Abstract

Recently switching inductor Z-source inverter topology has been proposed to increase the boost factor. But the problem of stress on switch and capacitor is still remaining; hence an improved switched capacitor has been proposed to decrease the capacitor voltage stress. To design the control for this topology the transfer function is used. This paper presents the small signal analysis of the new topology; where, the state space averaging method is employed to achieve the transfer functions.
