This paper presents an optimization possibility of the voltage-fed continuous input current quasi-impedance source inverter (qZSI) by the introduction of the two-stage quasi-Z-source network (qZS-network). The two-stage qZS-network could be derived by the adding of one diode, one inductor and two capacitors to the traditional qZSI. The proposed two-stage qZSI inherits all the advantages of the traditional...
This paper presents a new step-up DC/DC converter topology with high-frequency isolation intended for residential fuel cell power systems. In contrast to traditional voltage source converters, the proposed topology utilizes the impedance network represented by a combination of two inductors and two capacitors on the input side of the DC/DC converter. Due to the specific feature of boosting input voltage...
