摘要： A multi-lamp driving circuit includes a power supply, a booster converter including a first winding and a second winding, a plurality of current balance circuits and a plurality of balance converters. The first winding of the booster converter is coupled to the power supply. Each of the current balance circuits includes a plurality of current balance sub-circuits each including a capacitor and a lamp connected in series. One end of each of the current balance sub-circuits is connected to one end of the second winding of the booster converter. A first winding of each of the balance converters is electrically connected between the other end of the second winding of the booster converter and the other end of the current balance sub-circuits of corresponding current balance circuits. Second windings of the balance converters are connected in series.
