Abstract

Three-phase grid-connected voltage source inverter (VSI) acts as a key part of distributed generation (DG). The behavior of DG technologies that use dc sources such as photovoltaic and fuel cells relies mostly on the performance of the inverters. The dqo transformation and space vector pulse width modulation (SVPWM) are introduced for the control of the three-phase VSI. PI controller, fuzzy logic controller (FLC) and PI-FLC double-mode controller are studied to optimize the design of current controller. A better control strategy for the current controller is verified based on the results of the simulation and experiment.
