High efficiency Indirect Matrix Converter topologies
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013This paper discusses new three-phase ac-ac Indirect Matrix Converter (IMC) topologies featuring higher power efficiency than conventional IMCs. Initially, a new Inverting-link Matrix Converter (ILMC) with lower conduction power losses than a standard ILMC for voltage step-down operation is proposed.

Indirect Three level Matrix Converter
7th IET International Conference on Power Electronics, Machines and Drives (PEMD 2014), 2014An indirect capacitor clamped multi-level matrix converter has been proposed in this paper. In comparison to the conventional matrix converter the proposed converter makes available half line voltages in addition to the line voltages at the converter output.

Simplified quasi‐Z source indirect matrix converter
International Journal of Circuit Theory and Applications, 2014SummaryConventional matrix converters have a limited voltage gain less than 0.866 and also require many power switches and additional input filter that ensures a low input current harmonics to the grid. Quasi‐Z source (qZS) indirect matrix converter can provide high voltage gain and ensure a sinusoidal input current without additional input filter ...

A novel quasi‐Z‐source indirect matrix converter
International Journal of Circuit Theory and Applications, 2013SummaryA new type of three‐phase quasi‐Z‐source indirect matrix converter (QZS‐IMC) is proposed in this paper. It uses a unique impedance network for achieving voltage‐boost capability and making the input current in continuous conduction mode (CCM) to eliminate the input filter.

Comparison of Two Overmodulation Strategies in an Indirect Matrix Converter
IEEE Transactions on Industrial Electronics, 2013This paper discusses two overmodulation controls, namely, square wave and trapezoidal, in the indirect matrix converter (IMC) for motor drive application. The differences between these two modulations are analyzed based on the output-input voltage transfer ratio (VTR), the efficiency, and the current total harmonic distortions under two load conditions.

Open-circuit behavior analysis for indirect matrix converter
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017Indirect matrix converter (IMC) has attractive advantages such as lack of dc-link electrolytic capacitor, bidirectional power flow and high power density. Aiming at faulty condition, this paper presents an analysis work for indirect matrix converter (IMC), which could make contribution to detecting the failure accurately.

Comprehensive analysis of Matrix Converters: Indirect topology
2014 15th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA), 2014Matrix Converters (MCs) are developed to remove the use of bulky DC links in AC-DC-AC converters to achieve an adjustable AC-AC conversion system. Recently, different MC topologies have been proposed and developed which have their own advantages and disadvantages. Two main topologies of MCs are direct and indirect ones.

Comparison of Losses Between Matrix and Indirect Matrix Converters With an Improved Modulation
2010 IEEE International Symposium on Industrial Electronics, 2010Matrix (MC) and indirect matrix (IMC) converters are direct three-phase to three-phase power converters providing variable frequency and amplitude control of their output voltage. These converters are compact solutions which can be used on industrial adjustable speed drive applications for induction motors.

PWM algorithms for indirect matrix converter
Proceedings of The 7th International Power Electronics and Motion Control Conference, 2012This paper presents a novel PWM algorithm for indirect matrix converter (abbreviated to IMC) is proposed. Generally, PWM algorithm for the rectifier is based on two larger source line voltages without zero vectors. In this paper, when considering the PWM algorithm for the rectifier, the inverter and motor can be seen as constant current load in DC link.
