RISTwo simple overmodulation algorithms for space vector modulated three-phase to three-phase matrix converter
In this study, the potential of the space vector modulation (SVM) to control the matrix converter beyond its intrinsic voltage transfer ratio (VTR) limitation (0.866) is investigated. Afterwards, a simple space vector overmodulation method...
A Dynamic Model for Direct and Indirect Matrix Converters
Thecomplicatedmodulation algorithm and the high switching frequency are two main hindrances in the analysis and simulation of matrix converters (MCs) based systems. To simplify the analysis and accelerate the simulation ofMCs, a unique dynamic model...
Control of DFIG Wind Turbines Based on Indirect Matrix Converters in Short Circuit Mode to Improve the LVRT Capability
Nowadays, the doubly-fed induction generators (DFIGs) based wind turbines (WTs) are the dominant type ofWTs. Traditionally, the back-to-back converters are used to excite the rotor circuit of DFIG. In this paper, an indirect matrix converter (IMC...
PERFORMANCE AND STABILITY STUDY OF A TRIPLE DYNAMIC VOLTAGE RESTORER BASED ON MATRIX CONVERTER
Dynamic voltage restorer (DVR) is a type custom power devices which has been conventionally designed based on AC/DC/AC converters. This topology suffers from a bulky capacitor and the corresponding problems. So in this paper the matrix converter...
Very high gain three-phase indirect matrix converter with two Z-source networks in its structure
Nowadays, expansion of new energy sources and the necessity of integrating them with the utility grid require more advanced power electronic converters. Matrix converters (MCs) and indirect matrix converters (IMCs) are recent solutions, which offer...
Locality-sensitive hashing based multiobjective memetic algorithm for dynamic pickup and delivery problems
Compensating of voltage flicker and disturbance using Dynamic Voltage Restorer based on matrix converter
the voltage flicker and

A single-stage ballast for HID lamps with a buck chopper integrated direct matrix converter
This paper proposes the combination of low frequency square waveform (LFSW) ballasts with AC/AC converter topologies as a new electronic ballast for high intensity discharge (HID) lamps. The proposed circuit is a buck integrated matrix converter...
GA-Based Optimal LQR Controller to Improve LVRT Capability of DFIG Wind Turbines
, an Indirect Matrix Converter (IMC)
is proposed to control the generator. Compared with back-to-back converters, IMCs have
numerous advantages such as: higher level of robustness, reliability, reduced size and
weight due to the absence...
