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

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.

Research on a New Indirect Space-Vector Overmodulation Strategy in Matrix Converter
IEEE Transactions on Industrial Electronics, 2016The traditional space-vector pulsewidth modulation (SVPWM) maximum voltage transfer ratio (VTR, i.e., the ratio of the output voltage fundamental amplitude to the input voltage fundamental amplitude) is 0.866 in a linear modulation region. In this paper, the output voltage fundamental amplitude and total harmonic distortion (THD) affected by a basic ...

Open-circuit fault diagnosis for rectifier stage in indirect matrix converter
IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016In order to detect open-circuit fault in rectifier stage, a fault diagnosis method applied to indirect matrix converter (IMC) is proposed in this paper. Firstly, the theory and feature of space vector modulation (SVM) are introduced. Then, detailed circuit analysis of IMC under fault condition is fully studied, and from the view of energy transfer, the
