摘　　要：矩阵式变换器是风力发电系统中的一种新型电力变换器。在研究矩阵式变换器的双电压控制策略的基础上,以方便、可靠地实现控制策略为目标,提出了双电压控制策略的改进方法。改进的双电压控制策略简化了开关组合,并推导出统一的占空比计算公式,从而减少了系统计算量,方便了编程实现,提高了程序的效率和实时性。在MATLAB/Simulink仿真研究的基础上,研制了矩阵式变换器样机进行实验研究,仿真及实验结果验证了改进后控制策略的可行性和优越性。Matrix converter is a new type of power converter in the wind energy conversion system. Aiming at realizing the control strategy easily and reliably, an improved voltage control strategy is proposed based on the research on double line-to-line voltage control strategy of matrix converter. The improved double line-to-line voltage control strategy simplifies switching combinations and derives a unified formula to calculate the duty ratio. The improved strategy can steadily reduce computational load, facilitate programming and enhance the efficiency and real-time performance of the program. The matrix converter is modeled with MATLAB/Simulink and an experimental prototype is also built up. The simulation and experimental results verify the feasibility and validity of the improved double line-to-line voltage control strategy .
