ANALYSIS AND SIMULATION OF A THREE-PHASE DELTA INVERTER FOR A STAR-CONNECTED RL LOAD

Abstract

In this study, analysis and simulation of the electrical and mathematical model of a 3-phase and 3-switch delta inverter that fed a three-phase RL load were performed. First, the Matlab/Simulink model of the inverter was created. In this model, an RL load of R=10Ω and L=0.005 H was fed and various simulations were made. The simulation results were obtained using 3 step switching technique for different conduction modes. The delta inverter that has a simpler structure and less switching elements than conventional inverter structures can be easily realized with low-cost microcontrollers.
