The Mathematical Model

In the recent years, three-level rectifier becomes an attractive rectifier replaced the two-level rectifiers. This rectifier provides many advantages, such as sinusoidal input current which contains low harmonics, unity power factor, bi-directional power flow, low voltage and switching loss for each switch. This paper presents a modelling and execution of the three-level rectifier for improvement of power quality under different loading based on voltage oriented control. The mathematical model and the control design were presented in this paper for the current inner loop and voltage outer loop, respectively. In order to evaluate the operation of the three-level rectifier under different conditions, the model was simulated by using MATLAB/Simulink. The experiment has been used to confirm the operation of the rectifier and its controller. The simulation and experimental results show that the excellent performance under steady-state and dynamic load variations was achieved; the unity power factor and pure sinusoidal in the grid side has also been accomplished.

Source Current

The extensive usage of power electronic components creates harmonics in the voltage and current, because of which, the quality of delivered power gets affected. Therefore, it is essential to improve the quality of power, as we reveal in this paper. The problems of load voltage, source current, and power factors are mitigated by utilizing the unified power flow controller (UPFC), in which a combination of series and shunt converters are combined through a DC-link capacitor. To retain the link voltage and to maximize the delivered power, a PV module is introduced with a high gain converter, named the switched clamped diode boost (SCDB) converter, in which the grey wolf optimization (GWO) algorithm is instigated for tracking the maximum power. To retain the link-voltage of the capacitor, the artificial neural network (ANN) is implemented. A proper control of UPFC is highly essential, which is achieved by the reference current generation with the aid of a hybrid algorithm. A genetic algorithm, hybridized with the radial basis function neural network (RBFNN), is utilized for the generation of a switching sequence, and the generated pulse has been given to both the series and shunt converters through the PWM generator. Thus, the source current and load voltage harmonics are mitigated with reactive power compensation, which results in attaining a unity power factor. The projected methodology is simulated by MATLAB and it is perceived that the total harmonic distortion (THD) of 0.84% is attained, with almost a unity power factor, and this is validated with FPGA Spartan 6E hardware.
