Abstract:
The three high step-up Z-source (ZS)-based dc-dc converters with PI controller, that are suggested in this article combine switched-capacitor (SC) cells with the traditional ZS network. The suggested converters with PI controller provide a straight forward design with a constant input current, high voltage gain, and minimal voltage stress on the semiconductor components. Additionally, the suggested converters do not place any restrictions on the duty cycle of the power switch, in contrast to some other ZS-based topologies that are currently in use in the literature. These qualities make the suggested converters with PI controller, suitable choices for PV applications that require the interface of a low-voltage solar photovoltaic (PV) panel with a high-voltage dc bus. The Proposed converter with PI controller have high voltage gain, simplicity of operation, lower voltage, and lower current stresses on the components. . There are constant voltage variations for converters' outputs as a consequence of changes at the load and source end. in order to achieve a constant output voltage regardless of the source or load change, proportional integral controller is also employed in the proposed system. The Proposed converter with PI controller have high voltage gain, simplicity of operation, lower voltage, and lower current stresses on the components.
