五电平混合箝位(5L-HC)变换器是一种新提出的适用于高性能中压大功率变换的拓扑结构,无需直接串联开关管。该变换器的关键问题是,每相的两个飞跨电容器电压和直流链路的两个中性点电位需要平衡。提出了一种基于改进相移脉宽调制(PS-PWM)和最优零序电压注入的5L-HC变换器解耦电压平衡方法。通过调整四个PWM信号的宽度,首先平衡中央直流链路电容器和两个飞跨电容器上的电压。其次,研究了中性点电流与输出相电压的关系,并通过零序电压注入来平衡上、下直流侧电容电压。稳态和动态仿真及实验结果证实了该方法的有效性。
Five-level hybrid-clamped (5L-HC) converter is a newly proposed topology which is suitable for high-performance medium-voltage high-power conversions without switches directly connected in series. The critical issue of this converter is that two flying capacitor voltages of each phase and two neutral-point potentials of the dc-link need to be balanced. This paper presents a decoupled voltage balancing method for this 5L-HC converter based on modified phase-shifted pulse width modulation (PS-PWM) and optimal zero-sequence voltage injection. The voltages across the central dc-link capacitor and two flying capacitors are balanced first by adjusting the width of four PWM signals. Second, the relationship between the neutral-point currents and the output phase voltage is studied and the upper and lower dc-link capacitor voltages are balanced by zero-sequence voltage injection. Both steady-state and dynamic-state simulation and experimental results are presented to confirm the validity of this method.
