Conventional matrix converters (MCs) have limited voltage gain that is less than 0.866, whether for direct MC (DMC) or indirect MC (IMC). The Z-source matrix converters (ZSMC) overcome the voltage gain limitation of the traditional MC and achieve buck andboost operation with reduced switches count, therefore achieving low cost, high efficiency, and reliability, compared to the back-to-back converter. Furthermore, it will leads to more MC industrial applications. This paper presents an up to date comprehensive overview of the different Z-source matrix converter topologies and their configurations, circuit analysis, modulation schemes, and applications. This study offers a comprehensive and systematic reference for the future development of the Z-source matrix converters.Keywords: Z-source converter, Quasi-Z-source converter, Z-source indirect matrix converter, Z-source direct matrix converter.I. 0885-8993 (c) topology of the MC, they are called Z-Source Indirect Matrix Converter (ZSIMC) and Z-Source Direct Matrix Converter (ZSDMC). Therefore, it is possible to overcome the low voltage gain challenge of the traditional MC; in addition, the ZS/QZS network allows the short circuit, which makes the ZSMC commutation easier. As a result, the ZSMC provides a low-cost, reliable, and highly efficient structure for buck and boost ac/ac conversion. Moreover, there are two different configurations of the ZSIMC topology depending on the location of the ZS/QZS network. The ZS/QZS network can be located between the rectifier and inverter of indirect matrix converter at the intermediate dclink, the voltage gain is extended, but it is not all-silicon-solution and will cause larger size and heavier weight (it requires large inductors and capacitors in the dc-link) than the conventional IMC. The other option, where the ZS/QZS network is inserted between the input ac source and rectifier of the indirect matrix converter to achieve all-silicon solution. This configuration can achieve high voltage gain with a small ZS/QZS network, but it requires a large number of switches, so it is at the result of higher cost. This paper will present an updated overview of the different Zsource matrix converter topologies including the ZSIMC with its all-silicon and not all-silicon configurations and also the ZSDMC.

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.

This paper has researched the vector modulation strategy of three-phase to single-phase matrix converter (3-1 MC) with an active power decoupling capacitor, and focused on asymmetric two-phase current vector modulation of 3-1 MC's virtual inverter. Each work state of 3-1 MC during a switching period is obtained based on the analysis of 3-1 MC's voltage sectors, current sectors and the input current signal at unit power factor. The input power keep constant after active power decoupling, therefore the high power factor is achieved easily according to power factor correction (PFC) technique in rotating coordinate system. In the PFC control system, 3-1 MC's active current and negative current can be regulated independently. Finally, an example of high power factor 3-1 MC used in the airport is conducted in MATLAB. The results of stimulation indicate that the method of power decoupling is feasible, and the unit power factor is achieved.Index Terms -three-phase to single-phase, matrix converter, active power decoupling, PFC, vector modulation I.
