Language: english

Annotation:

Focus is on the single-phase quasi-Z-source inverter with coupled inductor. State space averaging method is used for small-signal analysis. Small signal behavior of the converter expressed analytically in form of set of transfer functions. It can be used for controller design in closed loop system and analysis of inductor coupling.

Key words:

single-phase inverter, qZS network, small signal model
