Abstract :
This paper presents a complex design of a 3-phase VSI inverter with methods initially used for the single-phase inverters. The design rules of the output LC filter are implemented into a generalized discrete model of the inverter. The dual discrete feedback loop ensures a good transient response after the step load change and dumps the periodical disturbances improving the inverter operation with a nonlinear rectifier load.
