Abstract: Disclosed are a multi-port magnetic network energy router and a control method. A magnetic network energy router includes a dual magnetic plate crimped N-winding transformer containing distributed magnetic core columns, and N full-bridge converters. The control method includes: S1. calculating equivalent connection inductance between different converters; S2. calculating steady-state control phase shift angles on the basis of reference powers of all converters; S3. calculating a power decoupling control matrix; S4. calculating control phase shift angle micro-increments of second to Nth converters by the power closed-loop control; and S5. controlling the converters to output square-wave voltages of 50% duty with different phase shift angles, and realizing given-power control. According to the present disclosure, multiple full-bridge converters can be effectively integrated and power density of the system can be improved, and equivalent large leakage inductance can be magnetically integrated at each converter port to realize given high-power energy routing at each port.
