Modeling and simulation of DC to DC boost converter using single phase matrix converter topology

The main objective of this work is to model and simulate DC to DC Boost Converter using Single Phase Matrix Converter (SPMC) topology using MATLAB/Simulink (MLS). The output voltage is controlled by using Pulse Width Modulation (PWM) technique. Four pairs of Insulated Gate Bipolar Transistor (IGBT) is used as the switching device where for each pair, it is located in parallel and opposite direction. Safe commutation technique is performed in preventing voltage spike at the output. Through the simulation, at switching frequency of 25kHz, the model is able to step up its input voltage about two times larger and all of the results achieved a good agreement with the principle of four quadrant operation. It is also realized that without the implementation of safe commutation technique, spikes were generated and the model is unable to boost its input voltage. All of the selected results from the analysis which includes variation of quadrant, switching frequency, duty cycle and resistive load are presented in this paper.

Development of four quadrant operation of DC to DC converter using single phase matrix converter

<span>Single-Phase Matrix Converter (SPMC) is an advanced circuit topology that offer advantages such as the capability to regenerate energy back to the input, sinusoidal input and output current and a manageable input current displacement factor. By considering the opportunity of an advanced SPMC topology, further exploration on DC to DC operation is proposed. The four-quadrant operation of switching algorithm was developed to control the SPMC circuit. The voltage and current profile of each quadrant was investigated to validate the proposed switching control algorithm. As part of four quadrants DC to DC operation, the safe commutation switching algorithm was also developed in order to solve the commutation problem due to the used of an inductive load. The pulse width modulation (PWM) techniques was utilized to synthesize the output of the proposed converter. Results from MATLAB/Simulink are presented to validate the proposed circuit operation.</span>

Novel Control Strategy of Single Matrix Traction Converter – Variable Switching Frequency

This paper describes research into a novel control strategy of traction converter for the AC-Trolley Line with the middle frequency transformer (MFT). Attention is paid to the problematics of finding a suitable control algorithm that will provide minimal magnetic saturation. This could be ensured by variable pulse widths, determined according to the actual value of input voltage. Special attention is focused on the single-phase matrix converter topology and the best commutation solution. Two basic methods of controlling the switches in the matrix converter are discussed. The first method requires some knowledge of the converter output current polarity and the second method assumes some knowledge of the input voltage polarity. In addition, the article describes the switching method in uncertain states – when the voltage or current cross zero. Moreover, the paper presents a new modular topology with several separate middle frequency transformers. The proposed algorithm is described and implemented in the laboratory model.

Simulation and Implementation of Single Phase Boost – Buck Rectifier Using SPMC Topology with Reduced Input Current THD

Simulation of single phase buck boost rectifier with reduced input current THD using single phase matrix converter topology is describing in this paper. Due to the bidirectional feather the operation for buck-boost rectifier can be made through matrix converter topology. And this is possible by the proper switching algorithm to control the switches for their boost and buck operation. The input current nature is almost sinusoidal with low current total current harmonics and the level of THD is below than limit that was defined in the standards of IEEE. With the proper variation in modulation index corresponding changes in the output voltage is observed of buck-boost rectifier. For the synthesis of the output voltage Pulse width modulation (PWM) technique is used. The simulation results using MATLAB/Simulink are providing to validate the feasibility of this proposed method

Comparison of Central Dimmer Systems Based on Multiple-Tapped Autotransformer and High-Frequency Switching Converter

This paper compares two central dimmer system technologies used in street lighting. These dimmers are utilized in adaptive lighting systems based on high-intensity-discharge lamps and magnetic ballasts. The first technology is based on a multiple-tapped autotransformer which is commonly used for these types of installations. The second technology is based on a high-frequency switch converter (more specifically in a single-phase matrix converter topology) and represents a novelty for this type of application. Tests were conducted to determine the main features of both dimmer technologies, and the obtained results are presented.
