The present invention provides a lamp driving circuit. When it is used to drive a number of lamps arranged in a hybrid serial-parallel configuration, the lamp driving circuit eliminates the parasitic current in series branch circuits by using an inverse transformer, which makes the current passing each of the lamps in each of the series branch circuits consistent and consequently eliminates the imbalance of each of the lamps.
