“…The relationship between the maximum voltage transfer ratio and the system parameters can be plotted using equation (14) (as shown in Figure 7), in which f o is the output frequency. Figure 7A shows that when the resistive load parameter is constant, the maximum voltage transfer ratio q max of the 3-1MC system is determined by the output frequency f o and the decoupling inductor L c .…”

Summary A 6‐switch three‐phase to single‐phase matrix converter (3‐1MC) with independent neutral line is directly coupled to the input side through bidirectional switches, and the output ripple power produces low‐frequency harmonics in the input side that are difficult to filter out. In this paper, the expressions of the frequencies and contents of the low‐frequency harmonics are derived based on the principle of input‐output instantaneous power conservation. Then, a 3‐1MC topology with decoupling unit is studied and the working principle and process of improving the input performance are analyzed. Second, based on the relationship between the output side and the decoupling side modulation function, the influence of the introduction of the decoupling unit on the maximum voltage transfer ratio of 3‐1MC is studied. The relationship between the voltage transfer ratio and parameters such as decoupling unit and output frequency is derived in detail. It is proved that maximum voltage transfer ratio of the topology is a nonlinear function related to system parameters. Then, the operating principle and modulation method of 3‐1MC are discussed. A double‐side current closed‐loop control strategy based on space vector modulation under power decoupling conditions is proposed. Finally, an experimental platform is built to verify that the 3‐1MC with decoupling unit can suppress the low‐frequency harmonics in the input current at different output frequencies and effectively improve the performance of the input side. The results show that the 3‐1MC with the decoupling unit is beneficial for use in single‐phase applications.

“…In the software solution, to achieve the CMV elimination, a modification of the modulation methods is applied. A majority of these methods are focused on modification of classic space vector modulation (SVM), applying active and zero voltage space vectors to synthesize output voltage in the MC [8][9][10][11][12][13][14]. The zero vectors resulting in the highest value of CMV are replaced by using combinations of active vectors or rotating space vectors, that are related to an increase in the number of switch commutations.…”

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.

The matrix converter (MC) is the n-phase input and m-phase output power electronic system. To synthesis the controllable sinusoidal output voltage and input current with controllable input displacement angle, the pulse width modulation method (PWM) is used in the MC. During the modulation process a problem of the common mode voltage (CMV) exists. The elimination of the CMV in three-to-six-phase MC by usage of only rotating voltage space vectors is analyzed in the paper. The carrier based implementation of the space vector modulation (SVM) with Venturini modulation functions is applied to the control of the three-to-six-phase MC. Entire elimination of the CMV in three-to-six-phase MC is presented in the paper. The simulation and experiment results confirm utility of the proposed modulation method.
