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.

Fixed Slope Carrier PWM for Indirect Matrix Converter
2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia), 2018Indirect matrix converter (IMC) typically requires zero current commutation (ZCC) at its rectifier stage. This paper proposes a fixed slope carrier modulation for IMC. According to homothetic triangle, the modulating functions in the inverter stage are scaled by the rectifier stage to accomplish ZCC.

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.

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

High-Gain-Integrated Switched Capacitor Indirect Matrix Converter
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2019An ultrasparse matrix converter (USMC) is a derived form of an indirect matrix converter having a less number of switches. Even though it has unidirectional power flow capability, it is a quite appropriate candidate for specific applications, such as wind-energy systems, electrohydrostatic actuators, variable speed drives, and so on.

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.

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.

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.

Predictive Control of Neutral-Point Clamped indirect matrix converter
2017 Iranian Conference on Electrical Engineering (ICEE), 2017In this paper, a Neutral-Point Clamped (NPC) based indirect matrix converter is proposed in order to decrease the Total Harmonic Distortion (THD) of the input and load currents. This converter produces three-level output voltages which are suitable for high-power medium-voltage applications.
