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.
