This project focuses on a power electronics unit composed by a boost converter and a three-phase inverter for use in a photovoltaic generation in grid-connected applications. The main aim is to build a setup with its software controller for educational purposes. To achieve this goal, a Digital Signal Controller of Texas Instruments has been used, which is in charge of the control. C code is employed for the controller, which generates the signals that rule the converters by doing measurements on key electrical variables and processing them according to the application objectives. First of all, a complete theoretical analysis is made and a mathematical model of a system with a PV source the voltage level of which is boosted by a DC-DC boost convert and finally connected to the grid by a three-phase inverter.. This model is employed to design a suitable controller which is implemented on the DSC. To implement it, digital control and power electronics concepts are applied. Once the digital controller is coded, the complete circuit is simulated with Typhoon HIL software, and simulations are carried out in a safe environment to ensure that controller works as desired. The goal of this activity is to check the suitability of the design in a safe environment, and study the system response with its similarities and differences with the modeled system. Finally, the setup is prepared in the laboratory and experimental tests are carried out. The aim of the experimental tests is to show that controller works as desired and it can be used for educational purposes. Also, a study of the results is done to evaluate the performance of the controller. Each control loop is tested by applying steps on references variables and comparing the results with the theoretical values. These tests are carried on using different sampling and switching frequencies. MPPT algorithm is also tested to check if system can work permanently at MPP in different irradiance values.
