Resumen
CONTROL OF POWER CONVERTER IS BEING WIDELY STUDIED TO PROPERLY MANAGE THE VARIABLES AND CONVERT THE ENERGY TO REACH THE SETTLED GOALS. PARTICULARLY, THE INSERTION OF RENEWABLE ENERGIES ON THE AC MAINS HAVE FOCUSED THE ATTENTION OF RESEARCHERS TO APPLIED SUITABLE CONTROL METHODS TO INJECT POWER TO THE GRID. IN THIS DOCUMENT, A NONLINEAR CONTROL STRATEGY FOR A POWER CONVERTER IS PRESENTED. THE BACK-TO-BACK TOPOLOGY ALLOWS DECOUPLING GRIDS BY USING A DC LINK BETWEEN THEM. THE ENERGY TRANSFERENCE AND THE POWER QUALITY HAVE TO BE CONTROLLED. THUS, PRIMARY CONTROLLERS HAVE TO DESIGN TO MEET CERTAIN VALUES. LOADS SENSITIVE TO VOLTAGE VARIATIONS NEED TO BE HANDLED CORRECTLY. THE PROPOSAL IS TESTED BY SIMULATION, AND THE RESULTS VALIDATE THE PROPOSAL.
