| Abstract | ||||
| This paper presents the analysis of a single-phase voltage soufce inverter with a second order filter. The differential equations describing the system behavior in the different modes of operation are given. A general state space model of the voltage source inverter is first derived. A linearized small signal dynamic model is then developed &om the system general model using perturbation and small signal approximation. Root locus analysis presents the study of the system parameters, which affect the system stability. A feedback output voltage control loop is inserted into the system with proportional-integral (PI) controller. Liapunov stability method is performed to determine the condition of the modulation index for stability. The simulation results are given and proved to yield good agreement when compared with the experimental results. | ||||
