Abstract :
This paper contributes to the ac small signal modeling and analysis of Switched Inductor Quasi Z-source Inverter (SL QZSI) in continuous conduction mode. In this paper a capacitor voltage control for the switched inductor Qusi Z-source inverter (SL QZSI) is designed based on small signal analysis. The shoot-through duty cycle modulation strategy for control the capacitor voltage has been described in detail in order to improve the transient response and simplify the controller design. Computer simulation results are used to validate control strategy.
