Outline
To solve the device voltage endurance, voltage change rate and series-parallel problems of traditional two-level dual active bridge (DAB) converters under high voltage and high power, the active neutral point clamped (ANPC) topology is integrated into the DAB converter to form a multilevel DC-DC converter. This converter offers four control degrees of freedom, overcoming the shortcomings of traditional topologies and the limitations of modulation methods. It is suitable for medium to high voltage applications with a wide voltage transfer range. To enhance the efficiency of the multilevel converter, a minimal peak current multi-phase shift (MPS) modulation strategy with four degrees of freedom is proposed. Initially, the operational principles of the converter are analyzed, and the peak inductor current for each operational mode is derived. Subsequently, a power transfer model is established, leading to a multi-degree-of-freedom analytical solution. The minimum current stress is optimized using the KKT (Karush-Kuhn-Tucker) algorithm. Finally, an experimental platform is constructed for testing, comparing the optimization effects of different modulation strategies under various operating conditions to validate the effectiveness of the proposed strategy.
