“…It needs complex calculations and tables to synthesize the reference input current and the reference output voltage. The implementation of SVPWM method needs to do some steps [7,8,[15][16][17]: The adjacent active and zeros vectors are needed to synthesize the reference input current and reference output voltage vectors. Then, the duty cycles of these active and zero vectors are calculated and the switching patterns are arranged according to the input current and voltage vectors.…”

In this paper, a novel approach to realize the carrier-based pulse width modulation (CBPWM) method for indirect matrix converter (IMC) is presented. The advantage of the proposed CBPWM method is that only one triangular carrier signal with constant gradient falling and rising edges is used to generate the PWM to the power switches in both the rectifier and the inverter stages of IMC. The analysis of the proposed CBPWM method is based on the space vector approach and the relationship between CBPWM and space vector pulse width modulation (SVPWM) methods is provided. In this paper, four CBPWM methods called: sinusoidal PWM, third harmonic injection PWM, symmetrical PWM and discontinuous PWM are presented. These different CBPWM schemes are established according to the distribution of zero vectors and the switching pattern of the SVPWM method. The comparison of output voltage performance with different CBPWM schemes are investigated. Compared to the conventional method the calculation time of the proposed method is reduced around 50%. Concretely, the calculation time of the SVPWM method is 45 μs, while the calculation time of the proposed method is 22 μs. The experiments have been carried out to show the effectiveness of the proposed method.

“…Then an additional algorithm is needed to combine the two modulation schemes. 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.…”

“…In comparison to traditional back-to-back converters, MCs offer more compact and reliable operation owing to the absence of bulky electrolytic capacitors [1], as shown in Figure 1. Therefore, MCs have garnered significant research interest in industry, particularly the aircraft, electric-vehicle, and wind-generation industries [2]- [4]. However, MCs have not been widely applied in practice owing to several issues affecting input-filter design, bidirectional-switch technology, commutation techniques, and the common-mode voltage (CMV) [5].…”

“…However, MCs have not been widely applied in practice owing to several issues affecting input-filter design, bidirectional-switch technology, commutation techniques, and the common-mode voltage (CMV) [5]. Among these problems, the CMV between the motor neutral point and power supply ground is the main source of motor winding failure and bearing damage [6]- [8]. Furthermore, it also causes noise and electromagnetic interference problems, affecting surrounding electronic equipment [9].…”

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.
