One important reason is its high control complexity. It is therefore relevant to propose a simpler but efficient modulation scheme, similar as three phase VSI modulators with the well-known symmetrical carrier-based ones. The modulation presented in this paper is equivalent to a particular Space Vector Modulation (SVM) and takes into account harmonics and unbalanced input voltages, with the same maximum voltage transfer ratio (86%). The aim of this work is to propose a simple and general pulse-width-modulation method using carrier-based modulator for an easier matrix converter control. Furthermore, a simple duty cycle calculation method is used, based on a virtual matrix converter. Finally, simulations and experimentations are presented to validate this simple, original and efficient modulation concept equivalent to matrix converter SVM.

“…The dynamic model of the passive load is defined as following: (2) where Rl and Ll are the load resistance and inductance, respectively. Using the forward Euler discretization for (2) with a sampling period Ts, the 27 predicted load currents ( + 1) corresponding to the 27 output voltage vectors ( + 1) of the MC can be expressed as the following equation: As the control target is to regulate the load current, the cost function for the load current can be given as following:…”

“…During the past decades, matrix converters (MCs) have become an attractive converter to alternate the back-to-back converter due to its superior advantages such as sinusoidal input/output waveforms, controllable input power factor, bidirectional power lfow capability, and a compact power circuit [1], [2]. Amon� the MC� s modulation methods, the predictive current control (PCC) has recently emerged as a feasible and competitive method compared with the classic linear controllers [3], [4].…”

-Predictive current control (PCC) is an effective method to control matrix converters (MCs) due to its advantages such as simplicity, fast dynamic response, and flexibility to control different variables. However, the high amount of calculations for the PCC is an obstacle for its real application. To overcome this problem, this paper proposes a simplified PCC method for MCs by utilizing the sector distribution. In addition, the proposed method reduces the peak value of common-mode voltage (CMV) to 42% by using a mediumvalued phase voltage to generate the zero vectors. Simulation results are shown to validate the effectiveness of the proposed PCC method.

“…There are no internal current control loops or no PWM modulator block in DPC. The main disadvantage of the DPC strategy is the resulting variable switching frequency, which could complicate the design of the power converter and the AC harmonic filter, decrease the using time of the devices and increase cost and power loses (Nguyen and Lee, 2010).…”

In this paper, the proposed new direct power control strategy (DPC) is based on predictive control theory to achieve direct control of instantaneous active and reactive power of the converter. Based on two stage matrix converter's (TSMC) direct driven permanent magnet synchronous wind power systems is studied, the proposed predictive direct power control (P-DPC) strategy is applied to the system to improve the dynamic performance of the system. For this aim, based on predictive control principle, calculated the input voltage vector average of the inverter at the beginning of each switching cycle, eliminate the active and reactive power tracking errors at the end of switching period. Compared with the conventional DPC strategy, the proposed control strategy possesses such advantages without phase locked loop, and its switching frequency is fixed. Finally, the simulations works is developed to validate the proposed method. By using MATLAB simulation platform, the simulation results show that the P-DPC strategy can achieve the good decoupling control for the active power and reactive power, can realizes unit input power factor and provide fast dynamic response.
