Multi-Condition PSO-FOPI Current-Sharing Control for Parallel LLC Resonant Converters under Parameter Deviations

Parallel LLC resonant converters are suitable for low-voltage and high-current applications. However, deviations in the resonant inductor, resonant capacitor, and magnetizing inductor cause gain differences among phases, resulting in output-current imbalance. To address the difficulty of achieving satisfactory multi-co...
