“…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.

“…However, the input filter produces a displacement angle between the source phase voltage and current [18]. This displacement angle will significantly degrade the IPF of the power source, especially at low VTRs, which may lead to severe powerfactor penalties [19]. Therefore, it is important to consider the IPF compensation problem along with CMV reduction.…”

The space vector modulation (SVM) method using only rotating vectors is very effective to suppress the common-mode voltage (CMV) for matrix converters (MCs). However, the effect of the input filter on the input power factor (IPF) has not been fully investigated when using this method. This study investigated the effect of the input filter on the displacement angle and proposes an IPF compensation strategy for the zero CMV-SVM method in MCs. The proposed strategy analyzes the duty cycles of rotating vectors under the IPF-compensation condition. Through this analysis, the proposed strategy adjusts the zero vector by using a set of three counterclockwise-rotating vectors or three clockwise-rotating vectors to make all the duty cycles non-negative, ensuring that the zero CMV-SVM method can be applied to compensate the IPF for the MCs. This study also determines the condition to achieve unity IPF for the main power source and the maximum allowable IPF if the above condition is not met. Finally, experimental results are provided to validate the theoretical study. INDEX TERMS Matrix converter, space vector modulation, zero common-mode voltage, rotating vector, input power factor.
