摘要:在分析了基于输入电压的4步换流和2步换流策略的基础上,提出了改进的2步换流方法。该方法不需要检测负载电流方向,消除了测量误差带来的缺陷,同时,实现了换流时间的最小化,增强了换流的可靠性,改善了输入、输出波形质量。通过仿真分析,从换流开关脉冲比较及输入、输出波形的改善方面验证了改进的2步换流实现方法的正确性。
After the analysis of the input voltage-based four-step and two-step commutation strategies,this paper proposed an improved implement method of two-step commutation.With this method,it is not necessary to detect the direction of load current and the limitation by measurement error was decreased.Meanwhile,the commutation time was minimized.Therefore,the reliability of commutation was increased and the quality of input and output waveforms was improved.Finally,the simulation analysis was carried out.The correctness of the proposed method was verified from two aspects,which were the comparison of switching pulse and the quality of input and output waveform.
