摘要:
针对三电平逆变器直流电压失衡问题,首先分析了T 字型拓扑三相四线制三电平电路的输出电压与触发脉冲间的关系,并给出基于DSP+FPGA 主从结构控制器的脉冲实现方法;分析了逆变器换流过程中能量的流向及直流电压失衡的根本原因,并对其脉冲产生方法进行改进;最后将分析结果在三相四线APF 平台上进行了验证。
Abstract:
To solve the imbalance problem of DC voltage in three-level inverter, the relationship between output waveforms of a three-phase four-wire system and its trigger pulse was analyzed, and a pulse realization method based on DSP+FPGA controller was given. This paper analyzed the flow of energy during the converting process and the root causes of DC voltage imbalance, and improved the method of pulse generation. Finally, the analysis results were verified on a three-phase four-wire APF platform.
