“…Assuming that the initial value of the cost function is infinite, when the temporary variable j changes from 0 to 7, the states of the MOSFETs will be determined. First, the voltage vector can be obtained according to Equation (13). Then, the predicted current in the d-q axis can be calculated from Equations (22) and 23, respectively.…”

In this study, a current model predictive controller (MPC) is designed for a permanent magnet synchronous motor (PMSM) where the speed of the motor can be regulated precisely. First, the mathematical model, the specifications, and the drive topology of the PMSM are introduced, followed by an elaboration of the design of the MPC. The MPC is then used to predict the current in a discrete-time calculation. The phase current at the next sampling step can be estimated to compensate the current errors, thereby modifying the three-phase currents of the motor. Next, Simulink modeling of the MPC algorithm is given, with three-phase current waveforms compared when the motor is operated under the designed MPC and a traditional vector control for PMSM. Finally, the speed responses are measured when the motor is controlled by traditional control methods and the MPC approach under varied speed references and loads. In comparison with traditional controllers, both the simulation and the experimental results suggest that the MPC for the PMSM can improve the speed-tracking performance of the motor and that this motor has a fast speed response and small steady-state errors under the rated load.

“…While the GaN-based VFDs (using a standard three-phase two-level voltage source inverter) are commercially available in the industry, a matrix converter is becoming a popular alternative for next-generation motor drive systems [3][4][5][6][7]. Figure 1 shows the typical two-level voltage source inverter and the matrix converter block diagram for the VFDs.…”

Gallium nitride (GaN) devices have been widely adopted to achieve high efficiency and high power density as alternative solutions to silicon devices. When the GaN power devices are used for variable frequency drive (VFD) systems, the high dv/dt pulses at the motor terminal, which induce shaft voltage and common mode current, should be carefully considered to ensure system reliability. Although the high dv/dt issues can be mitigated with a dv/dt filter method, it leads to performance degradation depending on cable length. Meanwhile, a matrix converter also becomes a next-generation power converter for the VFDs which has a regeneration capability and unity power factor. Thus, this paper discusses the GaN-based matrix converter for the VFD as a study case considering the motor terminal voltage quality and the common mode current. Also, a sine wave filter is adopted to cope with the terminal voltage quality irrespective of cable length. The optimized design procedure of the sine filter considers practical issues. Experimental results are presented to suggest a suitable solution for the GaN-based VFDs in accordance with the cable length.

“…Also, the modulation techniques for the matrix converter are mainly investigated based on high switching frequency techniques. [4][5][6] In Klumpner et al 7 and Huber and Borojevic, 8 it is observed that at low switching frequencies, the VSCs are more efficient than the matrix converter, whereas at higher frequencies, the reverse is true. The various modulation and control techniques used for the matrix converter are shown in Figure 1.…”

“…The various modulation and control techniques used for the matrix converter are shown in Figure 1. [3][4][5][6][7][8] At the beginning of the advent of the matrix converter, the transfer function-based method, also known as Venturini method, is mostly used. 10,11 In this method, the desired output voltage is obtained by multiplying the input voltage and the converter transfer matrix.…”

Summary This paper presents a low switching frequency–based pulse width modulation technique for a 3 × 3 indirect matrix converter. The nontriplen lower‐order harmonics are considered for minimization using differential evolution–based metaheuristic technique. The mathematical equations are formulated while considering minimization of nontriplet lower‐order harmonics along with control of fundamental voltage. An objective function is constructed by considering all the constraints on the feasible region and then it is minimized by using differential evolution technique. It is observed that the solution in the entire modulation range exists along with multiple solutions. Various cases of switching angles are considered, and solution trajectories are reported in practically feasible range. This type of modulation and control scheme is extremely useful in high power applications such as unified power flow controller as it minimizes the switching losses in the converter. The theoretical findings are verified by simulation and hardware results.
