Claim 1:
2. The converter according to claim 1, wherein the preset time is determined according to a difference between a positive peak current value and a negative peak current value on the primary side of the transformer, the instantaneous voltage value of the DC output by the converter, and parameters of the excitation inductance of the transformer, comprising:
the preset time TLG is determined according to the following formula:, T
