  • Patent number: 12170442
    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.
