A novel quadratic boost A-source impedance network is proposed to realize converters that demand very high voltage gain. To satisfy the requirement, the network uses an autotransformer where the obtained gain is quadratically dependent on the duty ratio and is unmatched by any existing impedance source networks and normal dc-dc converters with coupled magnetics at the same duty ratio and turns ratio...
This paper presents the steady-state analysis of the voltage-fed quasi-Z-source inverter (qZSI) with cascaded (two-stage) quasi-Z-source network (qZS-network). Cascaded qZS-network is derived by the adding of one diode, one inductor and two capacitors to the traditional qZSI. Main focus of this paper is on mathematical models of the cascaded qZS-converter. Static models were elaborated and analyzed...
