Two 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 ...
Controller Design Using Ant Colony Algorithm for a Non-inverting Buck–Boost Chopper Based on a Detailed Average Model
In this article, the non-inverting buck–boost converter and its operation modes are scrutinized. The closed-loop stability of the converter in buck and boost modes is analyzed, and the necessity of using an appropriated ...
Modulation Techniques for Common-Mode Voltage Reduction in the Z-Source Ultra-Sparse Matrix Converters
Common-mode voltage (CMV) is known as a major cause of premature motor failures. The form and amplitude of the CMV generated by any converter depends on both the circuit topology and modulation technique. Among single stage ...
Optimum Switching Pattern of Matrix Converter Space Vector Modulation
This paper presents an optimum switching pattern for the space vector modulation (SVM) of matrix converters based on a genetic algorithm. The possibility of choosing the sequence of active duty cycles, and the ability to ...
Improved grid voltage sensorless control strategy for railway power conditioners
Rapid development of high-speed trains confronts the power grid with serious power quality problems. In this study, to compensate power quality, an improved grid voltage sensorless control method for the railway power ...
Voltage sensorless improved model predictive direct power control for three-phase grid-connected converters
Despite distinctive advantages such as fast dynamic, simple concept and ease of implementation, model predictive direct power control (MPDPC) suffers from some major drawbacks. First, in order to provide sinusoidal currents ...
