Fixed-speed wind turbines for generating electricity are also important because they are clean energy and do not pollute the environment. Developing maximum wind energy tracking and increasing DC voltage to optimal values is also an important factor designers must consider so that the power from generators connected to wind turbines can function efficiently. Therefore, in this researcher paper proposed a single-channel dc/dc boost converter control, three forms of algorithms consisting of neural networks, fuzzy algorithms and PID algorithms. The purpose of bringing these algorithms controlled because they wanted to compare the response and voltage control performance of the single-channel DC/DC boost converter to be associated with a three-phase inverter that controls PWM signal modulation with space vector technique. However, the principles and methodologies in this article are presented to simulate the algorithmic response using the MATLAB/Simulink program and compare it with the prototype mechanism. A comparison of the response performance and voltage regulation of the single-channel DC/DC boost converter showed that the three algorithms have different advantages and disadvantages but can be used together to achieve high efficiency.

This paper presents the control of grid-connected single-phase inverters with vector control technology based on the D-Q spindle reference frame for photovoltaic systems. This method begins with converting the grid current of the reference sinusoidal signal to a 90degree phase angle and converting it to a DC signal using the clack conversion principle. The aim of this research is to control the current amount of the D-axis vector and adjust the motion angle lag and lead the Q-axis vector. This mechanism control technology uses a microcontroller TMS3020F28379D This allows control of the inverter modulation to supply active and reactive power to the grid. As a result, the power factor in the system can be controlled close to unity. The simulation results using MATLAB / Simulink, compared to the prototype mechanism can confirm satisfactory accuracy.

This research paper proposes a power balance optimization topology for a five-level cascaded H-bridge inverter with a phase shift technique. This topology uses two phase-shifted sine waveforms 180 degrees apart to modulate the two triangular waveforms. These two triangular waveforms are assigned a 90-degree phase shift. When the outputs of the two H-bridge inverters are connected in series, the total output waveform is 5 levels. The principles and methods of this research will focus on a cascaded H-bridge inverter with photovoltaic sources. Two independent units are connected in series to allow linear and non-linear loads at a maximum one-kilowatt rating. However, the researcher will create a prototype mechanism to test the power balance and power distribution efficiency of the two inverters compared with the simulation results using MATLAB/Simulink. Nevertheless, the results showed that the power balance efficiency could be improved, resulting in the mean efficiency of both inverters of 96%. When the harmonics were measured, the load was not Linear produced third- and fifth-order harmonics greater than linear load. This research confirms that the simulation with MATLAB/Simulink program and the prototype is correct and acceptable.
