The conventional topology of direct single‐to‐single‐phase matrix converter (SSMC) is widely adopted in industrial and power system‐related applications owing to its desired features. Current control methods in the literature either limit the voltage transfer ratio (VTR) or prohibit their utilization to drive inductive (RL) loads. In this study, we propose a novel control method that overcomes these limitations by enabling the SSMC to achieve relatively high VTRs while driving RL loads with negligible output voltage spikes and without current commutation problems. Further, the proposed control method improves the overall performance by reducing output voltage and source input current total harmonic distortion (THD) and offering soft‐switching at the commutation instances. The rigidity of the proposed control method over the counterpart methods in the literature is verified through simulation and experimental case studies over a wide range of synthesized output frequencies and modulation indexes. A 530‐W laboratory prototype is built for the experimental study. Results demonstrated the ability of the proposed method in enabling the SSMC to drive an RL load without current commutation issues and with mitigated output voltage spikes while achieving relatively high VTRs and suppressing the output voltage and source input current THD.

“…There are some studies about matrix converter-fed singlephase induction motor in [10][11][12][13][14]. There are also various studies to be found in the literature on single-phase matrix converters [15][16][17][18][19][20]. Nevertheless, there is a low-efficiency disadvantage in the mentioned system.…”

A direct matrix converter structure and a two-phase permanent magnet synchronous motor (PMSM) are designed to increase the system efficiency in low-power motor drive applications. The drive system with two-phase PMSM has been proposed instead of the single-phase squirrel cage induction motor, which has low efficiency. A constant AC single-phase power supply can be directly converted to frequency and amplitude-adjustable two-phase power supply by the proposed converter structure. However, the proposed converter cannot generate the sufficient voltage level for a standard commercial motor. For this reason, a new two-phase PMSM is designed to adapt the converter output voltage amplitude with the motor-rated voltage by using Infolytica/MotorSolve software. A novel switching algorithm has been developed and analysed to show output voltagecurrent waveforms of the converter with their harmonic spectrum. In addition, the converter is designed compactly to be mounted to the terminal box of the designed motor. Experimental results have been obtained for speed control of the motor by using vector control at different reference speeds.

In this study, a direct ac-ac matrix converter is proposed to control a single-phase induction motor having main and auxiliary stator windings. This type of motors is widely used in low-power industrial machines, home appliances and many applications where single-phase grid is used. However, they require almost 90°phase shift between the windings to obtain self-starting and high starting torque by using starting capacitor, centrifuge switch and auxiliary winding. These requirements can be met by the proposed converter which generates two-phase output voltages with 90°phase shift and adjustable amplitude/frequency. The proposed converter can eliminate some disadvantages of inverter-based drive systems which require a bulky dc-link capacitor and a rectifier circuit. Also, regenerative operation, which is an important feature for electric motors, can be provided with the proposed converter structure. The converter has been tested with an R-L load and a standard single-phase induction motor with two-phase winding. Simulation and experimental results of the output voltages and load currents for the proposed drive system have been given for various output conditions. The performance of the motor has been also demonstrated for various speeds.
