Polynomial multi-variable control strategy
for Flux Balancing in Dual Active Bridge Converter


An attractive option for the Dual Active Bridge converter is to integrate the AC coil inside the transformer, using its leakage inductance. However, this complicates the flux balancing process. To address that, a novel model and a multi-variable linear control for power and magnetizing average currents are proposed.
