“…Another realization of modulation method with the use of the rotating voltage space vector only, is presented by the authors of [29,30]. To find the duty cycles of the switches, the authors of [29] use the transformation of rotating voltage space vectors into components in a perpendicular system dq, rotating at an angular velocity corresponding to the output voltage angular frequency. This scheme adopts five out of the total six rotating vectors for operation of the MC.…”

“…In practical implementation, commutation and real parameters of the switches have to be taken into consideration. Several commutation strategies are discussed in the literature [29,[31][32][33][34]. The four-step commutation strategy is commonly used.…”

“…The four-step commutation strategy is commonly used. In [29] and [32], authors prove that considering the commutation strategy creates space vectors which do not provide the elimination of the CMV. Then, the authors present a modified four-step commutation that inserts delay times in the commutation sequence, which makes it possible to achieve the zero CMV in the practical implementation.…”

A multiphase matrix converter (MC) is a direct AC/AC converter with n-phase input and m-phase output that is required to supply multiphase systems. To synthesize the controllable sinusoidal output voltage and input current with controllable displacement angle, the pulse width modulation (PWM) is implemented. On account of the PWM usage, there is common mode voltage (CMV), which is detrimental and causes lots of failures. This paper investigates the CMV elimination in the three-to-nine-phase MC. The carrier-based space vector modulation (SVM) with Venturini modulation functions is used. The elimination of the CMV is realized by applying rotating voltage space vectors only. The simulation results presented in this study show that the CMV is entirely eliminated and prove the usefulness of the proposed modulation method.

“…The only way to completely reduce the CMV in an MC is the use of rotating voltage space vectors for the synthesis of the output voltage in the MC. Elimination of the CMV in the MC by using rotating voltage space vectors has been investigated and presented by the authors of [15][16][17][18][19][20][21][22]. The authors of [17][18][19] present the SVM modulation method using only rotating input voltage space vectors.…”

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.
