    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 research is concerned with the implementation of a low-cost single-phase grid connected PV system including active power filtering functionality. The system is able to transfer surplus power to the grid, to compensate both reactive power and harmonics for nonlinear loads resulting in nearly unity power factor and nearly sinusoidal grid current. The system is controlled by a low cost dSPIC30F4011 microcontroller. Rectification and inversion mode operation is described. Software and hardware design of the system is given. The merit of the proposed system is simplicity especially for grid synchronization using zero crossing in conjunction with a sinusoidal look-up table. The process of reference current generation is fully described and demonstrated by experimental waveforms. Simulation and experimental results are compared in order to validate the proposed technique under various conditions such as low and high solar irradiation.
