| Abstract |
This paper presents an optimization procedure based on a genetic algorithm for the dual-loop control scheme employing type-III controllers for a 6-phase interleaved converter. The optimized type-III current- and voltage-controllers are derived from four different objective functions that represent for their control costs. A comparative step response performance of these type-III controllers using the optimization objective functions is carried out to select a final optimized design to be compared with `k-factor' approach design. To this end, experimental results with two testing scenarios are provided for the theory validation. In this regard, 40kW static testing confirms the validity of the proposed dual-loop control scheme. Besides, with 50\% step load change at maximum 12kW, dynamic testing can verify the advantages of optimized controllers over the classical `k-factor' counterpart. |
