Abstract
The main contribution of the paper is the proposal of Fuzzy Logic Controller (FLC) for three phase transformerless neutral point clamped inverters to eliminate harmonics in photovoltaic systems without requiring any modification on the multilevel inverter or any additional hardware. Multilevel level inverter technology has been widely used in the high power Medium voltage energy control systems [1]. In this paper, the authors have proposed a Fuzzy Logic Controller for three phase neutral point clamped inverter with PV system. They have used the neutral point clamped inverter in this paper because NPC inverter results in the low frequency voltage harmonics in the NP, which is the point between the two DC-link capacitors [7]. In primary side, PV system eliminates the harmonics by using the FLC, and the voltage controller is to produce regulated output voltage with low distortions under all loading conditions. A Fuzzy Logic Controller is developed by using MATLAB/SIMULINK for the chosen inverter having applications in the PV system. FLC is found to have better performance. This paper presents a methodology to generate gating signal to control NPCVSI using MATLAB/SIMULINK.
