“…Matrix converters that can directly convert an AC power supply voltage into an AC voltage of variable amplitudes and frequencies without large energy storage have been actively investigated [3][4][5][6][7][8][9][10][11]. These matrix converters have advantages of high efficiency, long lifetime and downsizing in comparison to a conventional AC/AC converter.…”

This paper proposes to apply an AC/AC direct converter topology for servo systems. In the conventional AC/AC converter which consists of a PWM rectifier and a PWM inverter, the p-n junction temperature becomes high at the low output frequency or the servo-lock operation because the output current concentrates at the specific switching devices in the inverter. On the other hands, the AC/AC direct converter such as matrix converter is able to reduce the junction temperature of the switching devices. In this paper, the junction temperature of each type of the converters is evaluated by using the thermal simulation of the p-n junction. The output frequency of the conventional matrix converter and the indirect matrix converter are 1/8 and 1/2 smaller compared to the conventional AC/AC converter when the same temperature ripple is obtained in low output frequency region. That is, when these converters use the same current rating device, the matrix converter can operate at a frequency lower than the conventional AC/AC converter.

“…In these simpler commutation schemes, the IMC is either operated at zero current commutation of the input stage, zero voltage commutation of the output stage, or a combination of both, for example to balance the switching losses between the input and output stage (75) , which is described in detail in (33) (52) (76). The zero voltage commutation of the IMC is less known and was tested by Itoh et al in 2009 (77) .…”

The Matrix Converter (MC) evolved from the forced commutated cycloconverters and has been extensively investigated for more than thirty years. In this publication, the milestones in research on MCs in academia and industry are reviewed and presented chronologically and thematically ordered. The major contributions in the fundamental topic areas such as the development of the topology, topological extensions, commutation, modulation, loss calculation, control, or filtering and EMC are compiled and then expanded with examples of the latest activities in the corresponding field of research. In addition, an overview of the publicly reported research on MCs in industry is provided and the development of the commercialized MCs is briefly summarized. This review concludes with a brief comparison of the MC with the voltage source converter and a discussion of the current status of the MC technology and its future potential.

“…Although this technique can avoid commutation of the high output currents, the reduction of the switching numbers is not guaranteed during some sampling cycles. Itoh et al [17] introduced a control method that eliminates the switching losses in the inverter stage of an IMC. However, the total switching losses in the converter do not decrease, because the switching losses of the inverter stage are moved to the rectifier stage by adopting the zero voltage switching operation in the inverter stage instead of the rectifier stage.…”

In this paper, an effective carrier-based modulation (CBM) strategy to reduce the switching losses for indirect matrix converters (IMCs) is presented. The discontinuous pulse width modulation method is applied to decrease the switching numbers in one carrier cycle, and an optimum offset voltage is selected to avoid commutations of the high output phase currents. By decreasing the switching numbers along with avoiding commutation of the high currents, the proposed CBM strategy significantly reduces the switching losses in IMCs. In addition, the proposed CBM strategy is independent of load conditions, such as load power and power factor, and it has good performance in terms of the input/output waveforms. Simulation and experimental results are provided to verify the effectiveness of the proposed CBM strategy.
