st, 2nd windings 41,42 is magnetically combined in opposite polarity with each other, while the 3rd, 4th coils 43,44 is magnetically combined in opposite polarity with each other. The magnetic combination between the coils 41,42 and 43,44 becomes zero. Furthermore, the current-balance transformer is assembled on the two-output type leakage magnetic flux inverter transformer to form a discharge lamp ignition device.
