摘要

在高压大功率场景下，传统两电平双有源桥DAB（dual active bridge）变换器存在器件耐压不足、du/dt大以及模块串并联数量多等问题。基于此，将一种有源中点钳位ANPC（active neutral point clamped）拓扑引入DAB变换器中，构成一种器件混合型多电平DC-DC变换器。该变换器能够提供4个控制自由度，克服了传统拓扑的不足及调制方式自由度的局限性，适用于电压传输比变化范围宽的中高压场合。为提高变换器的效率，提出了一种最小化电感电流峰值多移相MPS（multi-phase shift）调制策略。分析了变换器的工作原理，推导出各个工作模式下的电感电流峰值，然后建立传输功率模型，求得其多自由度解析解，并基于KKT（Karush-Kuhn-Tucker）算法进行了最小电流应力优化。最后，搭建实验平台进行测试，对比不同工况下不同调制策略的优化效果，验证策略的有效性。

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.
