Optimal modulation of indirect Z-source matrix converter
The 2010 International Power Electronics Conference - ECCE ASIA -, 2010Z-source energy conversion is a recent concept introduced for adding voltage-boost functionality to the otherwise buck-only dc-ac inverter. The same concept can equally be extended to other converter topologies including the indirect ac-ac matrix converter, where only a single Z-source impedance network needs to be inserted to its intermediate dc-link.

Indirect matrix converter for AC induction motor drives
2009 Brazilian Power Electronics Conference, 2009A matrix converter to directly connect a three-phase load to a three-phase power source using eighteen IGBTs and eighteen fast diodes is presented in this paper. The IGBTs are connected in a common-emitter (CE) configuration by versatile blocks, able to be used in other topologies such as sparse matrix converters and conventional matrix converters. The

Analysis of Current Control Techniques in an Indirect Matrix Converter
2018 IEEE International Conference on Automation/XXIII Congress of the Chilean Association of Automatic Control (ICA-ACCA), 2018In recent years new modulation and control techniques have appeared for matrix converters, which take advantage of new technological advances in microcontrollers and signal processors. This article makes a comparison of two control techniques for an indirect matrix converter. The comparison is done in simulation using Matlab-Simulink.

A carrier based PWM algorithm for indirect matrix converters
2006 37th IEEE Power Electronics Specialists Conference, 2006In this paper, the indirect matrix converter is systematically studied with the single-pole-multiple-pole representation. A carrier based PWM algorithm is developed in two steps. First, the continuous modulation functions for all the throws are derived based on the desired sinusoidal input currents.

Realization of a three-phase indirect matrix converter with an indirect vector modulation method
IEEE 34th Annual Conference on Power Electronics Specialist, 2003. PESC '03., 2003This paper presents the simulation and measurement results of a three-phase 5 kVA vector modulated indirect matrix converter (IMC). Functionally the IMC is very similar to the direct matrix converter (DMC) but it has separate line and load bridges.

DC/DC Boost Converter Functionality in a Three-Phase Indirect Matrix Converter
IEEE Transactions on Power Electronics, 2011An indirect matrix converter (IMC) connected with two input power sources is proposed: a gasoline generator as the main ac power supply and batteries as the secondary power source. The IMC is small in size because of having a dc-link part without an electrolytic capacitor.

An indirect matrix converter with a cost effective protection and control
2005 European Conference on Power Electronics and Applications, 2005The cost of protection circuits and transducers for protection and control purposes play an important part when evaluating the potential of a converter topology for mass production. Direct power converters are known to require minimum size of the passive components in the input filter, but they require a large number of semiconductor devices and the ...
