Summary A matrix converter (MC) is a topology for ac‐ac power conversion that has been widely investigated and compared with conventional ac‐dc‐ac topologies because of its attractive features. The MC is formed of controlled active devices and does not include any sizeable passive components. The converter can be used to directly control single/three/multiphase loads. MCs are highly effective in controlling the power factor and providing sinusoidal input and output currents. This paper provides a comprehensive state of the art review of the MC and discusses the main topology variations including single‐phase conventional and isolated MCs, three‐phase direct and indirect MCs, impedance source (Z‐source) MCs, multiphase MCs, and multilevel MCs (MMCs). The aim of this research article is to provide a one‐stop information on single/three/multiphase matrix, Z‐source matrix, and multilevel MCs for potential readers, researchers, and practicing engineers.

“…A direct AC-to-AC conversion of power without the need for DC-energy storage is possible with MCs. They have lately received a lot of attention as an alternative to the traditional rectifier inverter [11,12]. Many benefits can be obtained from MCs, including sinusoidal input-and output-current waveforms, high power density, unity-input-power factor and four-quadrant operation [13,14].…”

A Simple Commutation Method and a Cost-Effective Clamping Circuit for Three-to-Five-Phase Indirect-Matrix Converters

This article presents and analyzes a three-to-five-phase indirect matrix converter (IMC) structure for directly supplying a five-phase static R–L load from a three-phase supply. The IMC topology offers a lower number of switches, a simple commutation procedure and a cost-effective clamping circuit in comparison to the direct matrix converter (DMC). A simple clamping circuit with one ultrafast diode and one small capacitor is proposed to protect the switches of the IMC from overvoltage. The issues of powering up the IMC with the simple clamping circuit is discussed in detail. The instructions for the safe start-up of the IMC with the proposed clamping circuit is introduced based on the simulated and the measured analyses. Moreover, a carrier-based pulse-width-modulation (CBPWM) method is also presented in order to control the switches of the IMC. The presented CBPWM method creates PWM pulses for both the inverter and the rectifier legs by using only one symmetric and triangular carrier signal. Finally, experimental and simulation testing with a five-phase R–L load demonstrate the viability and the efficiency of the introduced CBPWM algorithm for the suggested IMC.

“…In addition, improving the control strategy algorithm by software method is another conventional way for reducing the inverter output common-mode voltage. Sinusoidal pulse width modulation (PWM) is one of the most utilized conventional modulation techniques for inverters control and commonmode voltage reduction [13], [14]. Although the improved PWM control strategy does not require additional investment, the design of the PWM model and the implementation of such methods are more complex [15].…”

In this paper, a novel model predictive control (MPC) via a double vector optimized selection method is proposed. The main idea of this method is for decreasing the high common-mode voltage of two-level inverter under balance situation, improve the tracking performance of the output current and decrease the high output current harmonic distortion rate. To solve the problem of increasing the value of total harmonic distortion (THD) due to the reduction of the available voltage vector, this method controls two voltage vectors in each sampling period for getting a better tracking performance of the output current. Simultaneously, compared with the adding virtual vector MPC method, which results in excessive switching losses, the proposed method defining the selection range of the second voltage vector. Only two voltage vectors adjacent to the first voltage vector can be selected so that the switching frequency can be greatly reduced. An experimental control platform based on Simulink-Real-Time system is presented for the further verification of the effectiveness of the proposed control method. The simulation and experimental results showed that the proposed method could effectively reduce the output common-mode voltage of the inverter. Simultaneously, the THD value and the switching loss are greatly reduced.INDEX TERMS Model predictive control, common-mode voltage, double vector controlling, three-phase two level inverter.
