Abstract

Multilevel inverter is a type of inverter used to generate AC signals with adjustable frequency and better quality. L-C-L passive filter is used to eliminate harmonic distortion in the generated AC signals. Meanwhile, IoT technology is used to remotely monitor and control the speed of the motor through a mobile application. In this thesis, the design of a flying capacitor multilevel inverter is used as an induction motor speed controller with the resulting Total Harmonic Distortion (THD) can be reduced if you add a level to the inverter. Then, L-C-L passive filter is designed to eliminate harmonic distortion in the generated AC signals. Furthermore, the implementation of IoT technology is carried out using Blynk IoT platform. The test results show that the multilevel inverter with L-C-L passive filter successfully generates AC signals with better quality compare without L-C-L passife filter. In addition, IoT technology is successfully implemented and allows users to remotely monitor and control the speed of the motor through a mobile application. Thus, the use of multilevel inverter with L-C-L passive filter and IoT technology can effectively increase the efficiency and control of single-phase induction motor. Keywords: multilevel inverter, L-C-L passive filter, IoT, induction motor, total harmonic distortion.

利用 L-C-L 无源滤波器和物联网技术设计多电平逆变器以监控单相感应电机的速度变化

多电平逆变器是一种逆变器，用于产生频率可调、质量更好的交流信号。L-C-L 无源滤波器用于消除产生的交流信号中的谐波失真。同时，物联网技术被用于通过移动应用程序远程监控电机的速度。在本论文中，飞电容多电平逆变器的设计被用作感应电机速度控制器，如果给逆变器增加一个电平，所产生的总谐波失真（THD）就能降低。然后，设计 L-C-L 无源滤波器来消除产生的交流信号中的谐波失真。此外，还利用 Blynk 物联网平台实现了物联网技术。测试结果表明，带 L-C-L 无源滤波器的多电平逆变器成功地产生了交流信号，与不带 L-C-L 通滤波器的多电平逆变器相比，质量更好。此外，物联网技术的成功应用还允许用户通过移动应用程序远程监控电机的速度。因此，使用带有 L-C-L 无源滤波器的多电平逆变器和物联网技术可有效提高单相感应电机的效率和控制能力。关键词：多电平逆变器；L-C-L 无源滤波器；物联网；感应电机；总谐波失真。
