Exploring the Theoretical Limit of Voltage Transfer Ratio of Matrix Converter Under the Constraint of Rotating Vector

Review and Case Study on Control of Induction Motor Using High-Level Converter

“…In 1983, Rodriguez introduced the "fictitious DClink" concept as a novel modulation approach for DMCs [36]. This indirect technique divides the matrix converter into rectifier and inversion stages, effectively allowing for an elevation surpassing the 0.866 limits observed in other techniques for maximum voltage transfer ratio [37]. Ziogas et al's research contributions in 1985-1986 elevated the max voltage transfer ratio to 1.052, albeit at the compromise involving distortion in low-frequency current harmonics [38].…”

Multiple load operation of indirect matrix converter for different frequencies using symmetrical space vector modulation

“…After that, in order to improve the output voltage quality and voltage transfer ratio (VTR) in the linear modulation region and to reduce output harmonic distortion and the peak common‐mode voltage (CMV), recently some improved control schemes have been introduced 32–34 . Recently, a new control strategy for IMCs referred to as discontinuous pulse width modulation (DPWM) based on active‐current vector amplitude characteristics has been introduced in the literature to reduce common‐mode voltage (CMV) 35 .…”

[32][33][34] Recently, a new control strategy for IMCs referred to as discontinuous pulse width modulation (DPWM) based on active-current vector amplitude characteristics has been introduced in the literature to reduce common-mode voltage (CMV). 35 Also, to compensate the input power factor (IPF) for the MC's and to determine the condition for unity IPF by analyzing the duty cycles of rotating vectors and ensuring the zero CMV, an advanced control strategy has been reported.…”
