Abstract

AbstractThis paper aims to discussing three-phase inverter design and Control using feedback and feedforward controllers. These inverters convert direct current to sinusoidal voltages and currents in three phases. The behavior of feedback, feedforward controller, is addressed in the presence of DC source input disturbances. These disturbances cause by the direct current source (PV, batteries, etc.). After conducting the study and simulation, it establishes that the feedback controller is ineffective at stabilizing the system when the input disturbances happen; hence, the feedforward controller is used to achieve this objective. This review aims to establish a stable and controllable approach for a three-phase voltage source inverter that supplies the most frequently used applications (RL load) and investigates the behavior of feedback and feedforward controllers. Finally, the paper developed an optimization method for improving the performance of a realistic inverter under any load condition.KeywordsThree phase inverterFeedback controllerFeedforward controllerSmart controller
