1. A power converter, comprises:
a voltage control unit configured to generate a first current command;
a current control unit; and
a hysteresis control unit coupling the voltage control unit with the current control unit, and configured to:
in a first mode, when a detection current reaches a first threshold value, decouple the voltage control unit and the current control unit, and generate a second current command to transmit to the current control unit; and
when the first current command reaches a second threshold value, couple the voltage control unit with the current control unit, and transmit the first current command generated by the voltage control unit to the current control unit for switching to a second mode from the first mode of the power converter;
wherein the current control unit is configured to output a mode control signal according to the first current command and the second current command.
