摘要
在中高电压、大容量变流领域,三电平变流器以输出功率大、器件电压应力低等特点逐渐进入了实用阶段。但由于此类变流器中功率器件数量较多,采取传统三电平空间矢量脉宽调制(SVPWM)算法运算量庞大,算法实现困难,对硬件资源要求高。为此针对传统三电平变流器算法进行了改进,大大简化了算法描述。在控制器数字实现过程中,不仅节省了数字处理器的硬件资源,且明显提高了算法的可靠性。相关的模拟实验结果充分证明了所设计算法的可行性和优越性,为后续的研究工作奠定了基础。
In the medium and high voltage,large capacity variable flow field,the three-level converter with high output power,low voltage stress characteristics of the device has gradually entered the practical stage.However,due to the large number of power devices, the calculation of traditional three-level space vector pulse width modulation （SV- PWM） algorithm is very heavy, and the algorithm is difficult to achieve.Aiming at improving the traditional three-level inverter algorithm,the algorithm description is greatly simplified.In the digital implementation of the controller,the hardware resources of the digital processor are saved, and the reliability of the algorithm is obviously improved.The related simulation results verify the feasibility and superiority of the proposed algorithm, which lays the foundation for the following research work.
