“…After analyzing 27 possible switching state combinations related to three-to-three-phase MC, it can be noted that 6 of them correspond to rotating voltage space vectors. If the MC is supplied by balanced input voltage (11), the rotating voltage space vectors have the same modules, equal to the amplitude of the input voltage and have the same angular speed on the complex plane. Three of these vectors rotate in counter clockwise direction and are named CCW vectors, and rest of them rotate in clockwise direction and are named as CW vectors (Table 1).…”

“…The mentioned conclusions were drawn for the case when the voltages supplying the MC are the sinusoidal balanced voltage (11), and the CMV for three-to-n-phase MC is specified as (12). The U i and ω i in the relation (11) are the amplitude and angular frequency, respectively. Taking into account the conclusions drawn from the [20], the proposed modulation strategy is addressed to the topology for which the number of output phases is an integer multiple of input phases number.…”

“…In the software solution, to achieve the CMV elimination, a modification of the modulation methods is applied. A majority of these methods are focused on modification of classic space vector modulation (SVM), applying active and zero voltage space vectors to synthesize output voltage in the MC [8][9][10][11][12][13][14]. The zero vectors resulting in the highest value of CMV are replaced by using combinations of active vectors or rotating space vectors, that are related to an increase in the number of switch commutations.…”

In the last several years, thanks to the development and continuous improvement of semiconductor switching elements, and the simultaneous increase in interest in multi-phase drives, the investigation into constructing multi-phase converters has been growing. The matrix converter (MC) is considered to be one of the contenders for use in the multi-phase drive. In the context of using MC in the drive, it is expected to eliminate the common mode voltage (CMV). Another important problem is the ability to correct the input displacement angle to ensure the operation of the MC with unity input power factor. The purpose of the article is to present an MC modulation strategy that implements both CMV elimination and input displacement angle adjustment. Analytical and simulation analyses of the strategy, in application to three-to-multi-phase MC is presented. The suggested modulation strategy in applying to three-to-multi-phase MC is implemented in ATP-EMTP (Alternative Transients Program-ElectroMagnetic Transients Program) software. Simulation results are provided for a three-to-three-phase three-to-six-phase and three-to-nine-phase MC. The proposed modulation strategy is validated using an experimental approach.

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.

SummaryThis paper targets to minimize the peak common mode voltage (CMV) in ultra sparse matrix converters (USMC) by applying new zero vectors for the space vector modulation technique (SVM). Conventional zero vectors in the SVM raise the peak CMV by 42.23%. An increased magnitude of CMV is associated with the occurrence of leakage current, hence resulting in insulation degradation. So, the reduction of peak CMV is necessary for USMC. The proposed method offers suitable switching arrangements using auxiliary shoot through (AST) switches to minimize the peak‐to‐peak CMV. This proposed method holds the advantages of the conventional method, like a wide range of modulation index and zero current switching at the rectifier side, and also reduces the CMV problem. This paper also provides a comparative analysis of the existing reported methods and the proposed method. The effectiveness of the proposed method is validated through both simulation and experimental results.
