“…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.…”

“…On the other hand, incorporating five rotating vectors in one switching period results in more switching actions and thus more switching losses, degrading the conversion efficiency. In turn in paper [30], the authors propose to use three rotating voltage space vectors without complicated trigonometric operation, which simplifies the modulation method providing elimination of the CMV as in the previous method. Application of the three rotating voltage space vectors causes that in the presented method, the input displacement angle cannot be controlled.…”

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.

“…Among them, the six rotating vectors in group III produce zero CMV [14]- [16]. However, their angular positions always change along with the input voltage, so using these vectors is not simple.…”

“…Nguyen and Lee proposed an effective modulation scheme, including an SVM method using only rotating vectors and a modified four-step commutation technique, to achieve zero CMV for MCs [15]. More recently, Lei et al suggested a simpler SVM method to accomplish zero CMV by adopting only three clockwise rotating vectors or counter-clockwise rotating vectors [16]. However, the performance of the MC when using this method is reduced significantly because the rotating vectors used are very far from the reference outputvoltage vector.…”

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.
