Claim 2:
3. The converter according to claim 1, wherein the drive signal for the upper bridge switch and the drive signal for the lower bridge switch of the half-bridge circuit are generated according to the voltage loop output value of the converter, the instantaneous voltage value of the AC input at the AC input end, and the instantaneous current value of the current signal on the primary side of the transformer, comprising:
a peak current given value of the transformer obtained by multiplying the voltage loop output value with an absolute value of the instantaneous voltage value of the AC input at the AC input end; and
the drive signal for the upper bridge switch and the drive signal for the lower bridge switch of the half-bridge circuit, which are generated 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, and are configured to change the current signal on the primary side of the transformer according to the regularity of the AC voltage signal input at the AC input end.
