Simulation. Testing and Implementation of a Phase Locked Loop Used to Control a PV Micro Inverter
Phase, amplitude and frequency of the utility grid are critical parameters for the operation of the grid connected power conditioning equipments. In such applications, an accurate and fast detection of the phase angle of the utility voltage is essential to insure a correct generation of the reference signals. This paper mainly focuses on the simulation, test and the implementation of a specific Phase Locked Loop "inverse Park transformation PLL" that is used to control a PV Micro Inverter. The improvement consists of better harmonics filtering. Experimental results validate the effectiveness of the proposed method.
