1. A DC-DC converter, comprising:
a transformer;
a first switching circuit and a second switching circuit, each coupled to one of two sides of the transformer, respectively, and each comprising at least two switches;
a first current detection module coupled to a first side of the transformer and configured to detect a current at the first side;
a first conversion module coupled to an output of the first current detection module and configured to convert a signal of the current detected by the first current detection module to a voltage signal;
a first comparison module coupled to an output of the first conversion module and configured to compare the voltage signal from the first conversion module with a reference voltage signal, and generate a first modulation signal based on a result of the comparison; and
a first controller coupled to an output of the first comparison module and configured to generate a first control signal for at least one switch in the second switching circuit, the first control signal being based on the first modulation signal and a drive signal of at least one switch in the first switching circuit.
