Claim 3:
4. The converter according to claim 3, wherein generating the drive signal for the upper bridge switch and the drive signal for the lower bridge switch of the half-bridge circuit according to the peak current given value of the transformer and the instantaneous current value of the current signal on the primary side of the transformer comprises:
the peak current given value of the transformer is compared with the instantaneous current value of the current signal on the primary side of the transformer;
the high-level drive signal is output to the upper bridge switch to drive the upper bridge switch to be switched on, if the peak current given value of the transformer is greater than the instantaneous current value of the current signal on the primary side of the transformer, wherein the drive signal for the upper bridge switch and the drive signal for the lower bridge switch are complementary; and
the low-level drive signal is output to the upper bridge switch to drive the upper bridge switch to be switched off, if the peak current given value of the transformer is less than the instantaneous current value of the current signal on the primary side of the transformer, wherein the drive signal for the upper bridge switch and the drive signal for the lower bridge switch are complementary.
