摘要 电流源变换器直流链电感电流纹波是系统运行的重要性能指标之一。实际应用中可通过提高开关频率或增大电感值减小直流链纹波。然而,提高开关频率会引起系统开关损耗增加,增大电感值会导致系统体积增大、成本提高。为了解决上述问题,首先分析传统方案电流纹波的时域表达式,揭示传统方案存在的问题,然后提出一种基于优化开关矢量序列的新型控制方案,其效果是:在不增加开关频率和硬件的情况下,有效减小了直流链电流纹波。搭建TMS320F28335DSP+XC3S400FPGA数字控制硬件实验平台,对提出方案进行实验研究,实验结果验证了提出方案的有效性。 DC-link current ripple is one of the important factors for operating the current source converter. In practice, the DC-link current ripple can be reduced by increasing the switching frequency or inductor. However, it may result in the higher switching losses, larger size or higher cost. In order to deal with this problem, the inherent limitation of the conventional solution is discussed by deriving the time-domain equation of the DC-link current. And then, a new control strategy based on an optimized switching vector sequence is proposed. The DC-link ripple can be effectively reduced with no need of increasing the switching frequency or any hardware. Finally, the proposed method was implemented on the TMS320F28335DSP+XC3400FPGA digital control hardware platform. The experimental results verify the effectiveness of the proposed strategy.
