Modeling and analysis of a single phase inverter system with PWM switch model

This paper proposed a generalized modeling methodology based on the PWM Switch Model for steady-state analysis and dynamic performance investigation of the single phase inverter. The motivation, algorithm and modeling methodology are presented. The developed models are verified against the switching models of both a half bridge dual buck inverter and a half bridge inverter in time domain to demonstrate the effectiveness of the modeling methodology. Input impedance of the half bridge inverter is also obtained for stability investigation of the cascaded two-stage power system.
