摘要
目前,多电平逆变器在中大功率领域的应用越来越受到重视。本文讨论了最先进的拓扑结构PUC (Packed U Cell)多电平逆变器。这种拓扑的优点是随着电平的增加,交换机的数量减少。因此,与其他现有的拓扑结构(如中点箝位(NPC),飞行电容器(FC),级联h桥(CHB)和混合级联h桥(HCHB))相比,它降低了实现成本和拓扑复杂性。此外,在整个概念中不需要变压器。因此,它避免了庞大的安装。该3- 感应电机馈电与7,15和31级包装U单元(PUC)逆变器拓扑单独。每个电平的定子电流、速度响应和电磁转矩均显示。用转矩脉动%和总谐波失真%对异步电动机的性能进行了分析。整个仿真采用MATLAB/Simulink R2012b版本进行。
Performance analysis and design optimisation of 3-⌀ Packed U Cell inverter for industrial drive applications
Nowadays, the importance for multilevel inverters is getting more and more in the field of medium and high power applications. This paper discusses Packed U Cell (PUC) multilevel inverter which is the most advanced topology. The figure of merit of this topology is reduction in the number of switches as level increases. Hence, it reduces the cost implementation besides topology complexity compared to other existing topologies such as neutral-point clamping (NPC), flying capacitor (FC), cascaded H-bridge (CHB) and hybrid cascaded H-bridge (HCHB). Furthermore, there is no need of transformers in this whole concept. Hence, it avoids the bulky installations. The 3-⌀ induction motor is fed with 7, 15 and 31 levels Packed U Cell (PUC) inverter topologies individually. The stator current, speed response and electromagnetic torque is shown for each level. The performance of induction motor is analysed in terms of % torque ripples and % total harmonic distortion (%THD). The whole simulations are carried out by using MATLAB/Simulink version R2012b.
