中文摘要

NPC-DAB变换器在中高压应用中备受关注。本文针对其稳态效率、直流偏置消除、动态响应、恒功率负载稳定性及中点电压平衡(MVB)等核心挑战,提出了一种高性能边界控制策略,通过推导多轨迹自然开关面,实现了变换器的高效与快速动态控制。

English Abstract

As the preferred topology for medium or high voltage applications, neutral-point-clamped dual-active-bridge (NPC-DAB) converters have recently received widespread attention. The main objectives of NPC-DAB converters include high steady-state efficiency, dc-bias elimination, fast dynamic characteristics, constant-power-load stability, and midpoint voltage balance (MVB). NPC-DAB converters may also ...
