  • Publication number: 20220416672
    Abstract: An isolated bidirectional converter and a method for controlling the same are provided. A primary winding or a secondary winding of a transformer module in the isolated bidirectional converter is connected in parallel with a first branch includes a first inductor and a first current sensor that arc connected in series, A current flowing through the first inductor is acquired by the first current sensor, and is proportional to a current flowing through a magnetizing inductor of the winding. Therefore, the current is controlled by modifying a duty cycle of a switch transistor on a bridge arm in the circuit, so that a. direct current component of a current flowing through the winding is modified indirectly, thereby avoiding magnetic bias on the magnetizing to inductor of the transformer module, and preventing the transformer module from being saturated.
