The matrix converter is an array of controlled semiconductor switches that connects directly the m-phase source to the n-phase load. The Matrix Converter (MC) evolved from the forced commutated cycloconverters and has been extensively investigated for more than three decades in the last few years. An increase in research work has been observed, bringing this topology closer to the industrial application. The major contributions in the fundamental topic areas such as the development of the topology and semiconductor devices are compiled and presented. Along with direct matrix converter topologies, indirect matrix converter topologies and matrix converter topologies with reduced number of switches, Z source matrix converter topologies are also explored in this paper. Disadvantage of conventional matrix converter having either buck or boost capability can be resolved by Z-source matrix converters. Extensive research has been done on different matrix converter topologies and its modulation methods to increase the output to input voltage ratio and to decrease the stress on the switching devices.
