Abstract
A method for switching between a forward operation and a reverse operation of an isolated bidirectional DC-DC circuit, a controller, a bidirectional converter, and a charging system are provided. The method includes: on receiving a switching signal, controlling a second bridge arm circuit to stop synchronous rectification, and adjusting phases of driving signals of two bridge arm branches in the first bridge arm circuit; in a case that the output current of the second bridge arm circuit reaches a first predetermined current, controlling the first bridge arm circuit to stop operating, and adjusting phases of driving signals of two bridge arm branches in the second bridge arm circuit; and in a case that the output current of the second bridge arm circuit reaches a second predetermined current, controlling the first bridge arm circuit to resume operating and perform synchronous rectification.
