“…To reduce the CMV of the IMC, non-zero vector approaches are introduced to control the inverter stage, i.e. only active vectors are used to generate the desired output voltage [12], [13], [16], [18]. Among non-zero vector approaches, the near state PWM technique is preferred to others due to its advantages, such as smaller total harmonic distortion (THD) of the line-to-line output voltage and low switching losses [11].…”

“…From (18) and 20, it should be noted that the duty ratios of the rectifier and inverter stages must be non-negative and lower than or equal to unity. From (24), the proposed strategy is suitable to drive the IMC operating at a high VTR range.…”

“…Avoiding the separation of the two operation ranges, Tsoupos and Khadkikar suggested a weighing factor to the seamless transition between the low and high VTR operation regions [17]. In [18], a modulation method is proposed to both reduce the CMV and the output voltage and current harmonics distortions for a five-leg IMC fed open-end winding load. Li et al presented a new SVM method based on the concept of open-current vector to suppress the peak value of CMV without degraded the output performance [19].…”

“…The amplitude of 2f c is the highest among all the harmonic components, up to 0.93 under the condition of m = 0.5, followed by the component of f c ± 6f in with the amplitude of 0.53. According to literature [18][19][20], high-frequency common-mode voltages are the main cause of bearing damage, winding fault, electromagnetic interference. The above analysis can accurately describe the amplitude of these common mode voltages, thus providing reference for the suppression of common mode voltage.…”

Abstract:In a matrix converter, the frequencies of output voltage harmonics are related to the frequencies of input, output, and carrier signals, which are independent of each other. This nature may cause an inaccurate harmonic spectrum when using conventional analytical methods, such as fast Fourier transform (FFT) and the double Fourier analysis. Based on triple Fourier series, this paper proposes a method to pinpoint harmonic components of output voltages of an ultra sparse matrix converter (USMC) under space vector pulse width modulation (SVPWM) strategy. Amplitudes and frequencies of harmonic components are determined precisely for the first time, and the distribution pattern of harmonics can be observed directly from the analytical results. The conclusions drawn in this paper may contribute to the analysis of harmonic characteristics and serve as a reference for the harmonic suppression of USMC. Besides, the proposed method is also applicable to other types of matrix converters.

“…In such a configuration, it is essential to eliminate the CMV that is inevitably created by usual PWM control strategies [19], [20]. Some literature reported on these issues of circulating currents and CMV cancellation in the OEW fed by dual inverters [18]- [21], and by DMCs [22], [23]. However, the main focus of this paper is not the CMV and circulating currents, but to get the optimum condition for sharing the power of both MCs by controlling the reference voltage space vectors and analyze the system.…”

In this paper, space vector pulse width modulation (SVPWM)-based algorithms for a five-phase open-end load fed from dual matrix converter (DMC) have been proposed. In the presented modulation methods, the reference output voltage vector is synthesized from two three-to-five phase matrix converters at both the ends of the load. Depending on the power-sharing of the two MCs, two proposed modulation methods are defined as equal reference sharing (ERS) and unequal reference sharing (URS). The performance of ERS and URS for the three-to-five phase DMC drive is compared. Performance comparison is based on the total harmonic distortion in the output voltages and the percentage of the voltage transferred from the source to the load, for the full linear modulation index (MI) range. Common mode voltage and zero sequence current in the load are also discussed. The efficiency of the ERS and URS is compared. It has been observed that the proposed ERS scheme offers better performance compared with URS for most of the MI values. The suggested modulation techniques are implemented in MATLAB/Simulink. The hardware setup is developed and control algorithm is implemented using dSPACE working in conjunction with the FPGA interface board for practical validation.
