ABSTRACT Modulation algorithms of indirect matrix converters (IMCs) are complicated and need powerful processors, such as DSP along with FPGA or CPLD for implementation. Using any extra hardware increases the cost and complexity and also reduces the reliability of the system. In this paper, a new realization for the space vector modulation (SVM) of the IMC is proposed so that it can be implemented by using a single low-cost 32-bit ARM-based microcontroller chip without any additional hardware. Therefore, due to the elimination of the extra hardware in the proposed method, the compact design in the control part of the system is provided so the reliability of the system is increased. Moreover, the cost of the system can be significantly reduced in low-power applications. This realization is based on using the timer-counter modules and the interrupt routine of the microcontroller. Therefore, the CPU burden is also minimized and the microcontroller can perform other tasks such as calculation of complex control algorithms. This feature can also be valuable in some applications. The experimental results of an IMC connected to the RL and a motor load demonstrate the validity of the proposed method.

一种用于间接矩阵转换器的基于 SVM 算法的新型低成本微控制器实现

摘要 间接矩阵转换器 (IMC) 的调制算法很复杂，需要强大的处理器，如 DSP 以及 FPGA 或 CPLD 来实现。使用任何额外的硬件都会增加成本和复杂性，同时也会降低系统的可靠性。在本文中，提出了一种新的 IMC 空间矢量调制 (SVM) 实现方法，它可以通过使用单个低成本 32 位基于 ARM 的微控制器芯片来实现，而无需任何额外的硬件。因此，由于所提出的方法中去除了额外的硬件，使得系统控制部分的设计更加紧凑，从而提高了系统的可靠性。此外，在低功耗应用中可以显着降低系统成本。该实现基于使用定时器-计数器模块和微控制器的中断例程。因此，CPU 负担也被最小化，并且微控制器可以执行其他任务，例如复杂控制算法的计算。此功能在某些应用程序中也很有价值。连接到 RL 和电机负载的 IMC 的实验结果证明了所提出方法的有效性。
