A novel galvanically isolated quasi-Z-source DC-DC converter with a single switch is presented. It is derived from the conventional single-switch nonisolated quasi-Z-source DC-DC converter. The new topology is within the transformer based class of the galvanically isolated impedance-source DC-DC converters, while existing topologies are solely within the coupled inductor based class. This simple solution...
This paper presents a novel quasi-Z-source halfbridge galvanically isolated DC-DC converter intended for the photovoltaic applications. The topology could be envisioned as an alternative to the boost half-bridge DC-DC converter but the benefit of its symmetric structure reduces the threat of transformer saturation due to the dc flux. The proposed converter features the continuous input current and...
Impedance-source switched mode converters are an emerging technology in electric energy conversion. They overcome limitations of conventional solutions by the utilization of specific impedance-source networks. Previous review papers cover impedance-source networks. Focus of this paper is on the topologies of the impedance-source galvanically isolated DC/DC converter. These converters are particularly...
