Modified Z-Source Converter for PV Application
There has been an increase development in renewable energy application, so a Z-source (ZS)-based network combines through switched-capacitor (SC) converters provide a straightforward design semiconductor apparatus to have voltage stress at its minimum, gain at voltage and steady input current. A voltage doubler circuit is integrated with z-source converter which helps in voltage boosting at output. This circuit helps to improve or double the output voltage. For a small input voltage an improved output voltage can be obtained. The power switch duty cycle is reduced in any way by the suggested converters, in contrast to several other ZS-based topologies that are already present in the literature. Hence voltage gain is improved and voltage stress across switch is reduced. These qualities make the suggested converters suitable choices for PV applications that require the interface of solar photovoltaic panel (PV) through a dc bus. For a load of 100W which provides efficient modified converter.
