| 摘 要： | 三电平逆变器拓扑结构简单、所用器件较少且每个功率管所承受的电压应力小，适用于高电压、大容量的场合.相比于传统两电平逆变器，三电平逆变器输出电平的数量从2变成3，输出的电压电流谐波含量低，波形正弦度更好.本文提出内置式永磁同步电机模型预测电流控制算法，以提高控制系统电流动态响应速度，并针对该算法在控制系统中产生的时间延迟，引入二阶延迟补偿策略.对以上内容建立系统仿真模型，仿真结果表明：三电平逆变器相比两电平逆变器输出电流波形谐波含量更小、电机的动态及稳态性能更好.

| Abstract: | The three-level inverter is suitable for high voltage and large capacity occasions for its advantages such as simple topology,less devices,and small voltage stress on each power transistor.Compared with the legacy two-level inverter,three-level inverter has more output levels,lower voltage and current harmonic content,and better sine waveform.A Model Predictive Current Control (MPCC) scheme is proposed for Interior Permanent Magnet Synchronous Motor (IPMSM) to improve its current dynamic response speed,and a second-order delay compensation strategy is presented to solve the time delay in control system.Validity of the proposed MPCC scheme is confirmed by simulation.The simulation results showed that the IPMSM-MPCC driven by three-level inverter has smaller harmonic content in output current waveform,better dynamic and steady-state performance,compared with that driven by two-level inverter. |
