中文摘要

有源中点钳位(ANPC)变换器可分解为低频单元(LFC)和高频单元(HFC),其基频运行模式正受到关注。然而,在保持输出电流快速控制的同时,平衡直流母线电压和三个飞跨电容电压始终是一项挑战。

English Abstract

Active-neutral-point-clamped (ANPC) converters can be decomposed into a low-frequency cell (LFC) and a high-frequency cell (HFC), and fundamental-frequency operation of the LFC is becoming popular. However, balancing the dc-link voltage and three flying capacitor voltages while maintaining very fast control of the output current is always a challenging task, especially when the flying capacitor is...
